In the United States, meningococcal serogroup A, C, W, and Y (MenACWY) vaccines and serogroup B (MenB) vaccines are used to prevent IMD among adolescents. GlaxoSmithKline has developed a new pentavalent (MenABCWY) vaccine, covering all five serogroups: A, B, C, W, and Y, with licensure in spring 2025.

We used a lifetime analytic horizon to evaluate outcomes that extend beyond this period, including costs and quality-adjusted life years due to sequelae.

Hence, a tremendous effort is being made globally to develop next generation COVID-19 vaccines, which are capable of inducing a robust mucosal immune response in addition to a strong systemic cellular and humoral immune response. Mucosal COVID-19 vaccines have been evaluated successfully in preclinical and clinical trials, in which protection against SARS-CoV-2 infection has been demonstrated. This protective efficacy was associated with the upregulation of secretory IgA antibodies and the maturation of tissue-resident memory cells in the respiratory tract, which, together with an induced systemic immune response, significantly reduced viral replication and transmission in animal models. However, only five active mucosal vaccines (plus one ‘passive’ vaccine) have received approval for human use and robust data on their efficacy in inducing mucosal immune responses in humans and in blocking infection and transmission are missing. This highlights the importance of expanded research in this field.

However, most faith-based interventions in this field have been conducted on individual faiths, in isolation from other faiths, and have not explored the potential for active collaboration among faith-based groups. To address this gap, we conducted a study that aimed to inform the development of interfaith-based interventions to enhance vaccine acceptance. We conducted six focus groups, two semi-structured interviews and an interfaith co-design workshop, in community, online and University settings in London. Participants were from the Islamic, Christian, Jewish, Hindu and Sikh faiths. Interviews, focus groups and the workshop were transcribed verbatim and analysed using inductive reflective thematic analysis. We found that although there were some potential barriers to vaccine uptake due to religious beliefs, religion was a facilitator of vaccine uptake via the emphasis on protecting oneself and one's community and saving lives. However, embedded barriers in religious communities were related to mistrust, feelings of stigma and blame and tokenistic engagement. Key required interventions identified by participants were (i) training faith leaders to enable them to provide tailored messages to their communities, (ii) involving faith-based communities early in the process to enable them to feel included, rather than only approaching them once they were deemed hesitant, and (iii) vaccination messages delivered by groups of leaders from different faiths, so that they are all ‘singing from the same hymn sheet’.
