Ever since the Covid-19 vaccine became available, vaccinations in adolescents lagged behind adults. Whether adolescent vaccination rates were higher in states with “Minor Consent” policies remains unknown.

We accessed adolescent (aged 12-17) county-level vaccine administration data from the CDC (12/2020-05/2023) Our outcomes were Covid-19 vaccination counts for (1) initial dose, (2) completed series doses, (3) booster doses. Panel Poisson regression models with state and time random effects, seasonal fixed-effects, log-population offsets, and adult vaccination rates were estimated to calculate incidence rate ratios (IRR), testing the association between residing in a state with a Minor Consent policy and Covid-19 vaccine uptake.

Overall, for the initial dose and complete series, there was no difference in adolescent Covid-19 vaccination between states with or without Minor Consent policies. However, we found that Minor Consent policies were associated with lower Covid-19 booster doses (IRR = 0.582; 95% CI: 0.409, 0.828; p = 0.0026). This association was not found in urban (IRR = 0.867; CI = 0.722, 1.043; p = 0.1295), but only in rural counties (IRR 0.541; CI 0.401, 0.730; p < 0.0001).

Minor Consent policies were not associated with higher adolescent Covid-19 vaccination. Rather, we found that Minor Consent policies were associated with lower adolescent vaccination for booster doses in rural counties. Despite minimal evidence of impact, states continue to implement Minor Consent vaccination policies. Future research on the topic should investigate, not just other vaccines, but how Minor Consent policies impact parental trust in public health more broadly.
