Children under 13 years old should get 2 doses of the chickenpox vaccine at these ages:
1st dose: 12 through 15 months of age
2nd dose: 4 through 6 years of age (may be given earlier, if at least 3 months after the 1st dose)
The second dose may be given at an earlier age if it is given at least 3 months after the first dose.
People 13 years of age and older (who have never had chickenpox and never received chickenpox vaccine) should get two doses at least 28 days apart.
MMRV is licensed for use in children 12 months to 12 years of age. Your child’s doctor can help you decide which vaccine to use.
However, pregnant women should wait to get the chickenpox vaccine until after they have given birth. Women should not get pregnant for 1 month after getting the chickenpox vaccine
Chickenpox vaccine is very effective. Two doses of the vaccine are about 98% effective at preventing chickenpox. Some people who are vaccinated against chickenpox may still get the disease. However, it is usually milder with fewer skin blisters and little or no fever.
