MMR at 1 and 4 years
shot (or measles
shot) is indicated as a two dose series, given at least months apart after the age of 1 yo.
Standard is that its given after 1 yo and then again at 4 yo. Adults can receive it anytime if previously unvaccinated or proven non-immune. The m, m and r components no longer come as separate shots at all, and must be given together as mmr.
