Persistently low readiness to vaccinate young children against COVID among vaccine adherent mothers in Vermont, USA.

Young children (0-4 years) represent the next population in whom the SARS-CoV-2 (COVID) vaccine will be available. Addressing parental feelings about vaccination will be important to optimize uptake. In this study, online surveys were administered in 78 perinatal women in the Northeast United States (Vermont) between January and July 2021. Women reported vaccine by indicating their plans to have their child vaccinated. Response choices included vaccinate as soon as possible, vaccinate but not immediately, or no intention to vaccinate. Subsequently, women rated their to vaccinate children if offered the COVID vaccine tomorrow on an 11-point scale from 0 (definitely not get the vaccine) to 10 (definitely get the vaccine). Factors influencing ratings were measured categorically. General vaccine hesitancy was measured with the Parent Attitudes about Childhood Vaccinations scale. While many individual participants changed readiness to vaccinate children between baseline and follow-up; readiness in the study cohort remained unchanged. Approximately 50% of participants were likely to have their young children vaccinated. Concerns about vaccine safety was the largest driver of hesitancy. Importantly, even in a cohort highly adherent to childhood vaccines, hesitancy toward general childhood vaccines predicted decreased readiness for young children to receive the COVID vaccine. Our data provide evidence that maternal attitudes about the COVID vaccine are not fixed but overall readiness remains low, that prior adherence to childhood vaccine schedules will not predict vaccine behavior related to the COVID vaccine, and that public health messaging should emphasize messaging targeting vaccine safety in children.
