Willingness and hesitancy towards the governmental free human papillomavirus vaccination among parents of eligible adolescent girls in Shenzhen, Southern China. BMC Womens Health 2024; 24:253. [PMID: 38654200 PMCID: PMC11036762 DOI: 10.1186/s12905-024-03083-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2023] [Accepted: 04/08/2024] [Indexed: 04/25/2024] Open
Abstract
BACKGROUND Since 2020, China has actively promoted HPV vaccination for eligible adolescent girls through various pilot programmes. This study investigated parental willingness and hesitancy towards the government-sponsored, free human papillomavirus (HPV) vaccination for eligible adolescent girls in Shenzhen, Southern China. METHODS From June to August 2022, a cross-sectional survey was conducted with parents of girls entering Grade 7, employing an adapted Vaccine Hesitancy Scale to assess vaccine hesitancy and logistic regression to identify factors influencing willingness to accept the free domestic vaccines. RESULTS Although only 3.4% of the 2856 respondents had their daughters vaccinated against HPV prior to the survey, 91.7% were willing to utilise the governmental vaccination services. Parents with children in public schools (χ2 = 20.08, p < 0.001), those with more secure medical insurance (χ2 = 4.97, p = 0.026), and parents who had received an HPV vaccine themselves (χ2 = 28.829, p < 0.001) showed more reluctance towards the free vaccines. Vaccine hesitancy was presented in a mere 2.1% but was a significant predictor of vaccine refusal, even after adjusting for multiple factors (adjusted OR = 15.98, 95% CI: 9.06, 28.20). Notably, about four-fifths of parents of unvaccinated daughters harboured concerns about the safety and efficacy of the domestic vaccine. CONCLUSIONS Although parents show a strong inclination to utilise the government vaccination services, their vaccine hesitancy, driven by safety concerns and a preference for imported vaccines, remains a significant barrier for rolling out vaccination coverage. This study highlights the need for multifaceted intervention strategies that address these issues to enhance HPV vaccine uptake effectively.

Knowledge and beliefs of Greek parents towards HPV infection and vaccination - are they willing to vaccinate their sons? Int J Adolesc Med Health 2024; 36:61-68. [PMID: 38353174 DOI: 10.1515/ijamh-2023-0144] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Accepted: 01/17/2024] [Indexed: 03/02/2024]
Abstract
OBJECTIVES Human papillomavirus (HPV) stands as one of the prevalent sexually transmitted infections (STIs) and serves as the primary factor behind nearly all instances of cervical cancer, along with various other non-cancerous conditions like genital warts. Our objective was to explore the knowledge and beliefs of Greek parents regarding HPV infection and the vaccination of boys against HPV. METHODS A cross-sectional study took place at a university hospital located in the Peloponnese region of Greece, from January to June 2021. The study employed convenience sampling as its methodology, and data gathering involved the distribution of self-administered questionnaires to parents who had at least one son between the ages of 9 and 18 years. RESULTS The final sample consisted of 120 individuals. 65.8 % of parents have been informed about HPV vaccination, knew that the HPV vaccine provides immunity against genital warts (50 %), and that minimum of two doses is necessary (46.7 %). 30.8 % intended to vaccinate their boys against HPV if the vaccine were available for males. The most important reasons for vaccination were the perception that both genders share equal responsibility in the prevention of sexually transmitted infections (91.7 %) and the protection against cancer (87.6 %), whereas the fear of adverse reactions and the adequate knowledge about HPV-related diseases were most reported as reasons of the intentions to not vaccinate their sons with 31.7 % and 25.8 % respectively. CONCLUSIONS Although parents participating in the study know about HPV, however, there are significant lack of knowledge regarding HPV infection and the vaccine effects, which can significantly affect the acceptance of vaccination for boys.

Implementing the free HPV vaccination for adolescent girls aged below 14 in Shenzhen, Guangdong Province of China: experience, challenges, and lessons. Infect Dis Poverty 2023; 12:98. [PMID: 37899444 PMCID: PMC10614323 DOI: 10.1186/s40249-023-01149-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Accepted: 10/10/2023] [Indexed: 10/31/2023] Open
Abstract
Cervical cancer is a major public health concern in China, accounting for almost one-fifth of the global incidence and mortality. The recently prequalified domestic bivalent human papillomavirus (HPV) vaccine offers a practical and feasible preventive measure. In response to the global call for action, the National Health Commission issued an Action Plan to eliminate cervical cancer by 2030, with promotion of the HPV vaccination for school-aged girls as a critical step. Despite this, implementation of the vaccination has been patchy, with very low coverage among eligible girls. To address this, from December 2021 to December 2022, a demonstration project was launched in Shenzhen, Guangdong Province, to promote the inclusion of HPV vaccine in local immunisation programme and to address existing barriers to implementation. Using multiple sources of data, this article presents a case study of the demonstration project, analysing its impact on rolling out HPV vaccination among eligible girls and identifying any challenges encountered during implementation. The demonstration project has shown promising results in increasing the HPV vaccination rate, promoting public awareness and acceptance of the domestic HPV vaccine, and establishing a model for quickly scaling up the vaccination at the municipal level. The success of the project can be attributed to several factors, including strong governmental commitment, sufficient funding, multi-sectoral collaboration, ensured vaccine accessibility and affordability, improved vaccination services, and effective health education and communication strategies. Lessons learned from Shenzhen can provide valuable insights for future advocacy and implementation of the vaccination in other areas of China, but challenges must be addressed to achieve universal coverage. These include addressing vaccine hesitancy, expanding the programme to cover a broader age range, and ensuring consistent quality of vaccination services in primary care facilities. Overcoming these challenges will require innovative strategies, public-private partnerships, and sustained funding and resources. Future research should focus on evaluating the long-term effectiveness of the vaccination programme and identifying contextual factors that may impact its implementation in different settings. Overall, the effective control of cervical cancer in China will rely on the "political will" to ensure the incorporation of preventive interventions into policies and universal programme coverage.

Prospective Attitudes towards Respiratory Syncytial Virus (RSV) Vaccination: Validation of a Survey Instrument among Young Females in Jordan Pending Vaccine Authorization. Vaccines (Basel) 2023; 11:1386. [PMID: 37631954 PMCID: PMC10459998 DOI: 10.3390/vaccines11081386] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Revised: 08/11/2023] [Accepted: 08/18/2023] [Indexed: 08/28/2023] Open
Abstract
In May 2023, the U.S. FDA advisors endorsed Pfizer's pregnancy-administered vaccine (branded ABRYSVO) to protect infants from respiratory syncytial virus (RSV) infection. Vaccination can reduce the burden of RSV-related respiratory disease, with previous studies showing its substantial medical and financial burden in Jordan. However, pregnant women may exhibit hesitancy to get vaccinated due to concerns about potential risks to themselves or their fetuses. This study aimed to assess the acceptance of the RSV vaccine among young females and identify the determinants influencing their decision using a newly constructed instrument. A survey instrument was developed and validated, comprising 26 items to measure RSV vaccine acceptance. A cross-sectional study design was employed, with data collection from a sample of females aged 18 to 45 residing in Jordan during 5-6 July 2023, using a convenient approach via an online distributed questionnaire. The final study sample comprised 315 respondents, with 67.6% who have heard of RSV before the study. If the vaccine was safe, effective, and provided freely, 70.2% showed willingness to get the RSV vaccine, 15.2% resisted, and 14.6% were hesitant. Principal component analysis identified six internally consistent sub-scales with the following suggested themes: Advice, Burden, Conspiracy, Dangers, Efficiency, and Fear, comprising 21 items collectively as assigned as the "ABCDEF" scale for RSV vaccine acceptance. RSV vaccine acceptance in this study was associated with the advice and fear constructs. The validated survey instrument successfully captured important determinants of RSV vaccine acceptance among young females. RSV vaccine promotion efforts should focus on the following: enhancing vaccine education, improving trust in healthcare institutions and providers, reducing burdens through resolving cost issues and focusing on the role of social support, addressing safety concerns, and tailoring communication strategies to effectively promote the benefits of the vaccine. These insights can inform public health policies and interventions aiming to promote RSV vaccination and mitigate the burden of RSV-related diseases among infants. Follow-up studies are recommended with pregnant women as the target group to assess their attitude towards RSV vaccination and to confirm the validity of the conceived ABCDEF survey instrument.

Parental perceptions of the HPV vaccine for prevention of anogenital and oropharyngeal cancers. Vaccine X 2023; 14:100298. [PMID: 37113741 PMCID: PMC10126902 DOI: 10.1016/j.jvacx.2023.100298] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2023] [Revised: 03/30/2023] [Accepted: 03/31/2023] [Indexed: 04/29/2023] Open
Abstract
Background and Objectives Human papillomavirus (HPV) is implicated in the development of both anogenital and oropharyngeal cancers. Although HPV vaccination prevents the majority of anogenital and head and neck cancers (HNC), vaccination rates remain low, especially among males. Known barriers to vaccination are knowledge gaps and vaccine acceptability. The objective of this study is to explore parental knowledge, perceptions, and decision-making processes about HPV and HPV vaccination for both anogenital and HNC. Methods This qualitative study recruited parents of children and adolescents aged 8-18 to participate in semi-structured telephone interviews. Data were analyzed using thematic analyses, informed by an inductive approach. Results A total of 31 parents participated in the study. Six themes emerged: 1) knowledge about HPV vaccines, 2) perceptions and attitudes toward cancers, 3) role of child's sex in HPV vaccination, 4) decision-making processes around HPV vaccination, 5) communication with health care providers about HPV vaccines, and 6) influence of social networks. There were significant knowledge gaps about the vaccine's indications and effects, especially for males and HNC prevention. Parents had concerns related to risks of the HPV vaccine. They cited pediatricians as important sources of information about vaccination and critical to their decision-making. Conclusions This study identified many parental knowledge gaps related to HPV vaccination, with information about males, HNC prevention, and risks particularly lacking. As parents identified pediatricians as the most important sources of information regarding HPV vaccination, this should empower pediatricians to educate families about this important preventive health measure, with a focus on addressing concerns about vaccine risks.

Using the precaution adoption process model to understand decision-making about the COVID-19 booster vaccine in England. Vaccine 2023; 41:2466-2475. [PMID: 36933983 PMCID: PMC9935297 DOI: 10.1016/j.vaccine.2023.02.047] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2022] [Revised: 12/21/2022] [Accepted: 02/13/2023] [Indexed: 02/19/2023]
Abstract
BACKGROUND COVID-19 continues to pose a threat to public health. Booster vaccine programmes are critical to maintain population-level immunity. Stage theory models of health behaviour can help our understanding of vaccine decision-making in the context of perceived threats of COVID-19. PURPOSE To use the Precaution Adoption Process Model (PAPM) to understand decision-making about the COVID-19 booster vaccine (CBV) in England. METHODS An online, cross-sectional survey informed by the PAPM, the extended Theory of Planned Behaviour and Health Belief Model administered to people over the age of 50 residing in England, UK in October 2021. A multivariate, multinomial logistic regression model was used to examine associations with the different stages of CBV decision-making. RESULTS Of the total 2,004 participants: 135 (6.7%) were unengaged with the CBV programme; 262 (13.1%) were undecided as to whether to have a CBV; 31 (1.5%) had decided not to have a CBV; 1,415 (70.6%) had decided to have a CBV; and 161 (8.0%) had already had their CBV. Being unengaged was positively associated with beliefs in their immune system to protect against COVID-19, being employed, and low household income; and negatively associated with CBV knowledge, a positive COVID-19 vaccine experience, subjective norms, anticipated regret of not having a CBV, and higher academic qualifications. Being undecided was positively associated with beliefs in their immune system and having previously received the Oxford/AstraZeneca (as opposed to Pfizer/BioNTech) vaccine; and negatively associated with CBV knowledge, positive attitudes regarding CBV, a positive COVID-19 vaccine experience, anticipated regret of not having a CBV, white British ethnicity, and living in East Midlands (vs London). CONCLUSIONS Public health interventions promoting CBV may improve uptake through tailored messaging directed towards the specific decision stage relating to having a COVID-19 booster.

HPV Vaccination Adherence in Working-Age Men: A Systematic Review and Meta-Analysis. Vaccines (Basel) 2023; 11:vaccines11020443. [PMID: 36851321 PMCID: PMC9958554 DOI: 10.3390/vaccines11020443] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Revised: 02/09/2023] [Accepted: 02/13/2023] [Indexed: 02/17/2023] Open
Abstract
BACKGROUND Human papillomavirus (HPV) infection is the most common sexually transmitted viral infection in the world. HPV vaccination adherence rates in men are generally lower than in women. The aim of this systematic review and meta-analysis was to assess adherence to HPV vaccination in young working-age males (18-30 years old). METHODS A systematic review was performed using three databases: PubMed, Scopus, and Web of Science, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). RESULTS After duplicate removal, the initial search resulted in 478 eligible papers. With the exclusion of 425 papers after screening the abstracts, full texts of 53 articles were reviewed. Subsequently, 45 were excluded. Among the eight studies included, four (50%) examined the vaccination adherence in young adults through data registered in nationwide insurance or private companies' databases, three (37.5%) in young adults in different settings through data collected from surveys and questionnaires, and one (12.5%) an HPV vaccination campaign in a family medicine residency practice. CONCLUSION Adherence to HPV vaccination in men of working age (18-30 years) does not appear to be adequate (pooled prevalence 11%). In order to achieve a higher level of compliance, it is important to place an emphasis on vaccination campaigns in schools as well as in the workplace, after consultation with and approval from local, regional, and federal public health agencies.

Strengthening polio vaccine demand in Ghana: Understanding the factors influencing uptake of the vaccine and the effectiveness of different message frames. PLoS One 2023; 18:e0279809. [PMID: 36763581 PMCID: PMC9916648 DOI: 10.1371/journal.pone.0279809] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Accepted: 12/15/2022] [Indexed: 02/11/2023] Open
Abstract
BACKGROUND Ghana has experienced recent polio outbreaks. Behavioral insights can be used to understand behavior and create demand for the polio vaccine. METHODS This cross-sectional study is based on an interactive mobile phone survey that explored factors influencing the uptake of the polio vaccine among Ghanaian mothers with children younger than five years old. The survey also explores the mothers' intention to vaccinate their children in the future as well as an experiment with short polio vaccine voice message nudges to identify the most effective message frames in encouraging vaccination. The study sample was drawn from volunteers from a mobile service platform. Linear probability model regressions with Ordinary Least Squares (OLS) estimates were used to analyze the data. RESULTS In total, data from 708 caregivers was assessed. Out of the sample, 35% (n = 250) had not vaccinated their children against polio, around 8% (n = 53) of respondents stated they did not plan to do so, while 28% expressed intent to do so during the next polio vaccination campaign. Higher vaccination of children against polio, i.e. better uptake of the polio vaccine, appeared to be associated with children's caregivers knowing that polio causes paralysis (with a coefficient of 0.13 (95% CI: 0.02, 0.24), i.e. 13% more likely than not to have their child vaccinated). Higher vaccine uptake also appeared to be associated with the perception that the polio vaccine is safe (with a coefficient of 0.11 (95% CI: 0.01, 0.22), i.e. 11% more likely than not to have their child vaccinated). Another factor in increasing vaccine uptake is whether caregivers receive support from healthcare workers with a coefficient of 0.11 (95% CI: 0.02, 0.20), i.e. 11% more likely than not to have their child vaccinated. Crucially, difficulty accessing the polio vaccine appeared to be associate with a negative change in vaccine uptake (with a coefficient of -0.16 (95% CI: -0.23, -0.08), i.e. 16% less likely to have their child vaccinated). Satisfaction with the information provided by vaccinators was also associated with better vaccine uptake (with a coefficient of 0.12 (95% CI: 0.05, 0.20) i.e. 12% more likely than not to have their child vaccinated); and having seen or heard something negative about the polio vaccine with a coefficient of 0.10 (95% CI: 0.03, 0.17), i.e. 10% more likely than not to have their child vaccinated. The social norms message frame was statistically significant with a coefficient of 0.06 (95% CI: -0.004, 012). CONCLUSION The findings from this study suggest that most women with children under the age of 5 appear to have vaccinated their children against polio. Many more caregivers express an intention to vaccinate their children, never having done so before. The behavior and the intention to vaccinate are both driven by a number of factors that must be addressed to create demand for the polio vaccine. Targeted message frames appeared to be statistically significant drivers of vaccine uptake. However, more research is required to understand how they impact vaccine behavior and future intention for vaccination.

Malaysian Women's Viewpoint on HPV Screening and Vaccination: A Study on Barriers. Vaccines (Basel) 2023; 11:vaccines11010139. [PMID: 36679984 PMCID: PMC9863633 DOI: 10.3390/vaccines11010139] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Revised: 11/27/2022] [Accepted: 11/28/2022] [Indexed: 01/11/2023] Open
Abstract
Cervical cancer is the second most common cancer in low-income countries and the third most common cancer in Malaysia among women aged 15 to 44. This is a huge concern because of the high mortality rate compared to other countries. Cervical cancer is caused by a common sexually transmitted human papillomavirus (HPV). Of cervical cancer cases, 80% are attributed to serotypes 16 and 18; therefore, early detection of premalignant lesions and infections from these viruses is important. Diagnosis can be carried out by polymerase chain reaction (PCR)-based HPV DNA analysis and Pap smear, which act as a viable preventive strategy. (1) Background: This study determined the adoption of the human papillomavirus (HPV) vaccine and the willingness to get vaccinated in Malaysian women. (2) Methods: An online survey was conducted with women from across Malaysia to gather their views on the barriers that prevent them from accessing HPV services. Sentiment analysis was performed to detect and classify the comments into three groups (positive, neutral, and negative). (3) Results: A total of 449 opinions were received, and the findings revealed that 41.3% were not afraid to be diagnosed early, and were prepared to accept positive or negative screening results. In addition, 18.6% of those surveyed indicated that they feared a Pap smear and were very concerned that they would not get good results. Of the respondents, 36% believed in vaccination and preferred to know more about it; 43.24% claimed that their family members were very supportive towards screening and vaccination; and 21.3% felt embarrassed and were afraid to undergo the screening procedure, as they had no prior experience and were unsure of how the procedure was conducted. In addition, 40.5% indicated that they had no concerns about HPV testing and related procedures, as this information is widely available. Only a few respondents (8.1%) talked about the time constraints and busy work schedules that prevented them from going to medical appointments. The survey also revealed that women are prevented from participating in cervical cancer screening and vaccination programs due to a lack of knowledge, shyness, personal rumors, privacy issues, financial issues, a lack of access to medical services, and ignorance and beliefs about rumors spreading online. (4) Conclusion: Results indicate that awareness of HPV and related prevention measures among women is vague and that negative perceptions continue to exist. It is strongly advised to develop a well-designed and knowledge-based application on the efficacy of screening and vaccination among Malaysian women.

Abstract
PURPOSE Female secondary school students are the primary recommended population for human papillomavirus (HPV) vaccines. However, vaccine hesitancy may affect uptake. In this study, we assessed the vaccine hesitancy levels among the guardians of female secondary school students in China. METHODS We developed a questionnaire and conducted cross-sectional surveys among guardians of secondary school girls aged 12-19 years in mainland China based on the Increasing Vaccination Model and the Precaution Adoption Process Model. RESULTS We collected 3,225 valid samples. Among the participating guardians, 53.9% were vaccine hesitant, although only 0.9% had refused HPV vaccines. Some individual characteristics of guardians (e.g. sex, education/income level) were associated with understanding HPV vaccines. Better knowledge of HPV vaccines and communication with reliable sources of information were associated with vaccine nonhesitancy. Practical barriers such as vaccine shortage and busy schedules prevented nonhesitant guardians from vaccinating their children. DISCUSSION A substantial proportion of the guardians surveyed were HPV vaccine hesitant. Promoting HPV knowledge and communication with reliable sources (e.g. clinical doctors) could help fight against vaccine hesitancy.

Factors associated with HPV vaccine acceptability and hesitancy among Black mothers with young daughters in the United States. Front Public Health 2023; 11:1124206. [PMID: 37139381 PMCID: PMC10150885 DOI: 10.3389/fpubh.2023.1124206] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Accepted: 03/28/2023] [Indexed: 05/05/2023] Open
Abstract
Introduction Compared to other-race peers, Black women are disproportionately impacted by human papillomavirus [HPV] infection, related health outcomes, and cervical cancer mortality as a result of suboptimal HPV vaccine uptake during adolescence. Few studies in the United States have examined psychosocial determinants of HPV vaccine acceptability and hesitancy among Black parents. The current study integrated the health belief model and the theory of planned behavior to evaluate the extent to which psychosocial factors are associated with pediatric HPV vaccination intentions among this population. Methods Black mothers (N = 402; age range = 25 to 69 years, M = 37.45, SD = 7.88) of daughters ages 9 to 15 years completed an online survey assessing HPV infection and vaccine beliefs and attitudes across four domains: Mother's HPV Perceptions, Mother's Vaccine Attitudes, Cues to Action, and Perceived Barriers to HPV Vaccination. Participants indicated their willingness to vaccinate their daughter on a 5-level ordinal scale ("I will definitely not have my daughter get the vaccine" to "I will definitely have my daughter get the vaccine") which was dichotomously recoded for binomial logistic regressions. Results Half of the sample (48%) intended to vaccinate their daughter. Number of daughters, mother's HPV vaccine status, perceived HPV vaccine benefits, HPV vaccine safety concerns, pediatric HPV vaccine peer norms, and doctor recommendations emerged as independent factors of Black mothers' intentions to vaccinate their daughters against HPV when controlling for all other factors. Discussion In addition to medical training to increase doctor recommendation of the HPV vaccine for Black girls, population-tailored public health messaging aimed at promoting HPV vaccine acceptance among Black mothers is urgently needed. This messaging should engage community support and emphasize the benefits of vaccination for adolescent Black girls while also addressing parental concerns regarding the safety of pediatric HPV vaccination.

Abstract
BACKGROUND Vaccination serves as an efficient primary means of control for infectious diseases. However, in the case of the COVID-19 pandemic, pregnant women within the United States had the lowest rates of COVID-19 vaccination and reported the lowest intent to vaccinate. OBJECTIVES To explore the decision-making process for COVID-19 vaccination for people pregnant during the pandemic. DESIGN A secondary analysis of data from a mixed-methods study that examined the impact of COVID-19 on experiences of prenatal care, birth support, and delivery in the Southern United States. METHODS This study used a descriptive phenomenological approach to thematically analyze in-depth interviews (n = 20) with adult women who were pregnant by January 2020 and had their prenatal care and delivery during the pandemic beginning in March 2020. The transcripts were de-identified, coded, and thematically analyzed to saturation to identify drivers of COVID-19 vaccine decision-making based on COVID-19 vaccination status and timing. Comparative analyses were conducted to assess differences in decision-making processes based on race/ethnicity and parity. Participants also completed a sociodemographic survey that included their COVID-19 vaccination status. RESULTS Two themes emerged, the weighing of parallel risks and priorities from different sources resulting in vaccine decisional conflict and the need to reconcile that conflict via multiple strategies. All participants weighed priorities and risks from multiple areas of their lives and described internal conflict around vaccination. Participants described tailoring decisions to household dynamics, reconciling public and private values around vaccination, and the impact of their identities on the decision-making process. While many described concerns over vaccine safety and fetal health, uniquely, many highlighted weighing the impact of prior pregnancy loss history, with some choosing other preventive measures like social distancing or mask-wearing, which they deemed less risky. CONCLUSION Pregnant people make complex COVID-19 vaccination decisions, which must be considered in future vaccine messaging and advocacy for this group.

[PMID: 37744744 PMCID: PMC10515538 DOI: 10.1177/20552076231185430] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2022] [Accepted: 06/14/2023] [Indexed: 09/26/2023] Open
Abstract
Objective Alarmingly, the individuals' reach and coverage to get vaccinated in developing regions during the pandemic is a massive challenge for concerned authorities. This study aimed to demonstrate how cyberchondria play a significant role in a classical health belief model. Cyberchondria may influence cognitive factors (e.g. self-efficacy), which may contribute to an increase in attitude-behavior gap. Especially in the context of a health-centric scenario, it may discourage individuals to take protective measures. Method By using the cross-sectional research design, the authors conducted a quantitative survey in Pakistan and collected 563 responses from 303 male respondents (rural = 91; urban = 212) with (Urban M:35.5, standard deviation (SD):13.4) and rural M:37.5, SD:8.4). Result The findings indicate that decision self-efficacy among males is stronger than that in females. It dominates other determinants, which can dampen the individuals' intentions to get vaccinated. For instance, the effect of conspiracies and perceived seriousness was noted nonsignificant and weak. In females, perceived seriousness was stronger determinant than in males. In addition, the negative effect of decision self-efficacy was noted in the case of females, and conspiracy and cyberchondria had a negative role. Conclusion This study highlights valuable implications for future research in infodemic, health communication and health literacy, and practical implications for regulatory bodies and public administration.

A systematic literature review to clarify the concept of vaccine hesitancy. Nat Hum Behav 2022; 6:1634-1648. [PMID: 35995837 DOI: 10.1038/s41562-022-01431-6] [Citation(s) in RCA: 49] [Impact Index Per Article: 24.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2021] [Accepted: 07/13/2022] [Indexed: 11/25/2022]
Abstract
Vaccine hesitancy (VH) is considered a top-10 global health threat. The concept of VH has been described and applied inconsistently. This systematic review aims to clarify VH by analysing how it is operationalized. We searched PubMed, Embase and PsycINFO databases on 14 January 2022. We selected 422 studies containing operationalizations of VH for inclusion. One limitation is that studies of lower quality were not excluded. Our qualitative analysis reveals that VH is conceptualized as involving (1) cognitions or affect, (2) behaviour and (3) decision making. A wide variety of methods have been used to measure VH. Our findings indicate the varied and confusing use of the term VH, leading to an impracticable concept. We propose that VH should be defined as a state of indecisiveness regarding a vaccination decision.

Abstract
Vaccination has proven to be the most effective tool in controlling the COVID-19 pandemic. While pregnant individuals are considered to be a high-risk population and are more likely to experience adverse effects from COVID-19, vaccination rates among pregnant individuals are significantly lower than in the general population. The Health Belief Model (HBM), Theory of Planned Behavior (TPB), 3C model, 5C model, and 5A model have been used to assess vaccination hesitancy behaviors. In this paper, we review the use of each of these models to address vaccine hesitancy, with a focus on the pregnant population and the COVID-19 vaccine. The HBM, TPB, 3C model, and 5C model have demonstrated great versatility in their ability to evaluate, explain, and modify vaccine hesitancy and behavior. Up to date, the HBM and 3C models appear to be the most effective models to study and address vaccination hesitancy within the pregnant persons.

Development and validation of the cervical cancer knowledge scale and HPV testing knowledge scale in a sample of Canadian women. Prev Med Rep 2022; 30:102017. [PMID: 36281348 PMCID: PMC9587520 DOI: 10.1016/j.pmedr.2022.102017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Revised: 10/05/2022] [Accepted: 10/09/2022] [Indexed: 11/11/2022] Open
Abstract
Knowledge of cervical cancer and HPV testing are important factors in proactive and continued engagement with screening and are critical considerations as countries move towards the implementation of HPV-based primary screening programs. However, existing scales measuring knowledge of both cervical cancer and HPV testing are not up to date with the current literature, lack advanced psychometric testing, or have suboptimal psychometric properties. Updated, validated scales are needed to ensure accurate measurement of these factors. Therefore, the aim of this study was to develop and validate two scales measuring cervical cancer knowledge and HPV testing knowledge. A pool of items was generated by retaining relevant existing items identified in a 2019 literature search and developing new items according to themes identified in recent systematic reviews. Items were assessed for relevance by the research team and then refined through seven cognitive interviews with Canadian women. A web-based survey including the remaining items (fourteen for each scale development) was administered to a sample of Canadian women in October and November of 2021. After data cleaning, N = 1027 responses were retained. Exploratory and Confirmatory Factor Analysis were conducted, and Item Response Theory was used to select items. The final cervical cancer knowledge scale (CCKS) and HPV testing knowledge scale (HTKS) were unidimensional, and each consisted of eight items. CFA demonstrated adequate model fit for both scales. The developed scales will be important tools to identify knowledge gaps and inform communications about cervical cancer screening, particularly in the context of HPV-based screening implementation.

Pharmacy fall prevention services for the community-dwelling elderly: Patient engagement and expectations. HEALTH & SOCIAL CARE IN THE COMMUNITY 2022; 30:1450-1461. [PMID: 34137103 PMCID: PMC9290894 DOI: 10.1111/hsc.13475] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Revised: 05/19/2021] [Accepted: 05/26/2021] [Indexed: 06/12/2023]
Abstract
Medication use is an important risk factor for falls. Community pharmacists should therefore organise fall prevention care; however, little is known about patients' expectations of such services. This qualitative study aims to explore the expectations of community-dwelling older patients regarding fall prevention services provided by community pharmacies. Telephone intakes, followed by three focus groups, were conducted with 17 patients, who were aged ≥75 years, used at least one fall risk-increasing drug (FRID) and were registered at a community pharmacy in Amsterdam, the Netherlands. Some time of the focus groups was spent on playing a game involving knowledge questions and activities to stimulate discussion of topics related to falling. Data were collected between January 2020 and April 2020, and all focus groups were audiotaped and transcribed verbatim. The precaution adoption process model (PAPM) was applied during data analysis. Patients who had already experienced a fall more often mentioned that they took precautions to prevent falling. In general, patients were unaware that their medication use could increase their fall risk. Therefore, they did not expect pharmacists to play a role in fall prevention. However, many patients were interested in deprescribing. Patients also wanted to be informed about which medication could increase fall risk. In conclusion, although patients initially did not see a role for pharmacists in fall prevention, their perception changed when they were informed about the potential fall risk-increasing effects of some medications. Patients expected pharmacists to focus on drug-related interventions to reduce fall risk, such as deprescribing.

Abstract
Introduction The uptake of human papillomavirus (HPV) vaccination in France remains low. The aim of this study was to identify factors associated with the uptake of the HPV vaccine in girls aged 11–14 years in France. Methods We conducted a telephone survey among a quota sample of 1102 mothers of 11-14-year-old daughters residing in mainland France, using the French Survey Questionnaire for the Determinants of HPV Vaccine Hesitancy (FSQD-HPVH). The dependent variable was the uptake of at least one dose of the HPV vaccine in the daughter. The independent variables included the FSQD-HPVH item variables, the Global Vaccine Confidence Index item variables, the daughter’s age, and the mother’s socioeconomic status. Results Overall, 38.6% of the mothers indicated that their daughter received at least one dose of the HPV vaccine. The multivariate analysis revealed that agreeing with the statement that doctors/health care providers believe vaccinating girls against HPV was a good idea, and having asked questions to the attending doctor about HPV vaccines were associated with a higher HPV vaccine uptake (OR = 4.99 , 95% CI [2.09–11.89]; and OR = 3.44, 95% CI [2.40–4.92]). Mother’s belief that her daughter was too young to be vaccinated against HPV (OR = 0.16 , 95% CI [0. 09–0.29]) and lower daughter’s age (OR = 0.17 , 95% CI [0.10–0.28] for girls aged 11 compared to those aged 14) were found strongly inversely associated with HPV vaccination, followed by agreeing with the statement that the HPV vaccine was unsafe (OR = 0.42 , 95% CI [0.26–0.67]), identifying as true the statement that HPV was very rare (OR = 0.49 , 95% CI [0.31–0.77]), and the mother’s refusal of own vaccination (OR = 0.57 , 95% CI [0.40–0.80]). Conclusion We have identified important determinants associated with HPV vaccine uptake in France. Interventions designed to improve HPV vaccine uptake should be tailored to address these determinants.

A qualitative study of parental associations and beliefs regarding the HPV vaccination for Dutch boys. BMC Public Health 2022; 22:1188. [PMID: 35701791 PMCID: PMC9196852 DOI: 10.1186/s12889-022-13605-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2021] [Accepted: 06/08/2022] [Indexed: 11/24/2022] Open
Abstract
Background Human Papillomavirus (HPV) occurs in 80% of the sexually active population and may cause certain types of cancers among men and women. Vaccination against HPV could prevent cancers associated with HPV. The Dutch National Immunization Program (NIP) only includes HPV vaccination for girls, but the HPV vaccination for boys will be implemented in 2022. Little is known about the awareness of parents and their attitudes regarding the vaccination for boys. However, these concepts might influence the intention to vaccinate one’s child. Gaining insight in these factors could lead to more effective communication strategies. Methods This qualitative research aimed to explore parental associations and beliefs regarding the HPV vaccination for boys. In total, 16 interviews were conducted with parents. Topics discussed were primary associations with vaccinations, associations with HPV-vaccination and information needs regarding the HPV vaccination for boys. Results Most parents were unaware about HPV infections in boys as well as the possibility to vaccinate their sons. Furthermore, after hearing about the vaccine parents reported uncertainties about anticipated adverse effects of the vaccine. Other themes that emerged were difficulties with the proposed age at which boys would be offered the vaccination and low risk perception of the virus. Conclusion Public campaigns regarding (the HPV) vaccination should improve (parental) awareness about the virus and the vaccination, and increase knowledge. Moreover, it should address concerns regarding vaccination and be transparent about decision making. For example, a rationale why HPV vaccination is needed for boys who turn 10 years and its advantage to reducing risks for boys to contract HPV related cancers should be provided.

Abstract
Human papillomavirus (HPV) vaccination prevents cervical, head and neck, and anogenital cancers. However, global HPV vaccine coverage falls short of global targets and has seen unexpected and dramatic declines in some countries. This paper synthesizes the impact of HPV on the global burden of cancer and the potential benefit of HPV vaccination. Approximately 5% of the world’s cancers are specifically attributed to HPV. While the greatest global burden of HPV is cervical cancers in low- and middle-income countries, HPV-associated head and neck cancers are increasing in high-income countries and have surpassed cervical cancer as the primary HPV-associated cancer in some countries. Therefore, it is also critical to improve gender-neutral HPV vaccination. Understanding the modifiable drivers of vaccine acceptance and uptake is important for increasing HPV vaccination. The Behavioural and Social Drivers of Vaccination framework is broadly applied to identify key factors associated with HPV vaccination including domains concerning practical issues, motivation, social processes, and thinking and feeling. Among the behavioural strategies available to reduce the incidence and mortality of cancer, increasing HPV vaccination stands out as having unrealized potential to prevent disease, financial cost, and psychological distress. An understanding of the shifting burden of HPV and the factors associated with vaccination can be leveraged to regularly measure these factors, develop interventions to promote vaccine uptake, and improve global HPV vaccine coverage. Future research in diverse contexts is necessary to investigate the barriers and facilitators of global HPV vaccination.

Efficacy of a brief, altruism-eliciting video intervention in enhancing COVID-19 vaccination intentions amongst a population-based sample of younger adults: Randomized controlled trial (Preprint). JMIR Public Health Surveill 2022; 8:e37328. [PMID: 35544437 PMCID: PMC9153910 DOI: 10.2196/37328] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Revised: 04/28/2022] [Accepted: 05/07/2022] [Indexed: 11/22/2022] Open
Abstract
Background High COVID-19 vaccine uptake is crucial to containing the pandemic and reducing hospitalizations and deaths. Younger adults (aged 20-39 years) have demonstrated lower levels of vaccine uptake compared to older adults, while being more likely to transmit the virus due to a higher number of social contacts. Consequently, this age group has been identified by public health authorities as a key target for vaccine uptake. Previous research has demonstrated that altruistic messaging and motivation is associated with vaccine acceptance. Objective This study had 2 objectives: (1) to evaluate the within-group efficacy of an altruism-eliciting short, animated video intervention in increasing COVID-19 vaccination intentions amongst unvaccinated Canadian younger adults and (2) to examine the video’s efficacy compared to a text-based intervention focused exclusively on non-vaccine-related COVID-19 preventive health measures. Methods Using a web-based survey in a pre-post randomized control trial (RCT) design, we recruited Canadians aged 20-39 years who were not yet vaccinated against COVID-19 and randomized them in a 1:1 ratio to receive either the video intervention or an active text control. The video intervention was developed by our team in collaboration with a digital media company. The measurement of COVID-19 vaccination intentions before and after completing their assigned intervention was informed by the multistage Precaution Adoption Process Model (PAPM). The McNemar chi-square test was performed to evaluate within-group changes of vaccine intentions. Exact tests of symmetry using pairwise McNemar tests were applied to evaluate changes in multistaged intentions. Between-group vaccine intentions were assessed using the Pearson chi-square test postintervention. Results Analyses were performed on 1373 participants (n=686, 50%, in the video arm, n=687, 50%, in the text arm). Within-group results for the video intervention arm showed that there was a significant change in the intention to receive the vaccine (χ21=20.55, P<.001). The between-group difference in postintervention intentions (χ23=1.70, P=.64) was not significant. When administered the video intervention, we found that participants who had not thought about or were undecided about receiving a COVID-19 vaccine were more amenable to change than participants who had already decided not to vaccinate. Conclusions Although the video intervention was limited in its effect on those who had firmly decided not to vaccinate, our study demonstrates that prosocial and altruistic messages could increase COVID-19 vaccine uptake, especially when targeted to younger adults who are undecided or unengaged regarding vaccination. This might indicate that altruistic messaging provides a “push” for those who are tentative toward, or removed from, the decision to receive the vaccine. The results of our study could also be applied to more current COVID-19 vaccination recommendations (eg, booster shots) and for other vaccine-preventable diseases.

Abstract
Background Reaching and maintaining high global human papillomavirus (HPV) vaccine uptake has been challenging. The impact of publicly funded HPV immunization programs and the interplay of sociodemographic, psychosocial and policy factors in maximizing vaccination is poorly understood. This observational study examined the impact of introducing publicly funded school-based HPV vaccination programs for boys directly on uptake in boys and indirectly on uptake in girls, while concurrently examining other important sociodemographic and psychosocial factors. Methods Data were collected from a national, longitudinal sample of Canadian parents of children aged 9-16 years during August-September 2016 (T1) and June-July 2017 (T2). Participants completed an online questionnaire measuring sociodemographic characteristics, vaccine knowledge and attitudes, health care provider recommendation, and HPV vaccine uptake. Analyses were conducted separately for parents of boys and girls using logistic regression analyses at T1 and T2. Jurisdictions with HPV vaccine funding for boys at both time-points were compared to those with funding at neither time-points and those that introduced funding between time-points. Findings The sample included parents of boys (n = 716) and girls (n = 843). In multivariable analyses, jurisdictions with funding for boys at both time-points had higher odds of vaccination (adjusted odds ratio, T1 = 10.18, T2 = 11.42; 95% confidence interval, T1 = 3.08-33.58, T2 = 5.61-23.23) than jurisdictions without funding at both time-points; however, funded jurisdictions did not have higher odds of vaccination compared to jurisdictions that newly introduced funding for boys. Vaccination was associated with consistent determinants in boys and girls including child's age, health care provider recommendation, perceived vaccine harms, and perceived vaccine affordability. Interpretation This gender-sensitive analysis highlights the interplay of sociodemographic, psychosocial, and policy factors that can improve HPV vaccination. Publicly funded school-based programs are an impactful strategy to increase vaccine uptake. Funding This work was supported by the Canadian Cancer Society Research Institute (#704,036). GKS was supported by the Vanier Canada Graduate Scholarship and Queen Elizabeth II Diamond Jubilee Scholarship programs. The funders of this work had no role in the data collection, analysis, or interpretation, or any aspect pertinent to the study.

Centralized Reminder/Recall for Human Papillomavirus Vaccination: Findings From Two States-A Randomized Clinical Trial. J Adolesc Health 2021; 69:579-587. [PMID: 33846054 PMCID: PMC9639215 DOI: 10.1016/j.jadohealth.2021.02.023] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2020] [Revised: 02/23/2021] [Accepted: 02/26/2021] [Indexed: 10/21/2022]
Abstract
PURPOSE Centralized reminder/recall (C-R/R) using Immunization Information Systems has been effective in increasing childhood immunization rates. Previously, C-R/R using autodialer for human papillomavirus (HPV) vaccine did not raise rates. We assessed C-R/R for HPV vaccine using other modalities and focused on younger adolescents. METHODS We conducted a three-arm pragmatic RCT in randomly sampled primary care practices in Colorado (n = 88) and New York (n = 136), proportionate to where adolescents received care. We randomized, within practices, adolescents aged 11-14 years who had not completed the HPV vaccination series to receive C-R/R using different modalities (Colorado: autodialer, mail, or control; New York: autodialer, text, or control). Up to two reminders were sent in intervention arms for each dose needed between 2/2017 and 12/2018. RESULTS In Colorado, no significant differences were found for series initiation (31.3% control, 31.1% autodial, 31.8% mail), with slight improvement for series completion in the autodialer arm (29.7% control, 31.1% autodialer, p = .04) but not the mail arm (30.9%, p = .06). No significant differences were found in New York for series initiation (24.1% for all arms) or completion (17.1% control, 16.9% autodial, 17.9% text). Adjusted analyses showed higher completion rates for the autodialer arm in Colorado but not for other arms. In Colorado, C-R/R reduced time to series completion by around 2 months. Cost per adolescent was $1.81 for mail; under $.40 for all other modalities. CONCLUSIONS C-R/R has less benefit for raising HPV vaccination rates than other studies have noted for childhood immunizations, although it may quicken series completion at little cost.

Abstract
IMPORTANCE Missed opportunities for human papillomavirus (HPV) vaccination during pediatric health care visits are common. OBJECTIVES To evaluate the effect of online communication training for clinicians on missed opportunities for HPV vaccination rates overall and at well-child care (WCC) visits and visits for acute or chronic illness (hereafter referred to as acute or chronic visits) and on adolescent HPV vaccination rates. DESIGN, SETTING, AND PARTICIPANTS From December 26, 2018, to July 30, 2019, a longitudinal cluster randomized clinical trial allocated practices to communication training vs standard of care in staggered 6-month periods. A total of 48 primary care pediatric practices in 19 states were recruited from the American Academy of Pediatrics Pediatric Research in Office Settings network. Participants were clinicians in intervention practices. Outcomes were evaluated for all 11- to 17-year-old adolescents attending 24 intervention practices (188 clinicians) and 24 control practices (177 clinicians). Analyses were as randomized and performed on an intent-to-treat basis, accounting for clustering by practice. INTERVENTIONS Three sequential online educational modules were developed to help participating clinicians communicate with parents about the HPV vaccine. Weekly text messages were sent to participating clinicians to reinforce learning. Statisticians were blinded to group assignment. MAIN OUTCOMES AND MEASURES Main outcomes were missed opportunities for HPV vaccination overall and for HPV vaccine initiation and subsequent doses at WCC and acute or chronic visits (visit-level outcome). Secondary outcomes were HPV vaccination rates (person-level outcome). Outcomes were compared during the intervention vs baseline. RESULTS Altogether, 122 of 188 clinicians in intervention practices participated; of these, 120, 119, and 116 clinicians completed training modules 1, 2, and 3, respectively. During the intervention period, 29 206 adolescents (14 664 girls [50.2%]; mean [SD] age, 14.2 [2.0] years) made 15 888 WCC and 28 123 acute or chronic visits to intervention practices; 33 914 adolescents (17 069 girls [50.3%]; mean [SD] age, 14.2 [2.0] years) made 17 910 WCC and 35 281 acute or chronic visits to control practices. Intervention practices reduced missed opportunities overall by 2.4 percentage points (-2.4%; 95% CI, -3.5% to -1.2%) more than controls. Intervention practices reduced missed opportunities for vaccine initiation during WCC visits by 6.8 percentage points (-6.8%; 95% CI, -9.7% to -3.9%) more than controls. The intervention had no effect on missed opportunities for subsequent doses of the HPV vaccine or at acute or chronic visits. Adolescents in intervention practices had a 3.4-percentage point (95% CI, 0.6%-6.2%) greater improvement in HPV vaccine initiation compared with adolescents in control practices. CONCLUSIONS AND RELEVANCE This scalable, online communication training increased HPV vaccination, particularly HPV vaccine initiation at WCC visits. Results support dissemination of this intervention. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03599557.

Barriers towards HPV Vaccinations for Boys and Young Men: A Narrative Review. Viruses 2021; 13:v13081644. [PMID: 34452508 PMCID: PMC8402923 DOI: 10.3390/v13081644] [Citation(s) in RCA: 26] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2021] [Revised: 08/07/2021] [Accepted: 08/17/2021] [Indexed: 12/24/2022] Open
Abstract
Background: HPV vaccination of both girls and boys can protect against infection and eliminate the risk for HPV-associated cancer. Due to a common misconception that the virus only poses risks to women, vaccine coverage is suboptimal among men in many countries. It is urgent to identify barriers to vaccination of boys and men. Methods: We conducted a narrative review of publications examining attitudes and beliefs regarding HPV vaccination for boys and young men. The electronic databases searched were PubMed, PsychInfo and Scopus (December 2020; last update July 2021). A total of 103 original articles were included in the final analysis. Results: The central barriers against vaccination of boys and men are: (1) lack of knowledge, (2) vaccine hesitancy in general, (3) lack of recommendation from and/or discussions with healthcare providers, (4) cost and logistics, and (5) the idea that HPV vaccination may promote promiscuity. Men who have sex with men and families belonging to ethnic minorities express a need for information tailored to their situation. Conclusions: Boys should be included in national immunization programs and men should also be offered catch-up vaccinations. Future studies should focus on addressing vaccine hesitancy and developing interventions to promote pan-gender HPV vaccination.

School-based HPV vaccination positively impacts parents' attitudes toward adolescent vaccination. Vaccine 2021; 39:4190-4198. [PMID: 34127299 DOI: 10.1016/j.vaccine.2021.05.051] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2020] [Revised: 05/13/2021] [Accepted: 05/19/2021] [Indexed: 12/31/2022]
Abstract
INTRODUCTION This qualitative study aimed to explore parental attitudes, knowledge and decision-making about HPV vaccination for adolescents in the context of a gender-neutral school-based Australian National Immunisation Program (NIP). METHODS Semi-structured interviews with parents of adolescents eligible for HPV vaccination were undertaken as part of an evaluation of a cluster-randomised controlled trial of a complex intervention in 40 schools (2013-2015). In this qualitative study, we purposively recruited a nested sample of parents from 11 schools across two Australian jurisdictions. Interviews explored parent knowledge and understanding of the HPV vaccine program; HPV vaccination decision-making; their adolescent's knowledge about HPV vaccination; and their adolescent's understanding about HPV vaccination, sexual awareness and behaviour. Transcripts were analysed using inductive and deductive thematic analysis. RESULTS Parents' of 22 adolescents had positive attitudes towards the program; the school-based delivery platform was the key driver shaping acceptance of and decision-making about HPV vaccination. They had difficulty recalling, or did not read, HPV vaccination information sent home. Some adolescents were involved in discussions about vaccination, with parents' responsible for ultimate vaccine decision-making. All parents supported in-school education for adolescents about HPV and HPV vaccination. Parents' knowledge about HPV vaccination was limited to cervical cancer and was largely absent regarding vaccination in males. CONCLUSIONS Parents' positive attitudes towards the NIP and inclusion of the HPV vaccine is central to their vaccine decision-making and acceptance. More intensive communication strategies including school education opportunities are required to improve parents' knowledge of HPV-related disease and to promote vaccine decision-making with adolescents.

Abstract
Although vaccination uptake is high in most countries, pockets of suboptimal coverage remain, such as those observed among ultra-orthodox Jews in Israel and elsewhere, posing a threat to both individual and public immunity. Drawing on the Precaution Adoption Process Model (PAPM), this study proposes a Non-Vaccination Stage Model (NVSM) to analyze the decision-making process among Non-Vaccinating Parents (NVPs), focusing on the ultra-orthodox Jewish population of Israel. In-depth interviews were conducted with 10 Israeli ultra-orthodox Jewish NVPs (mothers). The interviews revealed five stages in the participants' decision-making process: Being good mothers who vaccinate their children; Emergence of doubts regarding the risks of vaccination; Personal vaccination policy-hesitancy concerning vaccination; Decision not to vaccinate; Confirmation signs of what participants perceive as a wise decision. NVSM can help understand parents who consider non-vaccination to be healthier behavior and explore the various stages of their decision-making process. Differentiating among the various stages of NVPs' decision-making processes enables application of different intervention approaches by policymakers and healthcare practitioners.

Family as a health promotion setting: A scoping review of conceptual models of the health-promoting family. PLoS One 2021; 16:e0249707. [PMID: 33844692 PMCID: PMC8041208 DOI: 10.1371/journal.pone.0249707] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2020] [Accepted: 03/23/2021] [Indexed: 12/02/2022] Open
Abstract
Background The family is a key setting for health promotion. Contemporary health promoting family models can establish scaffolds for shaping health behaviors and can be useful tools for education and health promotion. Objectives The objective of this scoping review is to provide details as to how conceptual and theoretical models of the health promoting potential of the family are being used in health promotion contexts. Design Guided by PRISMA ScR guidelines, we used a three-step search strategy to find relevant papers. This included key-word searching electronic databases (Medline, PSycINFO, Embase, and CINAHL), searching the reference lists of included studies, and intentionally searching for grey literature (in textbooks, dissertations, thesis manuscripts and reports.) Results After applying inclusion and exclusion criteria, the overall search generated 113 included manuscripts/chapters with 118 unique models. Through our analysis of these models, three main themes were apparent: 1) ecological factors are central components to most models or conceptual frameworks; 2) models were attentive to cultural and other diversities, allowing room for a wide range of differences across family types, and for different and ever-expanding social norms and roles; and 3) the role of the child as a passive recipient of their health journey rather than as an active agent in promoting their own family health was highlighted as an important gap in many of the identified models. Conclusions This review contributes a synthesis of contemporary literature in this area and supports the priority of ecological frameworks and diversity of family contexts. It encourages researchers, practitioners and family stakeholders to recognize the value of the child as an active agent in shaping the health promoting potential of their family context.

Human papillomavirus vaccination uptake: a longitudinal study showing ethnic differences in the influence of the intention-to-vaccinate among parent-daughter dyads. Hum Vaccin Immunother 2021; 17:990-999. [PMID: 32966170 PMCID: PMC8018452 DOI: 10.1080/21645515.2020.1808411] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Accepted: 08/06/2020] [Indexed: 10/23/2022] Open
Abstract
INTRODUCTION It is unclear what role daughters play in the decision-making process regarding HPV vaccination. Therefore, we explored the impact of HPV vaccination intention among parents and their 12-13 year-old daughters on HPV vaccination uptake. METHODS In February 2014 parents/guardians and their 12-13 year-old daughters were invited to complete a questionnaire about socio-psychological determinants of the decision-making process regarding HPV vaccination. Vaccination status of the daughter was retrieved from the national vaccination database after the last possible vaccination date in 2014. The association between HPV vaccination uptake and intention, and determinants of intention, was jointly assessed using a generalized structural equation model, stratified by origin of parents (Dutch versus non-Dutch). RESULTS In total, 273 Dutch parent-daughter dyads and 165 non-Dutch dyads were analyzed for this study. HPV vaccination uptake was 90% (246/273) and 84% (139/165) in the Dutch and non-Dutch group, respectively. In the Dutch group, high parental intention (β = 2.3, 95%CI 1.2-3.3) and high daughters' intention (β = 1.5, 95%CI 0.41-2.6) were significantly associated with HPV vaccination uptake. In the non-Dutch group, high daughters' intention (β = 1.2, 95%CI 0.16-2.2) was significantly associated with HPV vaccination, but high parental intention was not (β = 0.52, 95%CI -0.47-1.5). Attitude was the most prominent socio-psychological determinant associated with vaccination intention among all groups. CONCLUSION In the non-Dutch group, only daughters' intention was significantly associated with HPV vaccination uptake, whereas in the Dutch group both the parents' and the daughters' intention were significantly associated with uptake. The role of the child in the decision-making process might need to be taken into account when developing new interventions focused on increasing HPV vaccination uptake, especially among individuals of non-Dutch origin.

A validated modification of the vaccine hesitancy scale for childhood, influenza and HPV vaccines. Vaccine 2021; 39:1831-1839. [PMID: 33676784 DOI: 10.1016/j.vaccine.2021.02.039] [Citation(s) in RCA: 29] [Impact Index Per Article: 9.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2020] [Revised: 02/17/2021] [Accepted: 02/18/2021] [Indexed: 11/23/2022]
Abstract
INTRODUCTION Vaccine hesitancy contributes to outbreaks of preventable disease worldwide. The Vaccine Hesitancy Scale (VHS), developed by the international WHO SAGE Working Group, has been validated previously for measuring hesitancy towards childhood vaccines; some psychometric properties were suboptimal. METHODS We collected data using large, nationally-representative samples of parents in the U.S. We adapted the VHS items, and additional hesitancy items, to assess hesitancy towards influenza and HPV vaccines in addition to routine childhood vaccines. We then used exploratory and confirmatory factor analysis to identify latent constructs and create modified scales for childhood (VHS-child), influenza (VHS-flu) and HPV (VHS-HPV) vaccines with improved psychometric properties. Finally, we compared hesitancy scores on the VHS-child, VHS-flu, and VHS-HPV, to self-reported receipt of each vaccine category, and compared subscale scores to assess whether drivers of hesitancy differed by vaccine category. RESULTS 2052 parents of children <18 years old completed the VHS-child and VHS-flu while 2020 parents of adolescents completed the VHS-HPV. A two-factor structure of 'risks' and a 'lack of confidence' was found for each vaccine category. Slight modifications to the VHS improved psychometric properties. Hesitancy was strongly associated with vaccine receipt: e.g., 76% of parents not hesitant towards influenza vaccine had vaccinated their child the past season, versus 9% of hesitant parents (p < 0.0001). Subscale scores also differed significantly between vaccines: lack of confidence was greater towards influenza (Median (IQR): 2.0 (1.2, 3.3)) and HPV (2.0 (1.3, 3.0)) vaccines than childhood (1.2 (1.0, 1.8), p < 0.0001 for both) vaccines; perceived risks of HPV vaccines (2.7 (1.7, 3.7)) were greater than for childhood vaccines (2.0 (1.3, 3.0), p < 0.0001). CONCLUSIONS Our modified VHS scales perform well psychometrically and allow for consistent measurement of the extent and reasons for hesitancy between vaccine categories. We suggest that future work use these scales to examine hesitancy towards other vaccines and to monitor hesitancy over time.

Prevalence and characteristics of HPV vaccine hesitancy among parents of adolescents across the US. Vaccine 2020; 38:6027-6037. [PMID: 32758380 DOI: 10.1016/j.vaccine.2020.06.074] [Citation(s) in RCA: 95] [Impact Index Per Article: 23.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Revised: 06/23/2020] [Accepted: 06/26/2020] [Indexed: 12/15/2022]
Abstract
BACKGROUND While many clinicians encounter parents or adolescents who refuse HPV vaccine, little is known about the prevalence of hesitancy for HPV vaccine nationally or its association with vaccination. METHODS In April 2019, we surveyed families with adolescents 11-17 years using a national online panel (Knowledge Panel®) as the sampling frame. We assessed the prevalence of HPV vaccine hesitancy with the validated 9-item Vaccine Hesitancy Scale (VHS). We used multivariate analyses to assess demographic factors associated with HPV vaccine hesitancy. We also assessed practical barriers to receipt of HPV vaccine and the relationship between barriers and hesitancy. Finally, we evaluated the association between both HPV vaccine hesitancy and practical barriers on HPV vaccine receipt or refusal. RESULTS 2,177 parents out of 4,185 sampled (52%) completed the survey, 2,020 qualified (lived with adolescent). Using a VHS cut-off score > 3 out of 5 points, 23% of US parents were hesitant about HPV vaccine. Hesitancy was lower among those with Hispanic ethnicity. At least one out of five parents disagreed that the HPV vaccine is beneficial for their adolescent, that the vaccine is effective, protects against HPV-related cancers, or that they followed their adolescent's health-care provider's recommendation about the vaccine. Many were concerned about vaccine side effects and the novelty of the vaccine. Adolescents living with vaccine-hesitant parents were less than one-third as likely to have received the vaccine (RR = 0.29, 95% CI 0.24, 0.35) or completed the vaccine series (RR = 0.29, 95% CI 0.23, 0.36), and were 6-fold more likely to have refused the vaccine because of parental vaccine-related concerns (RR = 6.09, 95% CI = 5.26, 7.04). Most practical barriers were independently associated with vaccine receipt but not with vaccine refusal. CONCLUSIONS HPV vaccine hesitancy is common nationally and strongly related to both under-vaccination and vaccine refusal.

Abstract
BACKGROUND AND OBJECTIVES The World Health Organization has designated vaccine hesitancy as 1 of the 10 leading threats to global health, yet there is limited current national data on prevalence of hesitancy among US parents. Among a nationally representative sample of US parents, we aimed to (1) assess and compare prevalence of hesitancy and factors driving hesitancy for routine childhood and influenza vaccination and (2) examine associations between sociodemographic characteristics and hesitancy for routine childhood or influenza vaccination. METHODS In February 2019, we surveyed families with children using the largest online panel generating representative US samples. After weighting, we assessed hesitancy using a modified 5-point Vaccine Hesitancy Scale and labeled parents as hesitant if they scored >3. RESULTS A total of 2176 of 4445 parents sampled completed the survey (response rate 49%). Hesitancy prevalence was 6.1% for routine childhood and 25.8% for influenza vaccines; 12% strongly and 27% somewhat agreed they had concerns about serious side effects of both routine childhood and influenza vaccines. A total of 70% strongly agreed that routine childhood vaccines are effective versus 26% for influenza vaccine (P < .001). In multivariable models, an educational level lower than a bachelor's degree and household income <400% of the federal poverty level predicted hesitancy about both routine childhood and influenza vaccines. CONCLUSIONS Almost 1 in 15 US parents are hesitant about routine childhood vaccines, whereas >1 in 4 are hesitant about influenza vaccine. Furthermore, 1 in 8 parents are concerned about vaccine safety for both routine childhood and influenza vaccines, and only 1 in 4 believe influenza vaccine is effective. Vaccine hesitancy, particularly for influenza vaccine, is prevalent in the United States.

Decision-making about HPV vaccination in parents of boys and girls: A population-based survey in England and Wales. Vaccine 2020; 38:1040-1047. [PMID: 31787415 PMCID: PMC6996150 DOI: 10.1016/j.vaccine.2019.11.046] [Citation(s) in RCA: 24] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2019] [Revised: 10/09/2019] [Accepted: 11/18/2019] [Indexed: 02/08/2023]
Abstract
BACKGROUND School-based HPV vaccination in the UK will soon be extended to boys. Based on other countries' experience, uptake may initially be lower in boys than girls. We assessed HPV vaccine attitudes and decision-making in parents of boys and girls, to explore sex differences and inform public health messages. METHODS We carried out a cross-sectional population-based survey using home-based interviews in spring 2019. Participants were adults in England and Wales, with a child in school years 5-7 (aged 9-12 and eligible for HPV vaccination within 3 years). Measures included awareness of HPV and the vaccine, demographic factors, previous vaccine refusal and (after exposure to brief information) whether participants would allow their child to have the HPV vaccine (decided to vaccinate; decided not to vaccinate; undecided). We also assessed vaccine attitudes. Data were weighted to adjust for non-response. Multinomial logistic regression was used to explore predictors of deciding to (or not to) vaccinate compared with being undecided. RESULTS Among 1049 parents (weighted n = 1156), 55% were aware of HPV and the girls' vaccination programme, but only 23% had heard of plans to vaccinate boys. After information exposure, 62% said they would vaccinate their child, 10% would not, and 28% were undecided. Parents of girls were more willing to vaccinate than parents of boys (adjusted odds ratio: 1.80 (1.32-2.45)). Positive attitudes and HPV/vaccine awareness were significantly independently associated with deciding to vaccinate. Previous vaccine refusal for a child was the strongest predictor of not wanting the HPV vaccine. CONCLUSIONS Our findings suggest a need for public health campaigns to raise awareness of plans to extend HPV vaccination to boys. Reassuringly only 10% of all parents were unwilling to vaccinate and our data suggest further information, including about safety and efficacy, may be important in supporting undecided parents to make the decision to vaccinate.

Using the precaution adoption process model to clarify human papillomavirus vaccine hesitancy in canadian parents of girls and parents of boys. Hum Vaccin Immunother 2019; 15:1803-1814. [PMID: 30735442 DOI: 10.1080/21645515.2019.1575711] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/29/2023] Open
Abstract
Background: Achieving optimal human papillomavirus (HPV) vaccine uptake can be delayed by parents' HPV vaccine hesitancy, which is as a multi-stage intention process rather than a dichotomous (vaccinated/not vaccinated) outcome. Our objective was to longitudinally explore HPV related attitudes, beliefs and knowledge and to estimate the effect of psychosocial factors on HPV vaccine acceptability in HPV vaccine hesitant parents of boys and girls. Methods: We used an online survey to collect data from a nationally representative sample of Canadian parents of 9-16 years old boys and girls in September 2016 and July 2017. Informed by the Precaution Adoption Process Model, we categorized HPV vaccine hesitant parents into unengaged/undecided and decided not. Measures included sociodemographics, health behaviors and validated scales for HPV and HPV vaccine related attitudes, beliefs and knowledge. Predictors of HPV vaccine acceptability were assessed with binomial logistic regression. Results: Parents of boys and girls categorized as "flexible" hesitant (i.e., unengaged/undecided) changed over time their HPV related attitudes, behaviors, knowledge and intentions to vaccinate compared to "rigid" hesitant (i.e., decided not) who remained largely unchanged. In "flexible" hesitant, greater social influence to vaccinate (e.g., from family), increased HPV knowledge, higher family income, white ethnicity and lower perception of harms (e.g., vaccine safety), were associated with higher HPV vaccine acceptability. Conclusions: HPV vaccine hesitant parents are not a homogenous group. We have identified significant predictors of HPV vaccine acceptability in "flexible" hesitant parents. Further research is needed to estimate associations between psychosocial factors and vaccine acceptability in "rigid" hesitant parents.

Vaccination perspectives among adolescents and their desired role in the decision-making process. Hum Vaccin Immunother 2019; 15:1752-1759. [PMID: 30735440 PMCID: PMC6746506 DOI: 10.1080/21645515.2019.1571891] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2018] [Revised: 12/21/2018] [Accepted: 01/10/2019] [Indexed: 12/22/2022] Open
Abstract
Background: To assess the knowledge and attitudes of middle school students toward vaccination, we measured their understanding of vaccine safety and effectiveness, expectations for communication with heath care providers, and their desired role in the vaccination decision-making process. Methods: A cross-sectional, self-administered survey was conducted among seventh and eighth grade students in a middle school in Upstate New York. Bivariate analyses were conducted to identify differences in perspective by gender, grade, and attitudes toward vaccination. Results: Of 346 students attending class, 336 (97.1%) participated. The majority of respondents were White (71.3%) and 11 to 13 years of age (78.2%). Boys were significantly more likely than girls to perceive vaccines to be very safe (48.4% vs 30.2%, p < 0.01) and very effective (49.7% vs 29.0%, p < 0.01). Approximately one-third of adolescents reported having a say in the decision to be vaccinated and a quarter of students expressed a desire for specific information about vaccines. Conclusions: This study found that young adolescents in a nonurban area of Upstate New York were generally marginalized in the vaccine decision-making process yet third of them indicated an interest in how vaccines work and a desire to participate in healthcare decisions. Interventions to improve vaccine uptake among adolescents should capitalize on this desire to understand vaccine safety, effectiveness and mechanism of action.
