In brief: Depends

The routine in the US is one dose at age 1 yr and again at 4-5.
It is never repeated unless a prenatal workup shows a low protection level. If you never got it in childhood, it would be reasonable to do 2 doses at least a month apart to be sure adequate response was obtained. Some teens or adults note some transient joint pain during the weeks following the vaccine.
