Hepatitis B Vaccine (rDNA) + Aluminium Hydroxide + Thiomersal

Introduction

Hepatitis B Vaccine (rDNA) + Aluminium Hydroxide + Thiomersal is a combination used for immunization against Hepatitis B infection. The recombinant DNA (rDNA) vaccine generates immunity by producing protective antibodies. Aluminium Hydroxide acts as an adjuvant, enhancing the immune response, while Thiomersal is a preservative that maintains vaccine stability. This combination is widely administered to newborns, children, and adults to prevent liver infection caused by the Hepatitis B virus (HBV).

Uses of Hepatitis B Vaccine (rDNA) + Aluminium Hydroxide + Thiomersal

• Prevention of Hepatitis B virus infection
• Recommended for all infants as part of immunization schedule
• Used for healthcare workers at risk of exposure
• Advised for individuals with chronic liver disease
• Given before certain medical procedures (e.g., dialysis)

How Hepatitis B Vaccine (rDNA) + Aluminium Hydroxide + Thiomersal Works

The vaccine contains a genetically engineered form of the Hepatitis B surface antigen (rDNA) that stimulates the immune system to produce antibodies. Aluminium Hydroxide boosts this immune response, while Thiomersal prevents contamination. Together, they offer long-lasting protection against HBV infection.
