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.

Abstract
In the United States (US), meningococcal serogroup B (MenB) vaccination has been recommended for 16-23-year-olds (preferably 16-18 years) based on shared clinical decision-making since 2015. MenB vaccine coverage (≥1 dose) by age 17 years has been reported, but initiation at older ages and by insurance type is unknown. In this retrospective cohort study, MarketScan claims data were analyzed to assess MenB vaccine series initiation (i.e. receipt of a first dose) during 2017-2020 among US commercially insured and Medicaid-covered individuals aged 16-18 and 19-23 years. Kaplan-Meier curves were generated to estimate series initiation at various times from index (latest of 1/1/2017 or 16th/19th birthday, depending on the cohort). Multivariable analyses were conducted to identify factors associated with series initiation. Among 1,450,354 Commercial and 1,140,977 Medicaid 16-18-year-olds, MenB vaccine series initiation rates within 3 years of each person's first eligibility were estimated to be 33% and 20%, respectively; among 1,857,628 Commercial and 747,483 Medicaid 19-23-year-olds, 3% and 1%, respectively. Factors identified to be significantly associated with increased likelihood of initiating a MenB vaccine series included co-administration of meningococcal serogroups ACWY (MenACWY) vaccine, younger age, female sex, nonwhite race (Medicaid only), New England or Middle Atlantic location (Commercial only), urban residence, and previous influenza vaccination. MenB vaccine series initiation among the studied US adolescents and young adults was low. There is a need for continued efforts to better understand barriers to the uptake of vaccines that are recommended based on shared clinical decision-making.

Abstract
BACKGROUND Invasive meningococcal disease (IMD) is a severe infectious disease. Although effective preventive and therapeutical strategies are available, the fatality rate remains high in the general population, with an occurrence of meningococcal-related severe sequelae involving 10-20% of survivors. Given the crucial role of general practitioners in recognizing and preventing IMD and its related sequelae, we aim to assess the burden of these conditions in primary care. METHODS Using an Italian primary care database, the incidence rate of IMD was calculated in the period 2000-2019 by capturing the first diagnosis registered during follow-up. As far as meningococcal-related sequelae are concerned, we identified and clinically evaluated each potential sequela during the first 3 months, from 3 to 12 months, and up to 36 months. RESULTS Among 508 patients diagnosed with IMD, 403 (incidence rate: 0.24 per 10,000 person-years) comprised those diagnosed with IMD in patients aged 15 years or older. We ascertained 104 sequelae (20.4%); 76% of them occurred in those aged 25 or older; 42, 27, and 35 were assessed as short-, medium-, or long-term sequelae, respectively. Overall, 4.7% of IMD patients reported physical sequelae, while 12.2% and 5.7% of patients reported neurological and psychological sequelae, respectively. CONCLUSION Our study showed that a substantial proportion of IMD and related sequelae occur in individuals aged over 25, with a non-negligible burden for healthcare systems. As for the paediatric population, effective communication on the relevance of meningococcal vaccination in adults should be proficiently fostered.

Determinants of Meningococcal Vaccination Coverage and Adherence: A Targeted Literature Review Supporting a 16-year-old Healthcare Visit. Infect Dis Ther 2023; 12:1265-1282. [PMID: 37219795 DOI: 10.1007/s40121-023-00793-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Accepted: 03/22/2023] [Indexed: 05/24/2023] Open
Abstract
We conducted a targeted literature review to understand the determinants of meningococcal serogroups A, C, W, and Y (MenACWY) and meningococcal serogroup B (MenB) vaccination coverage and adherence to vaccination schedules in the USA, and to identify evidence to support improvement of MenACWY and MenB vaccination coverage and adherence in older adolescents. Sources published since 2011 were considered, with sources published since 2015 given preference. Out of 2355 citations screened, 47 (46 studies) were selected for inclusion. Determinants of coverage and adherence ranging from patient-level sociodemographic factors to policy-level factors were identified. Four determinants identified were associated with improved coverage and adherence: (1) well-child, preventive, or vaccination-only appointments (particularly for older adolescents); (2) provider-initiated, provider-driven vaccine recommendations; (3) provider education about meningococcal disease and vaccine recommendations; and (4) state-level school-entry immunization policies. This robust review of the literature sheds light on the continued low MenACWY and MenB vaccination coverage and adherence among older adolescents (16-23 years of age) compared with that of younger adolescents (11-15 years of age) in the USA. The evidence supports a renewed call to action by local and national health authorities and medical organizations urging healthcare professionals to implement a healthcare visit for 16-year-olds and focus on vaccination as a key component of the visit.

Abstract
Vaccines remain a fundamental intervention for preventing illness and death. In the United States, suboptimal vaccine uptake in adolescents and young adults has been observed for meningococcal conjugate (MenACWY) and serogroup B meningococcal (MenB) vaccines, particularly among marginalized communities, despite current recommendations by the Advisory Committee on Immunization Practices. A systematic literature search was conducted in the MEDLINE and MEDLINE In-Process, Embase, Cochrane, PsychInfo, and CINAHL databases to identify both drivers of, and barriers to, MenACWY and MenB vaccine uptake in adolescents and young adults. A total of 34 of 46 eligible studies that presented outcomes stratified by race/ethnicity, geography, and socioeconomic status were selected for review. Results showed MenACWY and MenB vaccination coverage in adolescents and young adults is impacted by racial/ethnic, socioeconomic, and geographic disparities. Gaps also exist in insurance for, or access to, these vaccines in adolescents and young adults. Moreover, there was variability in the understanding and implementation of the shared decision-making recommendations for the MenB vaccine. Disease awareness campaigns, increased clarity in accessing all meningococcal vaccines, and further research on the relationships between measures of marginalization and its impact on vaccine coverage in adolescents and young adults are needed to reduce the incidence of severe infections.

Abstract
OBJECTIVES Invasive meningococcal disease (IMD) is a life-threatening disease that can rapidly progress to death or leave survivors with severe, life-long sequelae. Five meningococcal serogroups (A, B, C, W and Y) account for nearly all IMD. Meningococcal serogroup distribution fluctuates over time across the world and age groups. Here, we consider the potential public health impact of a pentavalent MenABCWY vaccine developed to help further control meningococcal disease and improve immunisation rates. RESULTS The GSK MenABCWY vaccine combines the antigenic components of MenACWY-CRM (Menveo®) and 4CMenB (Bexsero®), building on a wide body of clinical experience and real-world evidence. Both approved vaccines have acceptable safety profiles, demonstrate immunogenicity, and are broadly used, including in national immunisation programmes in several countries. Since the advent of quadrivalent vaccines, public health in relation to IMD has improved, with a decline in the overall incidence of IMD and an increase in vaccine coverage. CONCLUSION A pentavalent MenABCWY has the potential to provide further public health benefits through practical, broad IMD protection programmes encompassing serogroups A, B, C, W and Y, and is currently in late-stage development.

Abstract
BACKGROUND In 2015, the Advisory Committee on Immunization Practices recommended Meningococcal B vaccination for healthy 16- to 23-year-olds based on shared clinical decision-making between the patient and the provider. There has been some confusion regarding how to implement this recommendation. METHODS Through discussions among the authors, a review of relevant literature, and consultation with vaccine experts, we developed educational materials for providers that included a patient handout to help initiate and guide conversations leading to shared clinical decision-making for the Meningococcal B vaccine. Materials were distributed to 88 health care providers who subsequently completed surveys to evaluate their impressions of the materials and the utility of the materials for clinical practice. RESULTS The survey results from the 88 providers revealed that they valued the materials; 93% percent indicated they would share these materials with colleagues, and 95% agreed or strongly agreed that they would share these materials with patient families. Responses to an open-ended question indicate that some providers initiated discussions regarding the Meningococcal B vaccine in ways that truncated conversation rather than encouraging a shared decision-making process. CONCLUSIONS Overall, the materials developed and implemented for this project support the initiation of, and help standardize provider conversations regarding, Meningococcal B vaccination for healthy adolescents.

Abstract
BACKGROUND In the United States, meningococcal serogroup B (MenB) vaccination is recommended for 16-23-year-olds based on shared clinical decision-making. We estimated series completion among individuals initiating MenB vaccination for the 2 available vaccines: MenB 4-component (MenB-4C, doses at 0 and ≥1 month) and MenB factor H binding protein (MenB-FHbp, doses at 0 and 6 months). METHODS This retrospective health insurance claims data analysis included 16-23-year-olds who initiated MenB vaccination (index date) during January 2017 to November 2018 (MarketScan Commercial Claims and Encounters Database) or January 2017 to September 2018 (MarketScan Multi-State Medicaid Database) and had continuous enrollment for ≥6 months before and ≥15 months after index. The main outcome was MenB vaccine series completion within 15 months. Among noncompleters, preventive care/well-child and vaccine administrative office visits were identified as potential missed opportunities for series completion. Robust Poisson regression models identified independent predictors of series completion. RESULTS In the Commercial (n = 156,080) and Medicaid (n = 57,082) populations, series completion was 56.7% and 44.7%, respectively, and was higher among those who initiated MenB-4C versus MenB-FHbp (61.1% versus 49.8% and 47.8% versus 33.9%, respectively; both P < 0.001). Among noncompleters, 40.2% and 34.7% of the Commercial and Medicaid populations, respectively, had ≥1 missed opportunity for series completion. Receipt of MenB-4C and younger age were independently associated with a higher probability of series completion. CONCLUSIONS Series completion rates were suboptimal but were higher among those who initiated MenB-4C. To maximize the benefits of MenB vaccination, interventions to improve completion and reduce missed opportunities should be implemented.
