Study of the Immune Response in the Elderly: Is It Necessary to Develop a Vaccine against Neisseria meningitidis for the Aged?

Abstract EN

Literature reports the association between aging and decline in the immune system function.

The elderly have a higher risk of developing infectious diseases and are often less responsive to vaccines that are effective in the young.

The case fatality rate of invasive meningococcal disease is higher in the elderly; therefore, vaccination for this population should be evaluated.

Although new vaccines have been developed against Neisseria meningitidis, there is still a need to evaluate a vaccine for those older than 60 years, as the currently licensed vaccines are not indicated for this population.
