Parents' Behaviors and Experiences Associated with Four Vaccination Behavior Groups for Childhood Vaccine Hesitancy

Vaccine Adherence: From Vaccine Hesitancy to Actual Vaccination and Reasons for Refusal of Childhood Vaccines in a Group of Postpartum Mothers

BACKGROUND/AIM

Vaccine refusal or delay remains a significant public health concern, leading to lower vaccination rates and increasing the risk of preventable diseases.

PATIENTS AND METHODS

The study included 404 mothers and 413 children, assessing vaccination coverage and conducting telephone interviews with mothers who declined vaccines to understand their reasons.

RESULTS

Children of mothers who supported vaccination were more likely to be fully immunized compared to those with hesitant mothers. Among the incompletely vaccinated or unvaccinated children, 73.08% had mothers from the hesitant group (GNV). However, 90.05% of hesitant mothers still vaccinated their children with all recommended vaccines, while 9.95% maintained their refusal. Only 3.22% of the total sample, all from the GNV group, refused vaccination entirely. The primary reasons for refusal included fear of side effects, lack of trust in vaccines or the healthcare system, negative vaccination experiences, and influence from media or social platforms.

CONCLUSION

While vaccination behaviors may improve as a child grows, a significant proportion of hesitant parents continue to exist across different population groups, contributing to suboptimal vaccination coverage rates. The consistent implementation of unified, nationwide strategies aimed at increasing trust in vaccines and the vaccination process is essential for achieving protective vaccination rates.

Parental knowledge, attitudes, and practices toward vaccinating their children against influenza: a cross-sectional study from China

Aims

Influenza infection is a health burden in children, and the influenza vaccine is an important prevention strategy for flu illness. Parents play a crucial role in children's influenza vaccination. The study aimed to assess parental knowledge, attitudes, and practices (KAP) related to influenza illness for their children and explore factors that may impact their decisions.

Methods

This cross-sectional study was conducted in a tertiary hospital in Guangzhou from November 2022 to April 2023. Answers to KAP questions regarding influenza illness and vaccination were summed, with a total KAP score of 20. Univariate and multivariate logistic regression models and linear regression models were conducted to explore the factors associated with influenza vaccination. The results were presented as odds ratios (ORs), β, and 95% confidence intervals (CIs).

Results

Overall, 530 parents were respondents, of whom 162 (30.56%) had vaccinated their children during the past year. The mean KAP score (standard deviation) was 13.40 (3.57). Compared to parents who reported non-vaccinated for their children in the past year, the parents who reported an influenza vaccination have higher knowledge scores, attitude scores, practice scores, and total scores. Child body mass index, parental education level (under college), parental work (part-time), and more than two family members over 60 years old were negatively correlated with knowledge score. Child health condition and knowledge score were positively correlated with attitude score. Parental age was negatively associated with attitude score.

Conclusion

Though high awareness about influenza illness and vaccination for parents, the coverage rate of influenza vaccination in children was lower in Guangzhou. Implementing public health policies is necessary to spread knowledge about influenza illness and vaccination and to promote the practice of receiving the influenza vaccine in children. Education campaigns would help change the attitudes of parents toward vaccinating their children against the flu.

Adverse events following immunisation: Prospective cohort study evaluating Australian children presenting to specialist immunisation clinics

OBJECTIVE

Prior experience of an adverse event following immunisation is a known barrier to vaccination. Limited Australian data evaluating adverse event recurrence among children exists to inform clinical decisions. We aimed to assess adverse event following immunisation recurrence among children with prior adverse events and to evaluate if family history increased adverse event risk.

METHODS

A prospective cohort study was conducted from March 3rd until August 18th, 2023. Children ≤ 16 years with prior adverse events following immunisation in themselves or family were recruited from specialist immunisation clinics at two quaternary paediatric hospitals. Adverse event outcomes were collected via surveys administered at presentation, three, and eight days post vaccination, and analysed by key characteristics and potential risk factors.

RESULTS

Forty three of forty nine (43/49, 87.8 %) children enrolled received further vaccines. Of those who completed the follow up surveys, 50.0 % (16/32) reported an adverse event. Recurrence of prior adverse events occurred for 23.3 % (10/43, 95 % CI: 11.8 % - 38.6 %) of the cohort. Two of twelve (2/12, 16.7 %) participants with prior serious adverse events who received further vaccines reported a serious adverse event recurrence. No post review serious adverse events were observed in children with prior non serious adverse events. Neurological conditions were a risk factor for prior (neurological condition 3/3 versus no neurological condition 2/40, p < 0.001) and post review (neurological condition 2/3 versus no neurological condition 0/28, p = 0.006) post vaccination seizures. Family history had no relationship to post review adverse events (family history 5/8 versus no family history 11/23, p = 0.685).

CONCLUSION

Revaccination is safe for the majority of children with a personal or family history of adverse event following immunisation.

Childhood Vaccine Attitude and Refusal among Turkish Parents

We aimed to understand and resolve anti-vaccine attitudes by examining the factors associated with vaccine attitudes and exploring potential strategies to improve childhood vaccination rates. Between 2014 and 2021, a total of 628 families refused vaccination in Adiyaman. A total of 300 families accepted visits and were visited. During the visits, the families were administered a questionnaire to determine the reasons for vaccine rejection and their opinions on the matter. While providing general information about the vaccine, parents were encouraged to reconsider their decision, and at the end, parents completed the questionnaire. The questionnaire included sociodemographic questions, reasons for vaccine refusal, and a vaccine attitude scale. Among the participants in the study, 9.3% were convinced about the vaccine. The mean vaccine attitude scale score was calculated as 23.6 ± 2.5 (min = 15-max = 29). Significantly higher rates of persuasion were observed among fathers (17.3%) compared to mothers (7.7%) (p = 0.038). Participants who had received some vaccinations had a higher rate of persuasion (11.6%) compared to those who had not received any vaccinations (2.6%) (p = 0.02). Childhood vaccine refusal is a complex issue that has been the subject of numerous studies. Studies on this subject will increase awareness of vaccines.

A cultural evolutionary model of the interaction between parental beliefs and behaviors, with applications to vaccine hesitancy

Health perceptions and health-related behaviors can change at the population level as cultures evolve. In the last decade, despite the proven efficacy of vaccines, the developed world has seen a resurgence of vaccine-preventable diseases (VPDs) such as measles, pertussis, and polio. Vaccine hesitancy, an individual attitude influenced by historical, political, and socio-cultural forces, is believed to be a primary factor responsible for decreasing vaccine coverage, thereby increasing the risk and occurrence of VPD outbreaks. Behavior change models have been increasingly employed to understand disease dynamics and intervention effectiveness. However, since health behaviors are culturally influenced, it is valuable to examine them within a cultural evolution context. Here, using a mathematical modeling framework, we explore the effects of cultural evolution on vaccine hesitancy and vaccination behavior. With this model, we shed light on facets of cultural evolution (vertical transmission, community influences, homophily, etc.) that promote the spread of vaccine hesitancy, ultimately affecting levels of vaccination coverage and VPD outbreak risk in a population. In addition, we present our model as a generalizable framework for exploring cultural evolution when humans' beliefs influence, but do not strictly dictate, their behaviors. This model offers a means of exploring how parents' potentially conflicting beliefs and cultural traits could affect their children's health and fitness. We show that vaccine confidence and vaccine-conferred benefits can both be driving forces of vaccine coverage. We also demonstrate that an assortative preference among vaccine-hesitant individuals can lead to increased vaccine hesitancy and lower vaccine coverage.

Parental reports of vaccine information statement usage in Utah

BACKGROUND

Since the implementation in 1986, there is little research focused on vaccine information statements (VISs) use for vaccine education and parental perception.

PURPOSE

To explore parental reports of dissemination and use of VISs.

METHODS

Data for this pilot, cross-sectional, descriptive study were collected through an online survey in both English and Spanish.

RESULTS

Responses from 130 parents in one school district were analyzed. Most participants (67.7%) reported getting vaccine information from a pediatric health care provider. A majority (71.5%) said that VISs were included in the vaccination process. Approximately one third of participants (37.7%) reported reading some or all the VIS before their child was vaccinated, and more than half (59.3%) read some or all the VIS after their child was vaccinated.

CONCLUSIONS

While promising that many parents reported receiving a VIS, more than one quarter of parents reported they did not. Inadequate time to read and understand VIS information before an immunization may lead to limited parental understanding. Although some participants reported struggling to understand VISs, more than half said that VISs were helpful and would read another in the future.

IMPLICATIONS

Without appropriate use of vaccine education material, providers miss the opportunity to educate parents on the risks and benefits of vaccinating their children. Providers must be aware of literacy levels and vaccine attitudes and create appropriate opportunities for parents to read and learn about vaccines. VISs are valuable educational tools for patients and parents. Improvements are needed to improve both VIS clarity and dissemination.

State of Vaccine Hesitancy in the United States

Although the term "vaccine hesitancy" has achieved great prominence, the extent to which US parents have reluctance, doubts, or indecision when it comes to vaccines recommended for children and how such hesitancy is manifest are unclear. A narrative review approach that placed emphasis on recent data and published work is used to surface evidence and insights into the current state of US parent vaccine hesitancy. The assessment finds evidence that ∼6% to 25% of parents may be vaccine hesitant, that hesitancy is higher for influenza and HPV vaccines, and there are indications that addressing parent hesitancy has become more challenging.

COVID-19 Vaccine Hesitancy among Economically Marginalized Hispanic Parents of Children under Five Years in the United States

Hispanic children in the US have high rates of COVID-19-related hospitalizations and deaths. Following FDA emergency approval, COVID-19 vaccination rates for young children under five years have been alarmingly low, especially in border states with significant Hispanic populations. This study identified social and cultural determinants of COVID-19 vaccine hesitancy among economically marginalized Hispanic parents of children under five. In 2022, following FDA approval, 309 Hispanic female guardians in US border states responded to an online survey assessing parental intent to vaccinate their child, demographic characteristics, COVID-19 health and vaccine beliefs, trust in traditional sources of health information, physician and community support, and acculturation to Anglo American norms. The majority (45.6%) did not intend to vaccinate their child or were unsure (22.0%). Kendall's tau-b indicated vaccine acceptance was negatively associated with COVID-19 specific and general vaccine distrust, belief the vaccine was unnecessary, time living in the U.S., and language acculturation (range tb = -0.13 to -0.44; p = 0.05-0.001) and positively related to trust in traditional resources, doctor's recommendation, child's age, household income and parent education (range tb = 0.11 to 0.37; p = 0.05-0.001). This research highlights the importance of COVID-19 vaccination public health strategies that draw on Hispanic cultural values, community partnerships and enhanced pediatrician communication regarding routine and COVID-19-specific vaccinations.

Attitudes and perceptions of mothers towards childhood vaccination in Greece: lessons to improve the childhood COVID-19 vaccination acceptance

BACKGROUND

Maternal attitudes and beliefs have been shown to influence childhood vaccination coverage, resulting in under-vaccination, non-vaccination, and vaccination delay. This study aimed to investigate the mothers' attitudes and perceptions about vaccination for their children in Greece.

METHODS

This was an online cross-sectional study, conducted from 4 April to 8 June 2020. A self-administered questionnaire was used to collect information about mothers' and their children's socio-demographic characteristics, previous vaccination behavior, and mothers' attitudes and perceptions about childhood vaccination. Participants included adult mothers with at least one minor child.

RESULTS

One thousand eight hundred eighty-five mothers participated, with the majority (91.7%) believing in the usefulness of vaccines and that vaccines protect children from serious and life-threatening diseases. A larger percentage of mothers with higher educational attainment agreed/absolutely agreed that all vaccinations provided by the National Vaccination Program must be offered to their children (91.6%) (p = 0.02) and that vaccines protect children from serious and life-threatening diseases (92.9%) (p = 0.01). Significant more married/in cohabitation and not single-parent mothers agreed that vaccines are safe (53.5% and 53.4%, respectively). There were also several significant associations between maternal attitudes toward childhood vaccination and previous maternal vaccination practices [(e.g., adherence to recommended vaccination dosages (all p-values < 0.01), vaccination delays (all p-values < 0.05), and vaccination during pregnancy (all p-values < 0.01)].

CONCLUSION

Maternal attitudes and perceptions toward childhood vaccination are significantly influenced by sociodemographic factors and maternal vaccination practices. Revealing those is essential for public health officials in developing future strategies to improve childhood vaccination coverage and acceptance of new vaccines such as the COVID-19 vaccine.
