Hepatitis B Vaccine for Adults
(HepB/HBV Vaccine – Adult Formulation)
Protects against:
- Hepatitis B Virus (HBV): Acute liver infection, chronic hepatitis, liver inflammation, jaundice, liver cancer (hepatocellular carcinoma), cirrhosis, liver failure, death
Who should get it:
- All unvaccinated adults – recommended for universal adult vaccination
- Healthcare workers, emergency responders, and laboratory personnel
- People with multiple sexual partners or sexually transmitted infections
- Men who have sex with men
- People who inject drugs or share needles
- Household contacts and sexual partners of HBV-infected individuals

Schedule:
Standard 3-dose series:
- Dose 1: Initial visit (Day 0)
- Dose 2: 1 month after first dose
- Dose 3: 6 months after first dose
Accelerated schedule (when faster protection needed):
- 0, 1, 2 months with booster at 12 months
Alternative 2-dose schedule (Heplisav-B for adults ≥18 years):
- Dose 1: Initial visit
- Dose 2: 1 month later
Why vaccinate:
- Hepatitis B is highly contagious – 50-100 times more infectious than HIV
- Prevents acute infection that can cause severe illness and hospitalization
- 5-10% of adults infected develop chronic, lifelong infection
- Chronic infection increases liver cancer risk by 100-fold
- No cure exists for chronic hepatitis B – prevention is the only defense
- Provides long-lasting, potentially lifelong immunity
- Safe and highly effective (>90-95% protection rate)
- Protects your family and sexual partners from transmission
- Required for many healthcare and international jobs
- Prevents need for costly lifelong monitoring and treatment
- Simple series provides decades of protection
- Well-tolerated with minimal side effects
Important note:
Adults receive a higher vaccine dose than infants and children. Completing the full series is essential for maximum protection – don’t skip doses. Blood tests can confirm immunity after vaccination if needed for occupational requirements. The vaccine is safe during pregnancy and breastfeeding. It’s never too late to get vaccinated – protection at any age is valuable.
