Objectives: To examine the association between parents' influenza vaccination and their children's coronavirus disease 2019 (COVID-19) vaccination status.
Methods: Participants included father-mother dyads from Fathers & Families, a cohort of fathers and their co-parents living in the United States. Parents' influenza vaccination status and children's COVID-19 vaccination status were reported from June 2022-July 2023. Logistic regression was used to examine the association between parental influenza vaccination (both parents vs. neither parent vs. mother only vs. father only vaccinated) and child COVID-19 vaccination (received at least 1 vs. 0 doses). Models were adjusted for recruitment site, income, parent education, child race/ethnicity, child age, and childcare enrollment. Inverse probability weighting was used to account for selection bias into the father-mother dyad sample.
Results: Children were predominately non-Hispanic White (56 %) and aged 3-5 years (62 %). In most households, both parents (64 %) received the influenza vaccine and half (53 %) of children received the COVID-19 vaccine. One-in-four fathers (23 %) lacked knowledge about their child's COVID-19 vaccination eligibility. Compared to children with two unvaccinated parents, having only their father (adjusted odds ratio [AOR] = 2.84, 95 % confidence interval [CI]: 1.52-5.36), only their mother (AOR = 4.04, 95 % CI: 2.16-7.68), and both parents (AOR = 10.33, 95 % CI: 6.29-17.53) vaccinated against influenza was associated with higher odds of children receiving the COVID-19 vaccine.
Conclusions: Father and mother influenza vaccination is associated with child COVID-19 vaccination. Given many fathers were unaware their child was eligible for the COVID-19 vaccine, it is critical to tailor vaccine messaging for fathers.
