Awareness, attitudes, and practices on meningococcal serogroup B vaccination in the United States among parents of older adolescents and among young adults

Abstract

Objective Meningococcal serogroup B (MenB) vaccination is recommended by the Advisory Committee on Immunization Practices (ACIP) for adolescents and young adults 16–23-years-old under shared clinical decision-making (SCDM). However, MenB vaccination coverage in this population remains low in the United States (US). We investigated the awareness, attitudes, and practices regarding MenB disease and vaccination among parents of 16–18-year-old older adolescents and among 19–23-year-old young adults. Methods An online survey was conducted in September–October 2022 among parents of older adolescents and among young adults recruited from a US-based patient panel. Results There were 606 total participants, including parents of MenB-vaccinated (n = 151) and non-vaccinated (n = 154) adolescents, and also MenB-vaccinated (n = 150) and non-vaccinated (n = 151) young adults. Non-vaccinated cohorts reported low awareness of MenB disease (58.3–67.5%) and vaccination (49.7–61.0%), though awareness was higher among non-vaccinated parents. However, all cohorts reported high interest in learning more about MenB disease and vaccination. Vaccinated cohorts relied on primary care providers (PCPs) to initiate MenB vaccination conversation and had a low awareness of SCDM at 35.1–45.3%, though those aware of SCDM were more likely to participate in decision-making. Barriers to MenB vaccination included lack of PCP recommendation, vaccine side effects, and uncertainty about vaccination need. Conclusions There are gaps in awareness of MenB disease, vaccination, and SCDM among parents and patients in the US, resulting in missed opportunities for discussing and administering MenB vaccination. Targeted education on MenB and vaccination recommendations may increase these opportunities and improve MenB vaccination awareness and initiation.
