Opinions, attitudes, and barriers to pediatric vaccination in Argentina

In Argentina, vaccines included in the national calendar are mandatory, free of charge, and access to vaccination services with social equity for all stages of life are guaranteed by law. However, vaccination coverages are still suboptimal and have shown a constant decrease in the last five years. This study aimed to perform a survey to describe the parent's confidence, risk perception, sources of information and access barriers to vaccines and vaccination in Argentina. A survey was designed for parents in charge of children under 12 years of age to answer. The questionnaire was constructed based on validated questions of the international peer-reviewed literature adapted to our country's characteristics. The survey was performed on 1,202 respondents, covering all regions of Argentina, between 19th May and 18th June 2020. To highlight, 76.6 % were female and the mean age was 40.72 (±9.36 years). 9 % participants reported to assist to the private vaccination center, while 64 % and 23 % referred to take their children to the public vaccination point (primary care center and hospital, respectively). Additionally, respondents agreed that vaccines are safe (92 %), effective (94 %), and important for children to receive them (98 %). 48 % could identify-one or more barriers to vaccination, access and affordability were the most reported ones (74 %) being the lack of vaccine the main reason. In conclusion, this study showed that the great majority of parents trust in vaccines and health care teams but access and affordability reasons emerged as the main barriers to vaccination in our country.
