🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This vaccine contains hepatitis B surface antigen produced by recombinant DNA technology. After injection, the antigen is taken up by antigen-presenting cells, which process and present it to T helper cells. This activates B cells to produce specific antibodies against the hepatitis B surface antigen. The aluminium hydroxide adjuvant enhances the immune response by creating a depot at the injection site and stimulating innate immune pathways. The resulting antibodies bind to the virus and prevent it from infecting liver cells. Memory B and T cells are also formed, providing long-term protection.
Mechanism Steps
💡 How to Take bevac vaccine
Strength: Injection: 10 mcg hepatitis B surface antigen + 0.25 mg aluminium hydroxide per dose.
Dosage Information
| Adult Dosage | The standard adult dose is 10 mcg of hepatitis B surface antigen combined with 0.25 mg of aluminium hydroxide, given as an intramuscular injection. The usual schedule is three doses: the first at a chosen date, the second one month later, and the third six months after the first. For certain high-risk groups, alternative schedules may be used. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | The same adult dose can be used in elderly patients, but the immune response may be lower. A doctor may check antibody levels after vaccination. |
| Renal Impairment | No dose adjustment is required for patients with renal impairment, but the immune response may be reduced in those with severe kidney disease. |
| Hepatic Impairment | No dose adjustment is required for patients with hepatic impairment. |
| Maximum Daily Dose | Not applicable. This vaccine is given as a single dose per scheduled visit. |
