Factors associated with pediatric vaccine hesitancy of parents: a cross-sectional study in Turkey

Aim: This study aims to determine the prevalence and associated factors of vaccine hesitancy in females with children aged 12 months to 6 years who receive service from the antenatal class of a tertiary hospital in Turkey. Method: The study group includes 370 parents receiving service from a tertiary hospital. The data collection tools of the study were a descriptive data form and the Parent Attitudes about Childhood Vaccines survey.The data were analyzed using chi-square analysis and logistic regression analysis. Results: In our study, the prevalence of vaccine hesitancy was determined as 13.8% and vaccine refusal prevalence as 4.8%. In univariate analysis, vaccine hesitancy was found to be significantly higher in mothers with a university education, who got pregnant with treatment, who were not trained about pediatric vaccines in the antenatal follow-up, who followed anti-vaccine groups on social media, and who did not use vitamin D and iron supplements regularly or never used for their child. Vaccine hesitancy was significantly higher in parents who stated that their information sources of vaccines were not scientific, who were worried about vaccine ingredients (aluminum, mercury, pig gelatine) and who used alternative medicine practices (p < .05). In multivariate analysis, the risk of vaccine hesitancy increases 3.05 times in pregnancies with treatment, 3.74 times in those who did not use vitamin D or iron preparations, 3.01 times in those who followed anti-vaccine groups on social media,2.93 times in parents who were worried about the vaccine ingredients. Conclusion: Our findings suggest that the prevalence of vaccine hesitancy and risk factors should be monitored closely in the following years.

Automated summary

This study found that the prevalence of vaccine hesitancy among parents receiving services from a tertiary hospital in Turkey is relatively high, influenced by factors such as education level, getting pregnant with treatment, lack of education on pediatric vaccines, following anti-vaccine groups on social media, and irregular or lack of vitamin D and iron supplement use for children.
