The CDC recommends that children under 13 years get two doses of the chickenpox vaccine: one between the ages of 12 months and 15 months, and the second dose between the ages of 4 and 6 years.
People aged 13 and older who've never had chickenpox or the vaccine should get two doses, at least 28 days apart, the CDC says.
