may be given to children from 1 through 12 years of age to protect them from these four diseases.

Two doses of MMRV vaccine are recommended:
The first dose at 12 through 15 months of age
The second dose at 4 through 6 years of age

These are recommended ages. But children can get the second dose up through 12 years as long as it is at least 3 months after the first dose.

Anyone 13 or older who needs protection from these diseases should get MMR and varicella vaccines as separate shots.

MMRV may be given at the same time as other vaccines.
