Bexsero is indicated for active immunization to prevent invasive meningococcal disease caused by Neisseria meningitidis serogroup B in individuals aged 2 months to 25 years. The vaccine is particularly recommended for those at increased risk due to factors such as complement deficiencies, asplenia, or exposure during outbreaks.

Bexsero is a recombinant protein-based (non-live) vaccine that contains multiple antigenic components derived from the meningococcal B bacterium. By stimulating the immune system to produce antibodies against these bacterial proteins, the vaccine helps the body recognize and fight the pathogen if exposure occurs.

Common side effects may include pain at the injection site, fever, and irritability in children. As with all vaccines, there is a risk of allergic reactions. Bexsero does not protect against other meningococcal serogroups or other causes of meningitis. Vaccination schedules vary based on age and risk factors, and should be determined by a healthcare provider.
