COVID-19 Vaccine Hesitancy in Caregivers of Hospitalized Children From 2020 Through 2023

Data on US caregiver perceptions on coronavirus disease 2019 (COVID-19) and COVID-19 vaccination are limited. We identified trends in and associations with COVID-19 vaccine hesitancy in caregivers of hospitalized children.

Cross-sectional surveys on pediatric COVID-19 disease and vaccine attitudes, behaviors, and beliefs were administered across study years (December 8, 2020-April 5, 2021, November 30, 2021-March 15, 2022, and October 26, 2022-March 15, 2023). English and Spanish-speaking caregivers of hospitalized children ages 6 months to 11 years were included. General vaccine hesitancy was assessed using the Parent Attitudes about Childhood Vaccines survey.

Of 1268 caregivers from diverse backgrounds, one-third vaccinated or intended to vaccinate their child. Half endorsed fear of their child receiving the COVID-19 vaccine and were concerned the vaccine was new. Over time, more believed "the COVID-19 vaccine does not work" and fewer agreed "children who are otherwise healthy can die from COVID-19." Study season (2022-2023), older child age, higher income, child receipt of influenza vaccine, caregiver receipt of COVID-19 vaccine, and not being worried about vaccine novelty were positively associated with child vaccination. Intent to vaccinate was negatively associated with study season (2022-2023), Parent Attitudes about Childhood Vaccines score ≥50, lack of child influenza and caregiver COVID-19 vaccination, lack of fear of their child "getting COVID-19" and being "worried that the COVID-19 vaccine is new." The majority who intended to vaccinate were willing to immunize before discharge.

Vaccine novelty and perceived lack of need were associated with refusal. Caregiver COVID-19 and child influenza vaccine acceptance were positively associated with COVID-19 vaccine acceptance. The inpatient setting offers the opportunity to improve vaccine uptake.
