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

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.

MenB disease, a type of meningitis, is a serious and life-threatening illness. The US Centers for Disease Control and Prevention (CDC) recommends that 16­23-year-olds get a MenB vaccine after talking with their healthcare provider and deciding it is the right choice. As of 2021, only about 3 in 10 17-year-olds had received a MenB vaccine. In this study, we used an online survey to learn about parents of older teens' (16­18-years-old) and young adults' (19­23-years-old) awareness, thoughts, and practices related to meningitis and the MenB vaccine. Parents of non-vaccinated teens, and non-vaccinated young adults, had a lower awareness of the causes, risks, and symptoms of meningitis, and the MenB vaccine. In addition, most parents thought the impact of meningitis would be severe, compared with young adults who thought it would be less severe. Most participants were also not aware of their role in deciding if they or their child should be vaccinated against MenB. However, most showed a high interest in learning more about meningitis and the MenB vaccine. We also found that most teens and young adults who did receive the MenB vaccine received it right after talking about it with their healthcare provider. These findings show a clear opportunity to address gaps in awareness and thoughts about meningitis and MenB vaccination. Providing education and resources to parents, young adults, and healthcare providers could create more opportunities to discuss MenB vaccination and lead to more teens and young adults accessing vaccination and being protected against meningitis.

Expert Perspectives on the Vaccination of Individuals Who Are at Increased Risk of Meningococcal Disease Due to Medical Conditions: A Podcast.

Patients with functional or anatomic asplenia, including sickle cell anemia; complement component deficiency; or human immunodeficiency virus (HIV) infection have a significantly increased risk of developing meningococcal disease. The Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention (CDC) recommends vaccination with a quadrivalent meningococcal conjugate vaccine against serogroups A, C, W, and Y (MenACWY) for individuals 2 months of age or older who are diagnosed with functional or anatomic asplenia, complement component deficiency, or HIV infection. Vaccination with a meningococcal vaccine against serogroup B (MenB) is also recommended for individuals 10 years of age or older who are diagnosed with functional or anatomic asplenia or complement component deficiency. Despite these recommendations, recent studies have shown that vaccination coverage in these populations is low. In this podcast, the authors discuss the challenges for implementing vaccine recommendations for individuals with medical conditions at increased risk of developing meningococcal disease and discuss strategies to increase coverage. Suboptimal vaccination rates could be addressed by better educating healthcare providers about recommendations for MenACWY and MenB vaccines in individuals at increased risk, increasing awareness of low vaccination coverage, and tailoring the education to the needs of particular healthcare providers and their respective patient populations. Barriers to vaccination could also be removed by administering vaccines at alternative sites of care, bundling preventative services, and implementing vaccination reminder systems that are tied to immunization information systems.

Invasive meningococcal disease is rare, but serious. Some people are at increased risk because of their medical conditions, including: People without a working spleen People with reduced immune function due to conditions known as complement component deficiencies People living with human immunodeficiency virus (HIV) infection Vaccines are available to prevent meningococcal disease, and these vaccines are recommended for healthy young people as well as for people at increased risk. Studies have shown that a low proportion of people at increased risk has been vaccinated. Strategies are needed to make sure more people in these groups get vaccinated. We suggest educating healthcare providers about the recommended vaccines and making it easier for people to get vaccinated by, for example, providing vaccines in places they might visit more often than a doctor's office.
