- 1 mL for adults
🔬 Nature:
- Type: Recombinant subunit vaccine
- Form:
- Sterile suspension of purified HBsAg in buffered saline
- Adjuvanted with aluminum salts to enhance immune response
- Non-infectious and non-live – cannot cause disease
🌟 Advantages:
- Highly effective (95–98% seroconversion rate)

- Inform the provider if allergic reactions, fever, or other unusual symptoms occur after vaccination
- Keep the vaccination record/card safe for future reference
