The Advisory Committee on Immunization Practices (ACIP) and the American Academy of Pediatrics (AAP) now recommend 2 doses of this vaccine for all children. [30, 5, 31] After the first dose at age 12-15 months, the second should be administered at age 4-6 years. All persons who have received one dose at any time in the past should be offered a second dose. Two doses of the vaccine provide 98% protection against varicella and 100% protection against severe disease. [5] These children also have a lower incidence of breakthrough varicella. [28]
