Safety review: two outer membrane vesicle (OMV) vaccines against systemic Neisseria meningitidis serogroup B disease

摘要

MenBvac is an OMV vaccine against systemic serogroup B Neisseria meningitidis disease. MenBvac was developed for control of a B:15:P1.7,16 subtype epidemic in Norway and administered to 180,000 subjects in 28 clinical studies. MeNZB, a daughter vaccine of MenBvac, was developed for a clonal B:4:P1.7b,4 epidemic in New Zealand and administered to 1 million people <20 years. The vaccines were similar regarding reactogenicity profile. Serious adverse events (SAEs) in general and particularly neurologic SAEs were very rare. Despite frequently reported local reactions and fever in those under 5 years, these OMV-based vaccines containing 25 microg antigen can be considered safe for use in all age groups.
