Varivax Indications/Uses

VARIVAX Refrigerated is indicated for vaccination against varicella in individuals 12 months of age and older.
Revaccination: The duration of protection of VARIVAX Refrigerated is unknown at present and the need for booster doses is not defined. However, a boost in antibody levels has been observed in vaccinees following exposure to wild-type varicella as well as following a booster dose of varicella virus vaccine live (Oka/Merck) [hereafter referred to as varicella vaccine (Oka/Merck)] administered four to six years postvaccination.
In a highly vaccinated population, immunity for some individuals may wane due to lack of exposure to wild-type varicella as a result of shifting epidemiology. Post-marketing surveillance studies are ongoing to evaluate the need and timing for booster vaccination.
Vaccination with VARIVAX Refrigerated may not result in protection of all healthy, susceptible children, adolescents, and adults (see Pharmacology under ACTIONS).
