Varicella vaccine is recommended for all healthy adolescents and adults who have not received the vaccine and have no confirmed history of chickenpox (SOR A).
Two doses are required, given at least 4 weeks apart. Particular attention should be given to immunizing women of reproductive age, international travelers, and close contacts of immunosuppressed patients.
However, because the vaccine is a live virus, women of reproductive age should be counseled to delay conception for at least a month after receiving the second dose of the vaccine, and pregnant women should not receive the vaccine until after delivery.
