What is Varivax?
Varivax is a vaccine approved by the U.S. Food and Drug Administration (FDA) to prevent chicken pox (also known as primary varicella infection) in people 12 months of age and older. Chicken pox is an opportunistic infection. An opportunistic infection is an infection that occurs more frequently or is more severe in people with weakened immune systems—such as those infected with HIV—than in people with healthy immune systems.
The Guidelines for the Prevention and Treatment of Opportunistic Infections in HIV-Infected Adults and Adolescents
, prepared by the Centers for Disease Control and Prevention (CDC), the National Institutes of Health (NIH), and the HIV Medicine Association of the Infectious Diseases Society of America (IDSA-HIVMA), includes recommendations on the use of Varivax in HIV-infected individuals.
What should I tell my health care provider before receiving Varivax?
Before receiving Varivax, tell your health care provider:
- If you are allergic to gelatin, neomycin, any other ingredients in Varivax, or any medicines. Tell your health care provider if you have ever had any reactions to a previous dose of the vaccine or to any other varicella virus vaccines.
- About any medical conditions you have or have had, for example, diabetes or liver problems.
- If you are pregnant or plan to become pregnant. Whether Varivax can harm an unborn baby is unknown. Varivax should not be given to pregnant women. And pregnancy should be avoided for 3 months after vaccination.
- If you are breastfeeding or plan to breastfeed. Do not breastfeed if you are infected with HIV.
- About other prescription and nonprescription medicines, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Ask your health care provider if there are interactions between Varivax and the medicines you take.
