How long does the meningicoccal vaccine last?

Question

Is it a one time only shot?
What about pnuemococcus? One time only?

Answer 1

according to the cdc, meningococcus should be given only if going into a high risk area for that disease, and if one remains in the high risk area a booster should be given every two years.
pnuemococcus should be given to those most at risk from it, ie the elderly and immune compromised and a booster given every five years.
