Brief summary
This study is a prospective observational cohort study in males and females, investigating the immune response in people vaccinated with the Neisseria meningitidis serogroup B (MenB) vaccine 4CMenB. Participants will receive 2 doses of 4CMenB vaccine 2 months apart by intramuscular injection. Gonorrhoea-specific immune responses will be measured to characterise possible mechanisms of vaccine-induced protection against gonorrhoea and to identify immunodominant antigens in 4CMenB and potential future gonorrhoea vaccine-candidates.
