The main purpose of this study is to evaluate the immune response and safety of a booster dose of the meningococcal group B vaccine, rMenB+OMV NZ (also known as Bexsero), in adolescents and young adults aged 10 to 20 years. This study focuses on individuals who were first vaccinated with rMenB+OMV NZ as infants. The primary hypothesis is that a booster dose of the vaccine will elicit a stronger immune response in these primed individuals compared to those who have never received any group B meningococcal vaccine, referred to as 'nave' participants.
