What type of vaccine is used for hepatitis B?

• A. A recombinant vaccine
• B. A live attenuated vaccine
• C. An inactivated vaccine
• D. A polysaccharide vaccine

Answer: (A)

The correct answer is that hepatitis B is prevented using a recombinant vaccine. This type of vaccine is developed by inserting a gene that encodes a protein from the hepatitis B virus into yeast or another expression system. The yeast then produces the viral protein, which is harvested and purified to create the vaccine. This method allows for a safe and effective way to stimulate an immune response without using the live virus itself. Recombinant vaccines generate specific immunity against the hepatitis B virus by triggering the body’s immune system to recognize and target the virus if encountered in the future. This is particularly important for hepatitis B, as it can lead to chronic liver disease and other serious health issues. In contrast, live attenuated vaccines use weakened forms of the virus, which is not the case for the hepatitis B vaccine. Inactivated vaccines consist of killed pathogens, while polysaccharide vaccines are made from carbohydrate components of the pathogen, neither of which applies to hepatitis B. Therefore, the recombinant approach is the most suitable and effective method for vaccination against hepatic B.
