How high is the percent am i covered after having the meningitis shot?

Which vaccine & when: There are 3 vaccines that we consider meningitis vaccines, hemophyllis influenza type b, pneumococcus & meningococcus. Most adults get the meningococcus, which covers for most of the strains involved in meningitis but not all. It provide relatively good antibody production that is considered protective for about 5 years before a booster would be helpful if regular exposure is likely.
