Chicken Pox Vaccine

Protects against:
Chickenpox (Varicella-Zoster Virus – VZV): Highly contagious viral infection causing itchy blister-like rash, fever, fatigue, headache, skin infection, pneumonia, encephalitis (rare), and severe disease in infants, adults, and immunocompromised individuals.

Who should get it:

Children (Primary Group):

• All children 12 months and older

Also recommended for:

• Adolescents and adults who never had chickenpox or vaccination
• Healthcare workers without immunity
• Household contacts of immunocompromised individuals
• People at higher risk of exposure (teachers, caregivers)

Schedule:

2-dose series:

• Dose 1: 12–15 months of age
• Dose 2: 4–6 years of age

Catch-up schedule:

• If ≥13 years: 2 doses at least 4 weeks apart

Why vaccinate:

• Chickenpox spreads easily through airborne droplets and direct contact
• Protects against severe disease and hospitalization
• Reduces risk of secondary bacterial skin infections
• Over 90–95% effective after two doses
• Provides long-term protection
• Helps reduce future risk of Herpes Zoster (shingles)

Important note:
The varicella vaccine is safe and well tolerated, with mild side effects such as soreness at the injection site or mild rash in a small number of children. Two doses provide the best protection and are recommended for long-term immunity.
