Understanding caregivers' decision to vaccinate childhood cancer survivors against COVID‐19

Background Vaccination against COVID‐19 is recommended for childhood cancer survivors (CCS). This study aimed to identify antecedents contributing to caregivers' decisions to vaccinate CCS aged 5–17 years against COVID‐19 by applying the Theory of Planned Behavior. Methods Participants in this cross‐sectional study completed an online survey assessing caregiver attitudes, subjective norms, perceived behavioral control, intention to vaccinate CCS, CCS vaccination status, COVID‐19 health literacy, and frequency of COVID‐19 information‐seeking. Surveys were completed between May and June 2022 following approval for the emergency use of COVID‐19 vaccines among children aged ≥5 years in the U.S. Data were analyzed using unadjusted linear regressions and structural equation modeling. Results Participants were caregivers (n = 160, 87.5% biological mothers, 75.6% white/non‐Hispanic) of CCS (n = 160, 44.4% female, mean (M) = 12.5 years old, M = 8.0 years off treatment). 70.0% (n = 112) of caregivers and 53.8% (n = 86) of CCS received a COVID‐19 vaccine. Over one‐third (37.5%) of caregivers reported disagreement or indecision about future COVID‐19 vaccination for the CCS. Caregivers' intention (β = 0.962; standard error [S.E.] = 0.028; p
