Knowledge, attitudes and beliefs about vaccination in primary healthcare workers involved in the administration of systematic childhood vaccines, Barcelona, 2016/17

Knowledge and trust of mothers regarding childhood vaccination in Rwanda

INTRODUCTION

Knowledge and trust are some of the contributing factors to vaccine acceptance(VA) and Vaccine hesitancy (VH) is one of the top threats to global health. A significant drop in childhood vaccination has been observed in recent years. One important reason that influences mothers' choice to either postpone or avoid children's vaccinations is knowledge and trust in childhood vaccines. This study aimed to assess mothers' knowledge and trust on vaccination of their children, and to examine the association between vaccination knowledge and selected socio-demographic factors.

METHODS

A cross-sectional survey was conducted from January 2022 to March 2022 to assess the knowledge and trust of mothers regarding childhood vaccination. Data was collected with self-administered questionnaires. Multivariable logistic regression analysis was employed to assess factors associated with childhood vaccine knowledge and trust.

RESULTS

Of the 2,126 Rwandan parents who participated in the study, the proportions with good knowledge of - and good trust in childhood vaccination were 95.5% and 91.4%, respectively. The popular sources of information about childhood vaccination were health care professionals (91.8%) and mass media (28.9%). Multinomial logistic regression analysis showed that good knowledge of - and trust in childhood vaccination were associated with the relationship with child(ren), education, occupation, and monthly income. The Multinomial logistic regression also revealed that the determinants of good knowledge of - and trust in childhood vaccination were; caregiver (p = 4.0 × 10-4, adjusted Odds Ratio (aOR); 1.7, 95%C.I; 1.3 - 2.3), no formal educational status (p = 3.3 × 10-2, aOR; 1.7, 95%C.I; 1.0 - 3.0), the unemployed occupational status (p = 2.4 × 10-2, aOR; 1.2, 95%C.I; 1.0 - 1.4), and persons on more than $401 per month (p = 2.0 × 10-4, aOR; 3.5, 95%C.I; 1.8 - 6.8).

CONCLUSION

The majority of parents in Rwanda had both good knowledge of-and good trust regarding childhood vaccination. Public health strategies to promote vaccination, education programmes as well as improved communication tools between health care professionals/traditional leaders/religious leaders and parents need to be considered to achieve favourable vaccination attitudes and practices for all parents in Rwanda.

Knowledge, attitudes and perceptions of nursing students regarding vaccines

BACKGROUND

 Final-year nursing students are actively involved in the delivery of public immunisation programmes as part of workplace-based learning, and require adequate knowledge, clinical skills, and attitudes regarding vaccines. This study investigated the knowledge, attitudes and perceptions regarding vaccines of final year nursing students at a South African University.

METHODS

 This cross-sectional study, through the use of an online survey questionnaire, assessed the knowledge, attitudes and perceptions regarding vaccines and the Expanded Programme of Immunization of final-year nursing students registered at a South African University during the 2021-2022 academic year.

RESULTS

 There were 68 participants enrolled in the study (85% response rate). Participants displayed good knowledge regarding vaccines (average score of 52.54/70 ± 5.01 standard deviation [s.d.]), and overall positive perceptions of their training on vaccines and its safety. Knowledge gaps were identified in the mechanisms through which vaccines confer immunity in the human body and the cold chain requirements for the storage of vaccines. Of concern was the prevalent misconception among 78% of participants that vaccines are not effective.

CONCLUSION

 The findings of this study indicate that final year nursing students at the University of KwaZulu-Natal, South Africa have good knowledge regarding vaccines. However, an improved understanding of the mechanism of vaccines will aid nursing students to confront and address misperceptions by clients thereby reducing improving vaccine uptake. Curriculum planners should also consider the inclusion of communication strategies to address vaccine hesitancy.Contribution: The study contributes to data on nurse education regarding vaccines in the African context, and identifies areas to improve vaccine uptake.

Vaccine Hesitancy among Healthcare Workers in Europe: A Systematic Review

This study analyzes vaccine hesitancy (VH) among healthcare workers (HCWs) in 15 European countries. We have undertaken a systematic review by synthesizing data from 46 articles (between 2015 and 2022) encompassing 55,612 subjects. Despite the heterogeneity of the methods in the various studies, we found that physicians had consistently higher vaccination rates than nurses across different countries and different vaccines. Physicians' average vaccination rate was 79% across a selection of vaccines, while that of nurses was 62%. Concerns regarding vaccine safety, information gaps, and the responsibility of healthcare authorities in managing VH are highlighted by qualitative insights. This research contributes to our comprehension of the ways in which VH among HCWs is impacted by healthcare roles, vaccine types, and regional disparities. The insights gleaned from this analysis can serve as a guide for targeted interventions aimed at increasing vaccine acceptance and coverage in Europe, ultimately strengthening public health.

Healthcare workers' (HCWs) attitudes and related factors towards COVID-19 vaccination: a rapid systematic review

Herd immunity through vaccination is a key measure to control COVID-19 pandemic. However, vaccine hesitancy remains a public health threat, which is still common among healthcare workers (HCWs). This systematic review aimed to synthesise evidence on HCWs' attitudes towards COVID-19 vaccination and analyse associated factors to provide information for vaccine policy development and practice. We searched PubMed, Embase, ScienceDirect, Web of Science and three Chinese databases for literature published on 12 February 2021. Two researchers screened the literature independently, and 13 studies were included in the systematic review. Vaccine acceptance varied widely and ranged from 27.7% to 77.3%. HCWs had positive attitudes towards future COVID-19 vaccines, while vaccine hesitancy was still common. Demographic variables such as men, older age and physicians were positive predictive factors. Women and nurses had more vaccine hesitancy. Previous influenza vaccination and self-perceived risk were facilitators. Concerns for safety, efficacy and effectiveness and distrust of the government were barriers. Influences of direct (COVID-19) patient care towards vaccination intention were less conclusive. Tailored communication strategies were needed to increase the uptake rate of COVID-19 vaccines among HCWs. More importantly, more data and information on the safety and efficacy of vaccines should be provided with transparency.

Pediatricians’ Perceptions, Practices, and Barriers Regarding COVID-19 Vaccine for Children: A Cross-Sectional Survey in Ontario, Canada

Background

SARS-CoV-2 vaccination of all age-eligible populations is an important part of the COVID-19 pandemic response. In Ontario, vaccination coverage in 5-to-11-year-old children has remained lower than in other age groups. We sought to understand pediatricians’ perception, practices, and barriers to SARS-CoV-2 vaccination in children, particularly children aged 5-to-11 years, to inform interventions and promote capacity of pediatricians as vaccinators and vaccination promoters.

Methods

This is a descriptive, cross-sectional study consisting of an online self-administered questionnaire distributed to 1,313 pediatricians in Ontario. Descriptive statistics, including Chi-square or Fisher’s exact tests, were performed.

Results

In total, 152 Pediatricians responded (11.6% response rate), from February 17, 2022 to March 17, 2022. 78% of respondents were general pediatricians and 22% were pediatric subspecialists. Median years of practice was 17 (8-31), with 68% female, 32% male. Most pediatricians thought it was unlikely that children aged 5-to-11 years would become seriously ill from acute COVID-19 caused by Delta (66%) or Omicron (80%). 92% were very likely to recommend the COVID-19 vaccine for children aged 5-to-11 years. COVID-19 vaccine was perceived as safe, with higher safety perception in children aged 5-to-11 compared to 12-to-17 years (p<0.0001). COVID-19 vaccines were thought to be effective in reducing hospitalization or severe illness, and reducing SARS-CoV-2 infection, with higher perceived effectiveness against Delta compared to Omicron (p<0.0001). 97% felt confident counselling caregivers of children aged 5-to-11 years on the COVID-19 vaccine. Few pediatricians did not feel confident in accessing resources for health professionals (6%) or for patients/caregivers (12%).

Conclusions

Most surveyed pediatricians were very likely to recommend COVID-19 vaccination for children aged 5-to-11-years, perceived COVID-19 vaccines as safe and effective, and felt confident in their COVID-19 vaccine counselling for children aged 5-to-11 years. However, there remains areas for further training and capacity development.

Education on Vaccination Competence: an Intensive Course for Skillful Health Science Students

Background

Vaccination is one of the most successful and cost-effective interventions for public health. Studies have shown that health professionals who have good knowledge and positive attitudes towards vaccination are more likely to provide effective vaccination protection to people, including themselves. Therefore, health science students must acquire evidence-based knowledge during their education to meet the challenges of healthcare.

Objective

The aim of this study was to investigate the knowledge, attitudes and feedback of health science students who participated in the Educating Vaccination Competence (EDUVAC) Intensive Course.

Methods

A five-day Intensive Course was implemented for health science students, which included a pre-assignment. The EDUVAC Intensive Course used different teaching methods (lectures, workshops, interactive games, discussions), group work, study visits, and cultural programs to encourage students' motivation. For the purpose of the study, students filled out an online questionnaire after giving informed consent.

Results

Sample consisted of 31 health science students from five European Higher Institutions. They had very good knowledge on most knowledge questions. In the post measurement it was significantly greater and equal to 81%, p<0.001. Almost all students (93.5%) totally agreed that "It is important for adults to receive all recommended vaccines according to national guidelines". The statement "I have had an active attitude and participation in the Intensive Course" received 80.6% total agreement. Over 90.3% rated the Intensive Course as "excellent" or "above average".

Conclusions

After completing the EDUVAC Intensive Course, students felt confident in their vaccination knowledge and skills, which benefited their professional development.

Second Dose Measles Vaccination Utilization and Associated Factors in Jabitehnan District, Northwest Ethiopia

Background

Herd immunity against measles is essential to interrupt measles transmission, and this can only be attained by reaching at least 95% coverage for each of the 2 doses of measles vaccine provided in infancy and early childhood age group. It is important to provide everyone with 2 doses of the measles vaccine in order to effectively safeguard the population. Despite this, little is known about the second dosage of the measles vaccine utilization status and the factors that affect it. Therefore, this study aimed to assess second dose of measles vaccination utilization and its associated factors among children aged 24-35 months in Jabitehnan district, 2020.

Methods

A community-based cross-sectional study design was conducted at Jabitehnan District, Northwest Ethiopia, from September 1st, 2020 to October 1st, 2020. Systematic random sampling technique was used to select 845 mothers/caregivers who had children aged 24-35 months. Both bi-variable and multivariable logistic regression was fitted to identify the determinant factors of second dose measles vaccination utilization. Finally, the statistical significant variables were declared by using 95% CI and P value less than .05 in the multivariable logistic regression analysis. The Hosmer and Lemeshow test was used to check the model's fit to the data, and the variance inflation factor was used to assess multi-collinearity.

Results

The overall second dose of measles vaccination utilization was 48.1%, (95% CI: 44.7-51.6). Mothers with primary school education (AOR = 1.91, 95% CI: 1.15-3.17), information about MCV2 (AOR = 6.53, 95% CI: 4.22-10.08), distance from vaccination site (AOR = 3.56, 95% CI: 2.46-5.14), knowledge about immunization (AOR = 1.935, 95% CI: 1.29-2.90), and favorable attitude about immunization (AOR = 5.19, 95% CI: 3.25-8.29) were significantly associated factors with second dose of measles vaccination utilization.

Conclusion

Second dose measles vaccination utilization in the district was lower than the national target. Maternal education, distances from vaccination site, information about MCV2, and knowledge about immunization were significantly associated variables with second dose measles vaccination utilization. Therefore, in order to increase the utilization of the second dose of the measles vaccine, improved health education and service expansion to difficult-to-reach areas are required.

Factors influencing healthcare professionals' confidence in vaccination in Europe: a literature review

Health-care professionals (HCPs) have a fundamental role in vaccination, their own beliefs and attitudes affecting both their uptake and recommendation of vaccines. This literature review (n = 89) summarises evidence on HCPs’ perceptions of the risks and benefits of vaccination, trust, and perceptions of mandatory vaccination in Europe. HCPs across studies believed that vaccination is important to protect themselves and their patients. However, beliefs that some diseases such as influenza are less risky were reported by some HCPs as a reason for not getting vaccinated. Concerns about both short- and long-term side effects were identified among HCPs in most studies, such as those affecting the immune or neurological system. Mistrust toward health authorities and pharmaceutical industry was reported in some studies. The question of mandatory vaccination revealed mixed opinions, with some favoring self-determination and others viewing vaccination as a duty. This review highlights key factors influencing HCPs’ confidence in vaccination in Europe.

Factors affecting childhood immunization: Thematic analysis of parents and healthcare workers' perceptions

Immunization against common childhood diseases is an important strategy as it is critical for reducing the global child morbidity and mortality. This review explores the perceptions of parents and HCWs toward childhood immunization. The PRISMA guideline was used to search and include the studies. Relevant electronic databases were systemically searched for the years ranging from 2000 to 2021 to identify studies reported in English. Themes were then identified using thematic analysis. A total of 44 studies met the review criteria and were summarized and categorized into 4 themes: barriers to immunization, parental knowledge, attitude and behavior (KAB), health system factors and HCWs' KAB. This review found that immunization decision-making is a complex process. Parental KAB leads to immunization decisions. HCWs were also noted to be the trusted sources of immunization information. Further research can be conducted on how to improve parents' perceptions of immunization and immunization practices.

Knowledge of Silesia adult inhabitants regarding preventive vaccinations effect on cardiovascular diseases

OBJECTIVES

Protective vaccinations are important in maintaining health and reducing suffering from infectious diseases. Also, vaccine-preventable infectious diseases are associated with the development and progression of cardiovascular diseases.

AIM

The study aimed to test adults' knowledge of the role of protective vaccinations in the prevention of cardiovascular diseases, and their opinions on the quantity of the information provided by doctors in this regard.

METHODS

A total of 700 adults participated in the study, most of whom were women (500; 71.43%). The study used an original questionnaire containing questions covering vaccinations and cardiovascular diseases, and the general characteristics of the participants. The inclusion criteria for the study were 18 years of age and written informed consent to participate in the study.

RESULTS

Over 60% of the participants did not know of, or denied the possibility of, developing cardiovascular diseases as a result of avoiding required preventive vaccinations. More than half of the participants stated that there is no need to recommend influenza vaccination to patients with cardiovascular diseases. Over 70% of participants stated that family doctors did not provide sufficient information about protective vaccinations.

CONCLUSION

In these adults, knowledge of the role of preventive vaccinations in the prevention of cardiovascular diseases was low, and the quantity of the information provided by doctors about preventive vaccinations were considered to be insufficient. Public awareness of the effects of avoiding preventive vaccinations should be raised especially among people with CVD.

Resistencia de la población hacia la vacunación en época de epidemias: a propósito de la COVID-19

Objetivo.

El presente artículo busca exponer los hallazgos de una revisión de la literatura sobre la resistencia de la población frente a las vacunas y las principales razones que han influido en sus decisiones hacia a la inmunoprevención, con foco en la pandemia de la COVID-19.

Métodos.

Se realizó una búsqueda en la literatura utilizando los términos DeCs/MeSH, Anti-Vaccination Movement, Vaccination refusal, Epidemics, COVID-19, Impacts on health, relacionados entre ellos por los operadores booleanos OR y AND en Google Scholar, Medline, Lilacs e Ibecs; también se tuvieron en cuenta documentos de fuentes oficiales.

Resultados.

A lo largo de la historia, desde el inicio de la vacunación, la percepción de las personas hacia este procedimiento ha sido controversial, hay quienes aceptan lo que las autoridades sanitarias recomiendan y quienes alegan intenciones ocultas detrás de la inmunización; la vacuna contra el SARS-CoV-2 causante de la COVID-19 no ha sido la excepción.

Conclusiones.

La vacunación ha sido uno de los mayores logros científicos en términos de salud pública, un avance que, a pesar de sus beneficios, ha causado miedo, incertidumbre y suspicacias en la población. Por esta razón, resulta importante incrementar las acciones de educación para la salud en la población, con información clara, concisa y comprensible, y sustentada en fuentes confiables y verídicas, con el fin de disminuir la resistencia a la vacunación y evitar las enfermedades prevenibles.

Behavioural and Cognitive Attitudes of Paediatricians towards Influenza Self-Vaccination-Partial Mediation Model

(1) Background: This study aims to analyse the attitudinal components influencing paediatricians’ self-vaccination. (2) Methods: The national-cross survey was conducted among paediatricians involved in childhood vaccination within the immunisation program. (3) Results: A hypothetical model indicating the influence of cognitive and behavioural factors on influenza vaccination among paediatricians was verified based on a survey of Polish paediatricians. A simple mediation model, based on Triandis’ Theory of Interpersonal Behaviour, reflects a relationship in which knowledge and beliefs about outcomes contribute to whether paediatricians vaccinate against influenza. (4) Conclusions: The presented research shows that the pro-vaccination behaviours of paediatricians are not only influenced by cognitive factors but also the behavioural components of attitudes, which are equally important. The conclusions point to the pivotal role of shaping both knowledge and understanding of the effectiveness of immunisation programmes in building the pro-vaccination attitudes of paediatricians. (5) Practical Implications: This is the first representative study of Polish paediatricians to demonstrate how their attitudes and behaviour are related to self-vaccination. Its conclusions allow policymakers to develop programmes to support effective measures against the spread of infectious diseases through the self-vaccination of medical professionals.

Continuing education programme on vaccines for primary healthcare professionals: mixed-method protocol

INTRODUCTION

Vaccination is a fundamental intervention in disease prevention; therefore, the advice and recommendations of health professionals have a major influence on the population's decision to be vaccinated or not. Professionals must have sufficient competencies to carry out their work and recommend vaccination with evidence-based knowledge. The aim is to design and validate a strategy to improve professional competencies in vaccination to positively influence adherence and increase vaccination rates in the population.

METHODS AND ANALYSIS

Training will be designed based on evidence and previous studies and piloted with healthcare providers. To test changes in knowledge, a pretest and post-test will be conducted. To test feasibility, a think-aloud method will be used with participants and triangulated with focus groups using SWOT (strengths, weaknesses, opportunities and threats) analysis. Transfer will be measured using the questionnaire 'factors for the indirect evaluation of transfer' and an efficacy questionnaire 1½ months later; for satisfaction, an ad hoc questionnaire will be used. A summative approach will be used for the analysis of the focus groups and descriptive and bivariate statistics for the questionnaires.

ETHICS AND DISSEMINATION

This study was approved by the Andalusian Research Ethics Committee, Spain (approval number: 0524-N-20). The results will be made available to the public at journal publications and scientific conferences.

Confidence in a Vaccine against COVID-19 among Registered Nurses in Barcelona, Spain across Two Time Periods

OBJECTIVE

To report the vaccine hesitancy (VH) for a vaccine against COVID-19 in registered nurses in Barcelona, with measurements taken at two stages, prior to the vaccination campaign and once 75% vaccination coverage had been reached.

METHODS

A self-completed online survey was administered in December 2020 and again in July 2021 through the College of Nurses of Barcelona. It measured the prevalence of VH against a government-approved vaccine recommended by their employer, their intention to be vaccinated, perceptions of disease risk and vaccine protection, attitudes and beliefs to vaccination and social norm. Bivariate analysis according to VH and application time are presented.

RESULTS

2430 valid responses were obtained in the first measurement and 2027 in the second. At both times, 86% were women and 69% worked mainly in the public sector. Prior to the vaccine availability, VH was 34.2%, decreasing to 17.9%. Risk perceptions were significantly lower in those with VH compared to non-VH, in all groups studied and at both times, while safety and efficacy perceptions increased in all groups, significantly less in VH. The greatest benefit of the COVID-19 vaccine is perceived by pharmaceutical companies. VH nurses perceived a more hesitant social environment.

CONCLUSION

As the vaccination was rolled out, VH in nurses declined, with time improving the confidence in the safety and efficacy of the vaccines. Risk perceptions also decreased over time, except for the perception of severity in HCW where it increased. Trust in institutions impacts trust in vaccines.

Comparison of Predictors of COVID-19 Vaccination Intention Between Healthcare Workers and Non-Healthcare Workers in China

Background

Vaccination is an effective strategy to mitigate the spread of COVID-19. This study aimed to compare predictors of vaccination intention between healthcare workers (HCWs) and non-healthcare workers (non-HCWs) in China.

Methods

A web-based cross-sectional survey was conducted among HCWs and non-HCWs. Several bivariate analysis techniques, eg, crosstab with Chi-square, independent t-test and single factor ANOVA, were performed to analyze the correlation. After that, a series of multivariate binary regressions were employed to determine predictors of vaccination intention.

Results

Intention was closely and significantly related with gender, perceived vaccination knowledge, perceived importance and effectiveness of vaccine to prevent COVID-19. HCWs and non-HCWs were heterogeneous, since vaccination intention, perceived knowledge, and attitudes (eg, importance, severity, risk) toward COVID-19 or vaccine had statistically significant difference between the two groups. With comparison of predictors of vaccination intention, for HCWs, demographic factors were the major predictors of COVID-19 vaccination intention. Female HCWs and HCWs with a Master’s or higher degree were more hesitant about vaccination (P = 0.01 and P < 0.001, respectively), while HCWs had greater vaccination intention as their age increased (P = 0.02). For non-HCWs, perceived vaccination knowledge was the major predictor of COVID-19 vaccination intention (P < 0.001). Additionally, perceived importance and effectiveness of vaccine were predictors for both HCWs and non-HCWs.

Conclusion

Vaccination intention of HCWs was greater than that of non-HCWs in China. Measures should be taken to improve the vaccination rate based on the predictors of vaccination intention identified in this study. For HCWs, especially those with a high level of education or who were females, the safety and effectiveness of vaccines in use may reinforce their vaccination intention. For non-HCWs, popularization of general medical knowledge, including of vaccine-preventable diseases, may increase their vaccination intention.

Knowledge, attitudes and behaviors of Inonu University faculty members regarding childhood vaccine refusal

INTRODUCTION

Although there is a lot of scientific evidence that the benefits of vaccines outweigh their risks, hesitancy about the safety of vaccines can occur in every segment of the community. In this study, we aimed to determine the knowledge, attitudes, and associated factors of vaccine hesitancy among Inonu University faculty members regarding childhood vaccinations.

METHOD

This is a cross-sectional study, and 258 faculty members were included in the study. The questionnaire used in the study explored the sociodemographic characteristics of the faculty members and their knowledge, attitudes and behaviors regarding childhood vaccination. A chi-square test and a fisher exact test were used for statistical analysis.

RESULTS

Of the faculty members, 31.8% were hesitant about childhood vaccines, 51.9% stated that there were studies reporting the side effects of vaccines, 48.1% did not agree with giving booster doses of vaccines, 35.7% stated that vaccines could cause autism due to the chemicals contained in the vaccines. The most important information sources of university faculty regarding childhood vaccines members are scientific publications and health professionals.

CONCLUSIONS

Faculty members level of hesitancy about vaccines was high and since health professionals and scientific articles are the most important information sources of faculty members, misinformation here may affect their knowledge, attitudes and behaviors about vaccination.

TIPICO XI: report of the first series and podcast on infectious diseases and vaccines (aTIPICO)

TIPiCO is an annual expert meeting and workshop on infectious diseases and vaccination. The edition of 2020 changed its name and format to aTIPiCO, the first series and podcasts on infectious diseases and vaccines. A total of 13 prestigious experts from different countries participated in this edition launched on the 26 November 2020. The state of the art of coronavirus disease-2019 (COVID-19) and the responsible pathogen, the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), and the options to tackle the pandemic situation were discussed in light of the knowledge in November 2020. Despite COVID-19, the status of other infectious diseases, including influenza infections, respiratory syncytial virus disease, human papillomavirus infection, measles, pertussis, tuberculosis, meningococcal disease, and pneumococcal disease, were also addressed. The essential lessons that can be learned from these diseases and their vaccines to use in the COVID-19 pandemic were also commented with the experts.

Development and validation of the knowledge and attitude regarding childhood vaccination (KACV) questionnaire among healthcare workers: the Malay version

Health care workers play an important role in supporting childhood vaccination as they are the most trusted source of vaccine-related information for parents. However, there is limited validated tools to measure their knowledge and attitude on childhood vaccination. This study aims to develop and validate knowledge and attitude regarding childhood vaccination (KACV) questionnaire among healthcare workers. The questionnaire was developed based on literature reviews and underwent a sequential validation process, including content, face validity and exploratory factor analysis. However, the attitude section is unidimensional and has undergone reliability analysis only. The preliminary knowledge questionnaire contains 33 items and the attitude questionnaire consists of 17 items. The preliminary KACV showed a high item Content Validity Index and Face Validity Index. The final questionnaire consists of 10 items for knowledge and 15 items for attitude. The Cronbach alpha for the knowledge and attitude section were 0.896 and 0.861, respectively. KACV is a valid and reliable tool to measure healthcare workers' knowledge and attitude on childhood vaccination.

Knowledge and behaviors of nurses working at Inonu University Turgut Ozal Medical Center on childhood vaccine refusal

Among 10 global problems of 2019 determined by the World Health Organization, vaccine refusal was one of the problems mentioned. In this context, health services and health personnel whose main objectives are to keep individuals healthy and to prevent diseases have major responsibilities. This study aims to analyze knowledge and behavior of nurses working at Inonu University Turgut Ozal Medical Center on childhood vaccine refusal.This study, conducted between June and July 2019, is a descriptive cross-sectional study. It was conducted in a hospital located in Malatya in eastern Turkey. At the time of the study, 850 nurses work in this hospital. Sample size was calculated to be 263 at a confidence interval of 95% and strength of 80%. Chi-square test and Fisher's exact test were used in statistical analyses.In the present study, 31.7% of the participating nurses stated that they had concerns about childhood vaccines. Two-thirds of nurses stated that their knowledge on vaccines was from their education. The level of hesitance in those agreeing to the fact that vaccines caused autism and infertility, those stating that they did not trust vaccine-producing companies, and those stating that catching the disease was a better immunization method than vaccination was significantly higher than those not agreeing to these and those who were indecisive (p < .05).One-third of nurses was proven to have hesitance on childhood vaccines, and this rate is rather high. Nurses, being both health personnel and the communication channel for guiding parents, should be provided necessary training and practices in order to ease their hesitance on vaccination.

Attitude towards Vaccination among Health Science Students before the COVID-19 Pandemic

Health science students are tomorrow's health professionals, the duties of whom could include vaccination. This work examines the general attitude towards vaccination in students attending the Faculty of Nursing, Physiotherapy and Chiropody at a university in Madrid, Spain, using the 'Attitudes and Behaviour With Regard To Vaccination Among Health Science Students Questionnaire'. The results were subjected to multivariate analysis to identify the influence of sex, the degree being pursued, and 'course year'. The number of students vaccinated against influenza in the campaign preceding the present study was also recorded, as were the factors that influenced decision-making in this regard. A total of 934 students completed the questionnaire. Their beliefs regarding vaccination were positive (mean score 3.23 points out of 4), as was their behaviour (3.35/4). Their general attitude (all variables taken together) was therefore also good (3.27/4). Only 26.8% of the students had been vaccinated against influenza. Beliefs scores among the students of nursing in their more senior course years were significantly better than those recorded for all other groups. These students also showed the best general attitude towards vaccination and formed the largest group vaccinated against influenza. The results obtained are encouraging since nursing students are the most likely of future healthcare professionals to be involved in vaccination programmes.

Vaccine hesitancy among paediatric nurses: Prevalence and associated factors

Objective

This study describes the prevalence of vaccine hesitancy associated with the Catalan systematic childhood vaccination calendar and some related psychosocial determinants among paediatric primary care nurses in Barcelona (Spain).

Methods

Cross-sectional descriptive study. In 2017 we invited the paediatric nurses (N = 165) working in Barcelona public primary health centres with paediatric departments (N = 41) to participate. They answered a questionnaire with sociodemographic and behavioural variables: severity and perceived probability of contracting the diseases of the vaccines in the vaccination schedule; safety and protection offered by each vaccine; and beliefs, social norms, and knowledge about vaccines. Outcome variable was vaccine hesitancy, dichotomized into not hesitant (nurses who would vaccinate their own offspring), and hesitant (including those who would not vaccinate them, those who had doubts and those who would delay the administration of one or more vaccines). We performed bivariate analysis and adjusted logistic regression models.

Results

83% of paediatric nurses (N = 137) agreed to participate. 67.9% had the intention to vaccinate their children of all the vaccines in the systematic schedule. 32.1% of nurses experienced vaccine hesitancy, especially about the HPV (21.9%) and varicella (17.5%) vaccines. The multivariate analysis suggests associations between hesitancy and low perception of the severity of whooping cough (aOR: 3.88; 95%CI:1.32–11.4), low perception of safety of the HPV vaccine (aOR:8.5;95%CI:1.24–57.8), the belief that vaccines are administered too early (aOR:6.09;95%CI:1.98–18.8), and not having children (aOR:4.05;95%CI:1.22–13.3).

Conclusions

Although most paediatric nurses had the intention to vaccinate their own children, almost one-third reported some kind of vaccine hesitancy, mainly related to doubts about HPV and varicella vaccines, as well as some misconceptions. These factors should be addressed to enhance nurses’ fundamental role in promoting vaccination to families.

Vaccine Hesitancy: COVID-19 and Influenza Vaccine Willingness among Parents in Wuxi, China-A Cross-Sectional Study

Objectives: We aimed to (1) assess parental hesitancy about category A (Expanded Program on Immunization (EPI)) and B (non-EPI) vaccines, (2) assess parental willingness for COVID-19 and influenza vaccinations, and (3) explore the association of vaccination hesitancy of parents and healthcare workers (HCWs). Methods: The study was performed in Wuxi, eastern China between 21 September 2020 and 17 October 2020. Parents of children aged <18 years and HCWs were recruited from the selected immunization clinics. Vaccine hesitancy was assessed using the Strategic Advisory Group of Experts (SAGE) vaccine hesitancy survey (VHS) by summing the total score for 10 items (maximum 50 points). Results: A total of 3009 parents and 86 HCWs were included in the analysis. The category A VHS scores were significantly higher than the category B VHS scores (p = 0.000). Overall, 59.3% and 52.4% of parents reported willingness to avail COVID-19 and influenza vaccination for their children, respectively; 51.2% of the HCWs wanted to be vaccinated against COVID-19. Parental category B VHS scores were associated with HCW category B VHS scores (r = 0.928, p = 0.008). Conclusions: In China, parents are more hesitant about category B vaccines than category A vaccines. More than 40% of parents showed hesitancy and a refusal to use COVID-19 and influenza vaccines.

Vaccination attitudes, beliefs and behaviours among primary health care workers in northern Croatia

Primary health care workers (HCWs) provide almost all vaccine services in Croatia, so they play an essential role in vaccine recommendations and uptake. The aim of this study was to determine the level of vaccine hesitancy among primary HCWs, to identify differences between nurses and physicians in attitudes, beliefs and behaviours towards vaccination, and to determine predictors of vaccine hesitancy among HCWs. We conducted a cross-sectional study from July to December in 2018 among physicians and nurses employed in the services of epidemiology, public health, school medicine, pediatrics and general practice/family medicine in Primorje-Gorski Kotar County, a primarily urban region with a population around 300 000 in the northern part of Croatia. The list of primary HCWs offices was obtained from the Croatian Health Insurance Fond website. We used a self-administered questionnaire on their attitudes, beliefs and behaviours relative to vaccination. Obtained response rate was 65.5% (324/495) of eligible primary HCWs; 64.1% (143/223) of physicians and 66.5% (181/272) of nurses. Seventeen percent of HCWs were identified as vaccine hesitant, and in univariate analysis, we observed an association between HCWs occupation and their own vaccination against flu (p = 0.001), measles (p = 0.016) and HPV (p = 0.025). Nurses and physicians differed (p < 0.001) in their general attitude, beliefs and behaviours towards vaccination, with a higher level of hesitancy among nurses. In multiple logistic regression, those more likely to be vaccine-hesitant were nurses (AOR = 5.73, 95%CI = 2.48-13.24), those who were uncertain or would never receive a vaccine against measles (AOR=11.13; 95%CI=5.37-23.10) and HPV (AOR=5.02; 95%CI=2.60-9.74), as well as those who had encountered a serious adverse event following immunization (AOR=7.55; 95%CI=3.13-19.18). As personal hesitancy may have a negative impact on vaccination education and recommendations, and therefore vaccine coverage, it is necessary to implement interventions to increase vaccination knowledge and confidence among primary health care workers, especially nurses.

Measles among healthcare workers in Italy: is it time to act?

Vaccination of healthcare workers (HCWs) against measles is strongly recommended in Europe. In this study, we examined the impact of measles on Italian HCWs by systematically and quantitatively analyzing measles cases involving HCWs over time and by identifying the epidemiological characteristics of the respective measles outbreaks. We retrieved data on measles cases from the Italian national integrated measles and rubella surveillance system from January 2013 to May 2019. Additionally, we performed a systematic review of the literature and an analysis of the measles and rubella aggregate outbreaks reporting forms from 2014 to 2018. Our review suggests that preventing measles infection among HCWs in disease outbreaks may be crucial for the elimination of measles in Italy. National policies aiming to increase HCW immunization rates are fundamental to the protection of HCWs and patients, will limit the economic impact of outbreaks on the institutions affected and will help achieve the elimination goal.

Perceptions of French healthcare students of vaccines and the impact of conducting an intervention in health promotion

BACKGROUND

The perceptions of healthcare students of vaccines have been poorly explored and appropriate training strategies to address possible confidence gaps concerning vaccination for these future professionals is still a subject of debate.

METHODS

A questionnaire to assess the perceptions of vaccination and the feeling of preparedness to address patient concerns was submitted to 874 multidisciplinary healthcare students enrolled in the French program "Service Sanitaire des Etudiants en Santé" (SSES). The evolution of their perceptions during the year and the impact of having performed a primary prevention intervention in the context of the SSES program were assessed.

RESULTS

In total, 530 students of nursing (42.5%), medicine (31.5%), physiotherapy (11.3%), pharmacy (10.9%), and midwifery (3.8%) completed the questionnaires. Among them, 7.0% carried out an intervention within the topic "vaccination and hygiene" and 93.0% within another topic ("nutrition and physical activity" or "addiction"). A portion of the students showed traits of vaccine hesitancy, including specific concerns about side effects (61.5%) or the number of vaccines in the vaccination schedule (30.0%). They felt ill prepared to address vaccine-hesitant patients, with poor confidence of their knowledge about vaccines (52.5%), their ability to inform patients about the side effects (42.5%), the benefit/risk of adjuvants (51.7%), and the rules for introducing a new vaccine (51.9%). They showed significant differences in perception depending on their curriculum. Misconceptions and hesitancy concerning vaccines were significantly improved after the students had performed the primary prevention intervention, regardless of the topic.

CONCLUSIONS

A portion of French healthcare students show traits of vaccine hesitancy, with significant differences depending on the courses attended. Programs of health promotion, such as the French SSES program, which includes a primary prevention intervention conducted by multidisciplinary groups of students, may improve the global confidence of healthcare students concerning vaccination.

Investigating knowledge, attitudes, and practices regarding vaccinations of community pharmacists in Italy

The purposes of this cross-sectional study were to determine the level of knowledge, attitudes, and behaviors related to vaccinations among community pharmacists in Italy and to understand the characteristics associated with the different outcomes of interest. The data were collected between September 2018 and April 2019 using semi-structured telephone interviews among a nationally representative sample of community pharmacists. Out of 550 pharmacists who were contacted, a total of 389 responded yielding a response rate of 70.7%. Only 23.9% indicated correctly all ten mandatory vaccinations for newborn. Participants with a lower number of years since degree, employee compared to owners, those who often/always collected information about public’s immunization, and who have received information from educational activities were more likely to know all ten mandatory vaccinations for newborn. Almost all (91.7%) believed that they could play a prominent role in the educational interventions on vaccinations and 75.3% that they should be more engaged in these interventions. Only 23.7% had recommended HPV vaccine to 11–12 years-old adolescents. Pharmacists who have obtained information from educational activities, who knew all ten mandatory vaccinations for newborn, and who believed that they should be more engaged in vaccination interventions were more likely to recommend the vaccine. The HPV vaccine was less likely recommended by those who have obtained information from scientific journals, mass-media and internet, and educational activities compared to those who have not received any information, who worked a higher number of hours per week, who often/always collected data on immunization, and employee pharmacists compared to owners. The findings may be useful to design interventions that can overcome the knowledge gaps of community pharmacists and to improve vaccine recommendations.

The association between vaccination confidence, vaccination behavior, and willingness to recommend vaccines among Finnish healthcare workers

Information and assurance from healthcare workers (HCWs) is reported by laypeople as a key factor in their decision to get vaccinated. However, previous research has shown that, as in the general population, hesitancy towards vaccines exists among HCWs as well. Previous studies further suggest that HCWs with a higher confidence in vaccinations and vaccine providers are more willing to take the vaccines themselves and to recommend vaccines to patients. In the present study with 2962 Finnish HCWs (doctors, head nurses, nurses, and practical nurses), we explored the associations between HCWs' vaccination confidence (perceived benefit and safety of vaccines and trust in health professionals), their decisions to accept vaccines for themselves and their children, and their willingness to recommend vaccines to patients. The results showed that although the majority of HCWs had high confidence in vaccinations, a notable share reported low vaccination confidence. Moreover, in line with previous research, HCWs with higher confidence in the benefits and safety of vaccines were more likely to accept vaccines for their children and themselves, and to recommend vaccines to their patients. Trust in other health professionals was not directly related to vaccination or recommendation behavior. Confidence in the benefits and safety of vaccines was highest among doctors, and increased along with the educational level of the HCWs, suggesting a link between confidence and the degree of medical training. Ensuring high confidence in vaccines among HCWs may be important in maintaining high vaccine uptake in the general population.

Knowledge influences attitudes toward vaccination in Romania

Despite proven effectiveness and safety of vaccinations, immunization rates are decreasing across Europe, most countries having suboptimal vaccination coverage, leading to an increase in the number of cases of preventable contagious diseases. In recent years, the number of parents who have refused to vaccinate their children in Romania has decreased substantially, while the number of fatal complications due to measles outbreak is one of the highest in Europe. Since healthcare professionals have been identified as the main advocates for immunization, knowledge and attitudes of medical students and nurses is of particular interest. A cross-sectional survey was carried out on 278 participants, divided into three groups: 183 medical students, 54 nurses and 41 non-medical professionals. The questionnaire included questions on demographics of participants, personal experience with vaccines, knowledge and attitude toward vaccination. The data was collected, centralized and analyzed using statistical methods. The survey was given to the medical students at the beginning of the Immunology course and again at the end, to test whether information received influenced their responses. The study revealed that a great majority of participants were themselves vaccinated [N=262 (94%)] and had/or would vaccinate their children [N=247 (95%)]. Satisfactory overall knowledge about effectiveness and safety concerns was observed, with 98% (N=270) considering vaccines as useful and over 96% (N=276) correctly identified their usefulness. When asked about adverse effects, concerning numbers [N=32, (19%)] of medical students answered incorrectly. After the Immunology course, however, there was significant improvement in knowledge on this topic (P<0.001), correlating with a positive shift in attitude towards current and future vaccines. We predict that better knowledge about vaccines, their efficacy and safety would help build the health provider's confidence in recommending vaccination and thus increased coverage rates.

Knowledge of Human Papillomavirus (HPV), Attitudes and Practices Towards Anti-HPV Vaccination Among Israeli Pediatricians, Gynecologists, and Internal Medicine Doctors: Development and Validation of an Ad Hoc Questionnaire

Human papillomavirus (HPV) is a highly widespread virus which is responsible for one of the most common sexually transmitted infections. Two main preventative strategies exist: anti-HPV vaccination and cervical screening. Health-care workers play a key role in promoting public health campaigns; however, vaccine hesitancy is an often under-recognized challenge. To investigate the overall knowledge of HPV and HPV-related issues, as well as the attitudes and practices of health professionals towards recommending the anti-HPV vaccine, an ad hoc knowledge, attitudes, and practices (KAP) questionnaire was developed and validated in a sample of 139 Israeli pediatricians, gynecologists, and internal medicine doctors. The KAP questionnaire was found to be psychometrically valid and sound (with an r_KR-20 coefficient of 0.74 for the second part and a Cronbach's alpha of 0.85 for the third part). Furthermore, the present study confirmed the importance of health-care providers in recommending the immunization practice. Parents that had been strongly advised by health-care providers to vaccinate their children accepted immunization for their girls (odds ratio (OR) 1.09 (95% CI 1.04-1.14)) and boys (OR 1.06 (95% CI 1.02-1.10)), had a lower probability of deciding to postpone the immunization appointment (OR 0.81 (95% CI 0.66-0.98)), had fewer doubts and concerns about the vaccine (OR 0.69 (95% CI 0.54-0.89)), and had a lower probability of refusing the vaccination (OR 0.93 (95% CI 0.86-0.99)). Interestingly, the use of new, emerging tools such as ad hoc websites, applications, and other interactive devices reduced vaccine hesitancy (OR 0.90 (95% CI 0.82-0.99)) and concerns about the side-effects of the vaccine (OR 0.92 (95% CI 0.86-0.99)). However, among Israeli health-care workers, knowledge was generally moderate, with updated information lacking in about 30% of surveyed health-care providers and approximately 20% of them not recommending the anti-HPV vaccine among boys. This study has practical implications for policy- and decision-makers in that they should be aware of the overall level of knowledge among health-care workers and should implement ad hoc educational interventions to address gaps in knowledge and help medical providers routinely recommend the anti-HPV vaccine both to male and female children and adolescents.
