Parental intention, attitudes, beliefs, trust and deliberation towards childhood vaccination in the Netherlands in 2022: Indications of change compared to 2013

Developing a practical tool for measuring parental vaccine hesitancy: A people-centered validation approach in Dutch

Vaccine hesitancy (VH) about routine childhood vaccinations drives falling vaccine uptake rates. This is a major public health challenge and therefore important to monitor uniformly. The challenge is that different methods are used to measure VH and that, in non-English language, there may not be an unequivocal translation of VH terminology. We aimed to develop and validate a method to assess VH in a simple and self-reported manner, with a mixed-methods study using a people-centered approach with a diverse group of parents and illustrated in Dutch. In the quantitative part, parents were asked to rate experienced vaccine hesitancy on a 10-point Likert scale, using five differently worded Dutch translations for VH. We analyzed internal consistency with Cronbach's alpha and correlation with the short parental attitudes about childhood vaccination (PACV-5) scale. A total of 532 parents participated in the survey. We found that the five worded alternatives measured the same construct, indicated by a Cronbach's alpha of 0.95. The wording resembling 'doubt' showed highest correlation with the PACV-5 score (coefficient -0.525, p < .001). In the qualitative part of this study, we conducted cognitive interviews with 12 lower educated parents to evaluate the comprehensibility and interpretation of the question and VH translations. The findings reinforced and added to the quantitative findings that 'doubt' is the preferred wording. Based on the integrated results, we developed the Vaccine Hesitancy Assessment (VHA) tool. We encourage its use for monitoring purposes at the time of decision-making as this may provide a window of opportunity for decision-support interventions.

Knowledge and Attitudes Regarding Respiratory Syncytial Virus (RSV) Prevention: A Systematic Review

Background: New strategies for respiratory syncytial virus (RSV) prevention are available and are in development, but their acceptance is crucial to their effectiveness. Objectives: This systematic review aims to summarize current quantitative and qualitative evidence regarding knowledge and attitudes relating to RSV prevention. Methods: Six databases (PubMed, Scopus, APA PsycArticles; APA PsycInfo; CINAHL Complete; Psychology and Behavioral Sciences Collection) and two preprint repositories (medRxiv and Preprints) were searched up until 23 December 2024 (PROSPERO: CRD42024602351). Results: Sixty-one articles were included, focusing on vaccination for the elderly and adults at risk (n = 10) or pregnant people (n = 24, of which 8 also examined preferences for maternal vs. infant immunization) and infant immunization (n = 27, of which 16 focused on palivizumab, with 6 focusing on adherence to its monthly administration). Eighteen articles assessed attitudes in healthcare professionals. Overall, findings showed limited knowledge and awareness of RSV but generally positive attitudes towards prevention strategies and moderate to high intentions and uptake rates. Protection against the disease and perceived severity promoted acceptance, whereas concerns about side effects hindered it. Maternal vaccination was more acceptable than infant immunization. Conclusions: Attitudes towards RSV prevention options were generally favorable. Should more options become available, preferences may depend on which options are available, their characteristics, and how they are framed and presented. These insights highlight the importance of education on RSV grounded in decision-making literature, while recognizing the likely favorable reception of preventive measures across target age-populations.

Navigating parental attitudes on childhood vaccination in Jordan: a cross-sectional study

This study investigated parental attitudes toward childhood vaccination in Jordan, focusing on acceptance, concerns, and perceptions. A cross-sectional survey conducted from January to February 2024 included 939 parents. Findings indicated that 85.4% (n = 802) of respondents received the COVID-19 vaccine, while only 25% (n = 229) vaccinated their children. Concerns regarding vaccine safety and efficacy were prevalent, with 63.9% (n = 600) expressing worries about side effects and 46.9% (n = 440) trusting immunization programs. Post-pandemic, 34% (n = 319) reported a more negative attitude. Logistic regression showed parents not vaccinating their children against COVID-19 were significantly less likely to exhibit positive attitudes toward childhood vaccination (OR = 0.412, p < 0.001). Older participants were more inclined toward negativity post-pandemic (OR = 1.031, p = 0.007). In conclusion, parental attitudes shifted post-COVID-19, reflecting hesitancy and decreased trust. Addressing concerns and restoring confidence are crucial, especially for children's health. Education through healthcare providers and dispelling social media misinformation are essential. Implementing strategies to enhance post-pandemic vaccine acceptance is imperative for preventing outbreaks of vaccine-preventable diseases.

The Impact of COVID-19 on DTP3 Vaccination Coverage in Europe (2012-2023)

BACKGROUND

The COVID-19 pandemic disrupted routine child immunization efforts, threatening to reverse progress in controlling vaccine-preventable diseases.

MATERIALS AND METHODS

We analyzed the impact of COVID-19 on DTP3 vaccination in Europe by comparing trends before and after the pandemic using time series data from 2000 to 2023. Employing joinpoint regression, chi-square tests, and segmented regression analysis, we assessed DTP3 vaccination trends and coverage changes.

RESULTS

The findings revealed significant regional disparities across Europe. Statistical models indicated reductions in DTP3 coverage in countries such as Ireland, Sweden, and Switzerland, whereas Ukraine and San Marino showed improvements.

CONCLUSIONS

There are variations in the effect of COVID-19 on DTP3 coverage rates, indicating the need for targeted public health strategies to address vaccine hesitancy, logistical barriers, and systemic inequities.

Child COVID-19 vaccine uptake among participants of the 2015 Pelotas (Brazil) Birth Cohort Study

OBJECTIVE

To analyze COVID-19 vaccine uptake in children and to investigate factors associated with two outcomes variables: (a) not even beginning; (b) not completing the COVID-19 vaccine series.

METHODS

We used data of children aged 6-7 years from the 2015 Pelotas c Birth Cohort Study. COVID-19 vaccination status was collected from immunization cards and National Immunization Program Information System. Adjusted analyses were performed using a hierarchical model to identify factors associated with the two study outcomes.

RESULTS

Among 3867 children, 20.7 % (95 % CI, 19.5 %-22.0 %) did not even begin the 2-dose primary COVID-19 vaccine series, and 28.2 % (95 % CI, 26.6 %-29.8 %) did not complete the series with the second dose. Children not even beginning the COVID-19 vaccine series were more likely to have a White mother, not to have obesity, to have a history of COVID-19 infection, to have received non-recommended drugs for COVID-19, to be afraid of needles, and to have an incomplete diphtheria-tetanus-pertussis (DTP) and poliovirus immunization schedule. Not completing the 2-dose series was associated with lower maternal age and education, mother's self-identification as White or Brown, lower household income, lack of access to health services, not having completed the DTP and poliovirus immunization schedule and living with a person with a history of infection with COVID-19.

CONCLUSION

The results highlight a vaccine-hesitant parents' group who chose not beginning the COVID-19 vaccine series of their children and, another group of parents who failure to complete the child's series due to difficulty accessing health services.
