Limited data exists on sociodemographic differences in vaccination coverage against COVID-19 among adolescents. This study investigated the association of sociodemographic factors and vaccination coverage of adolescents aged 12 to 17 years over the period of the general vaccination recommendation in Stockholm County, Sweden. We conducted a population-based retrospective cross-sectional study of vaccine uptake of at least one dose of a COVID-19 vaccine up until 31 October 2022. We analysed vaccination coverage by sex, age group, underlying medical conditions, household socioeconomic factors, and vaccination status among adults in the household, using stratified analyses and multivariable modified Poisson regression models. The study cohort consisted of 166,634 adolescents out of which 70.3 % (n = 117,185) received at least one dose of a COVID-19 vaccine. In the fully adjusted model, the strongest predictor for not being vaccinated was if all adults in the household were unvaccinated (adjusted relative risk, aRR, 0.11, 95 % CI 0.10-0.12). Lower household education level and having both parents born outside Sweden were similarly negatively associated with vaccination coverage among adolescents. No association was observed between vaccination coverage and being an adolescent with an underlying medical condition (aRR 1.00, 95 % CI 0.99-1.02). Our results emphasise the necessity to address sociodemographic disparities and to engage adolescents at risk through targeted measures with particular emphasis in low-vaccination households in addition to households with lower education and non-Swedish origins in future vaccination program strategies.
