Is there a limit to the number of MMR vaccinations an individual can receive?
A. There is no limit to the number of MMR vaccinations an individual can receive. The risk of adverse reactions falls with increasing number of doses of MMR (unlike inactivated vaccines such as tetanus) so the benefit of ensuring protection outweighs any risk of an additional dose of MMR. If an individual cannot recall whether (a) they have received MMR (or whether this was MR or single vaccines) or (b) the exact number of vaccinations they should receive additional MMR up to a total of two documented vaccinations, at least one month apart.
