Meningococcal B vaccination coverage among older adolescents in the United States

Abstract

Background: Serogroup B meningococcal (MenB) vaccination recommendations for adolescents in the United States (US) include routine vaccination for all individuals at increased risk and vaccination for individuals not at increased risk aged 16-23 years (preferred age 16-18 years) based on shared clinical decision-making. The two licensed MenB vaccines require administration of ≥2 doses.

Methods: This cross-sectional study analyzed 2017-2018 National Immunization Survey-Teen (NIS-Teen) data to evaluate ≥1 dose and ≥2 dose MenB vaccination coverage among adolescents aged 17 years. Multivariable logistic regression was used to further evaluate determinants of MenB vaccination.

Results: Nationally, MenB vaccination coverage among 17-year-olds increased from 14.5% in 2017 to 17.2% in 2018 for ≥1 dose and from 6.3% to 8.4% for ≥2 doses. MenB vaccination coverage (2017-2018) was the lowest in the South (≥1 dose: 14.6%; ≥2 doses: 6.3%) and highest in the Northeast region (18.3% and 9.3%), with variation observed by census division. Adolescents were more likely to have received ≥1 dose of MenB vaccine if they had any Medicaid insurance (odds ratio [OR], 1.77; 95% confidence interval [CI], 1.32-2.39) or had received human papillomavirus (OR, 1.94; 95% CI, 1.41-2.67) or meningococcal A, C, W, and Y (OR, 4.03; 95% CI, 2.92-5.56) vaccinations.

Conclusions: MenB first-dose coverage in the US is low, and even lower for a second dose, with regional variation. Being up to date with other routinely administered vaccines increased the likelihood of receiving MenB vaccination.
