Is it possible for an adult of age 24 to need the meningococcal vaccine?

Yes. If the 24 year old is attending college or graduate school, especially if living in a dormitory, and hasn't had a meningitis vaccine after the age of 16, this would be necessary. Other possible reasons would be: having an immune system problem and certain travel.
