•COVID-19 vaccination among adolescents varied with immigrant background and age.•There was great variation in vaccination rates by country background.•Household income and parental education were positively associated with vaccination.•Sociodemographic associations were stronger among the younger adolescents. Lower COVID-19 vaccination rates have been observed among some adult immigrant populations in Norway, and there appears to be an association with sociodemographic factors. However, knowledge is lacking on the distribution of vaccination rates and role of sociodemographic factors among adolescents. This study aims to describe COVID-19 vaccination rates among adolescents according to immigrant background, household income, and parental education. In this nationwide registry study, we analyzed individual-level data on adolescents (12–17 years) from the Norwegian Emergency preparedness register for COVID-19 until September 15th, 2022. We estimated incidence rate ratios (IRR) for receiving at least one COVID-19 vaccine dose by country background, household income and parental education, using Poisson regression, adjusting for age, sex, and county. The sample comprised 384,815 adolescents. Foreign-born and Norwegian-born with foreign-born parents, had lower vaccination rates (57 % and 58 %) compared to adolescents with at least one Norwegian-born parent (84 %). Vaccination rates by country background varied from 88 % (Vietnam) to 31 % (Russia). Variation and associations by country background, household income, and parental education were greater among 12–15-year-olds than 16–17-year-olds. Household income and parental education were positively associated with vaccination. Compared to the lowest income and education category, IRRs for household income ranged from 1.07 (95 % CI 1.06–1.09) to 1.31 (95 % CI 1.29–1.33) among 12–15-year-olds, and 1.06 (95 % CI 1.04–1.07) to 1.17 (95 % CI 1.15–1.18) among 16–17-year-olds. For parental education, from IRR 1.08 (95 % CI 1.06–1.09) to 1.18 (95 % CI 1.17–1.20) among 12–15-year-olds, and 1.05 (95 % CI 1.04–1.07) to 1.09 (95 % CI 1.07–1.10) among 16–17-year-olds. COVID-19 vaccination rates varied by immigrant background and age group, with lower rates especially among adolescents with background from Eastern Europe and among younger adolescents. Household income and parental education were positively associated with vaccination rates. Our results may help target measures to increase vaccination rates among adolescents.
