About Varicella Virus Vaccine
Indications of Varicella Virus Vaccine
Established / Approved Use
Varicella Virus Vaccine is indicated for active immunization for the prevention of varicella (chickenpox) in healthy individuals 12 months of age and older who have no history of the disease and no evidence of immunity.
Guideline-Supported Uses
- Routine childhood immunization: a two-dose series given as part of the standard national/international immunization schedule.
- Catch-up vaccination: susceptible adolescents and adults who have not previously received Varicella Virus Vaccine or had confirmed varicella.
- Post-exposure prophylaxis: when given within 3-5 days of exposure to a case of varicella, Varicella Virus Vaccine can prevent or significantly modify (reduce severity of) the disease in susceptible contacts, per current public health guidance.
- Occupational and household-contact vaccination: susceptible healthcare workers, teachers, childcare staff, and household contacts of immunocompromised persons, to reduce transmission risk.
Varicella Virus Vaccine is not intended for treatment of active varicella or herpes zoster infection.

Frequently Asked Questions about Varicella Virus Vaccine
What is Varicella Virus Vaccine used for?
Varicella Virus Vaccine is used to actively immunize people 12 months of age and older against varicella (chickenpox), and can also reduce the severity of disease if given shortly after exposure.
How many doses of Varicella Virus Vaccine are needed?
Most people need two doses of Varicella Virus Vaccine for optimal, long-lasting protection - the exact interval depends on age; a single dose gives only partial protection.
Can Varicella Virus Vaccine be given during pregnancy?
No. Varicella Virus Vaccine is contraindicated in pregnancy because it is a live vaccine with a theoretical risk to the fetus; women should avoid pregnancy for at least one month after each dose and should discuss timing with their physician.
Is it safe to take aspirin after receiving Varicella Virus Vaccine?
Aspirin and other salicylate-containing medicines should be avoided for 6 weeks after Varicella Virus Vaccine because of a theoretical link between salicylates, varicella, and Reye's syndrome.
What are the common side effects of Varicella Virus Vaccine?
The most common effects are injection-site pain, redness or swelling, mild fever, and occasionally a mild rash appearing 5-26 days after vaccination. Serious reactions such as anaphylaxis are rare.
Who should not receive Varicella Virus Vaccine?
People with a severe allergy to a previous dose or to a vaccine component (such as gelatin or neomycin), pregnant women, people with active untreated tuberculosis, and people with severe immunodeficiency should not receive Varicella Virus Vaccine; consult a physician to confirm eligibility.
