HEPATITIS B VACCINE – TYPE OF VACCINE
- Hepatitis B Vaccine (HBV) is a purified surface antigen of hepatitis B virus.
- Fortunately, the cost of the vaccines has been declining and the cost may no longer be a consideration in the choice of the vaccine.
- The vaccine is very effective and gives 95% protection against hepatitis B virus infection.
- 2 types of vaccines are available:
o “Plasma derived vaccine” is made from the plasma of Hepatitis B positive carriers. Though, the vaccine is made from a “blood product”, the process of manufacture however makes it safe and effective.
o “Recombinant Vaccine” is made by genetic engineering and has the advantage of not being made from a “blood product”. It is equally safe and effective.
