Chickenpox (Varicella) Vaccine
The chickenpox (varicella) vaccine is a highly effective, two-dose series that prevents nearly all cases of severe disease, typically administered at ages 12–15 months and 4–6 years.
It uses a live, weakened virus to provide long-lasting protection, reducing overall infection rates by 90%. It is recommended for children, teenagers, and adults without immunity.
Two doses are90% effective at preventing infection and over 95% effective at preventing severe disease.
Dosage Schedule: Children usually receive the first dose at 12–15 months and the second at 4–6 years.
Unvaccinated adolescents and adults should receive two doses, at least 28 days apart.
Vaccine Types: The primary vaccine is Varivax® (varicella-only).
The ProQuad® (MMRV) vaccine combines protection against measles, mumps, rubella, and chickenpox.
Recommended for children, healthcare workers, teachers, childcare employees, international travelers, and non-pregnant women of childbearing age.

Pregnant women, individuals with severe allergies to gelatin or neomycin, and people with compromised immune systems from cancer, HIV, or immunosuppressant medications should not receive the vaccine.
Side Effects: Generally mild, including pain, redness, or swelling at the injection site, fever, or mild rash.
