Hepatitis A Vaccine – Havrix Junior
(Pediatric Hepatitis A Vaccine)
Protects against:
- Hepatitis A Virus (HAV): Acute liver infection, jaundice, severe fatigue, nausea, abdominal pain, liver failure (rare), prolonged illness lasting weeks to months
Who should get it:
Children (Primary Group):
- All children 12 months to 18 years
- Routine childhood immunization starting at age 1 year
- Children traveling to endemic areas
- Children with chronic liver disease
- Children in daycare settings
Also recommended for:
- Adolescents not previously vaccinated
- Children in communities with high hepatitis A rates

Schedule:
2-dose series:
- Dose 1: 12-23 months of age (or at time of first travel)
- Dose 2: 6-12 months after first dose (minimum 6 months apart)
For travel: First dose at least 2 weeks before departure
Why vaccinate:
- Highly contagious – spreads easily through contaminated food, water, and person-to-person contact
- Children often have mild/no symptoms but spread virus to vulnerable adults
- Prevents outbreaks in daycare and school settings
- Provides long-lasting, possibly lifelong immunity after 2 doses
- Protects before travel to high-risk regions (Asia, Africa, Latin America)
- Nearly 100% effective after complete series
- Safe with minimal side effects
- Prevents weeks of illness and school absence
- Protects family members from infection
- No specific treatment exists – prevention is essential
Important note:
Havrix Junior is specifically formulated for children (lower dose than adult formulation). Complete both doses for full protection. The vaccine is highly effective and safe – over 95% protection after 2 doses. Children are often silent spreaders of hepatitis A, making vaccination important for community protection. If traveling, vaccinate at least 2 weeks before departure for adequate immunity.
