Is meningococcal B vaccination needed in the post-COVID-19 world?

Neisseria meningitidis is the main cause of bacterial meningitis worldwide and is transmitted through respiratory secretions. Meningitis is a serious public health problema because of its high morbidity and mortality rates and the risk of causing epidemics. Although vaccines are available to prevent meningococcal disease, serogroup B infections are still challenging, given that many countries do not include meningococcal B vaccines in their national immunization programs. In addition, recent data suggests somewhat sustained N. meningitidis B infections during the COVID-19 pandemic and increasing levels of meningococcal disease after its control. These findings agree with previous observations indicating that respiratory viruses facilitate respiratory bacterial infections. This essay intends to present epidemiological data on meningococcal disease and discusses studies exploring why the prevention of bacterial and viral infections is an intricate subject.
