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.
