MMR Vaccine Guidelines
Depending on a person's age and vaccination history, MMR (officially known as M-M-R® II) can be given in one or two doses. According to the standard MMR vaccine guidelines, children are typically given the vaccination in two doses. In most cases, the first injection is given when the child is between 12 and 15 months of age, and the second injection is given just before the child starts elementary school.
In some cases, adults may also need to receive this vaccine -- for example, if they cannot provide documentation of previous vaccination. The dosing guidelines call for at least one dosage of MMR in these situations. Occasionally, a second shot may be required.
