Routine childhood immunization is one of the most effective methods of preventing infectious diseases in children. In Argentina, there has been a decline in routine immunization coverage since 2015, with very little evidence to date on underlying drivers of this steady decline. We administered an online nationwide behavioral insights survey in Argentina between July 1-25, 2022, targeting parents with at least one child under the age of 12 years. Our survey included 1504 parents, 7% (n = 111) of whom did not or only partially vaccinated their children. We found that, compared to the youngest parents (aged 18-24), older parents were less likely to under-vaccinate their children (e.g., 30-34 year-old parents: adjusted Odds Ratio (aOR): 0.31, 95% Confidence Interval (CI) 0.16-0.57). Parents who undervaccinated their children were more likely to take vaccination advice from parent and wellness social media influencers (parent influencers: aOR 2.51, 95% CI 1.46-4.31), and were less likely to trust the social media accounts of official health organizations (aOR 0.82, 95% CI 0.70-0.96). Furthermore, these parents had heightened concerns about routine immunizations, including the number of vaccines given to children and potential for adverse side effects. When asked whether they knew enough to make a vaccine decision for their children, parents who undervaccinated their children were more likely to report that they did not know enough about vaccines or the vaccination schedule to make a decision. These results offer important insights into parental concerns surrounding routine childhood immunization and suggest potential drivers of - and solutions to - the decline in routine immunization seen in Argentina since 2015.
常规儿童免疫接种是预防儿童传染病最有效的方法之一。在阿根廷，自 2015 年以来，常规免疫接种覆盖率有所下降，但迄今为止，几乎没有关于导致这一下降的根本驱动因素的证据。我们于 2022 年 7 月 1 日至 25 日在阿根廷进行了一项全国性的在线行为洞察调查，调查对象是至少有一名 12 岁以下儿童的父母。我们的调查包括 1504 名父母，其中 7%（n=111）的父母没有或仅部分为孩子接种疫苗。我们发现，与最年轻的父母（18-24 岁）相比，年长的父母不太可能为孩子接种不足（例如，30-34 岁的父母：调整后的优势比（aOR）：0.31，95%置信区间（CI）0.16-0.57）。未为孩子接种疫苗的父母更有可能接受父母和健康社交媒体影响者的疫苗接种建议（父母影响者：aOR 2.51，95% CI 1.46-4.31），而不太信任官方卫生组织的社交媒体账户（aOR 0.82，95% CI 0.70-0.96）。此外，这些父母对常规免疫接种更加关注，包括为儿童接种的疫苗数量和潜在的不良反应。当被问及他们是否了解足够多的信息来为孩子做出疫苗接种决定时，未为孩子接种疫苗的父母更有可能表示，他们对疫苗或接种时间表了解不足，无法做出决定。这些结果提供了关于父母对常规儿童免疫接种的关注的重要见解，并提出了自 2015 年以来阿根廷常规免疫接种下降的潜在驱动因素和解决方案。
