Definition: The Hepatitis B vaccine, commonly known as Hepatitis B vaccine (Recombinant), is an immunization product used to prevent or reduce the risk of developing hepatitis B virus (HBV) infection, a viral disease characterized by symptoms such as nausea and vomiting, abdominal pain, diarrhea, jaundice, and fever. The Hepatitis B vaccine consists of a recombinant protein derived from blood plasma, which is produced in a laboratory. The recombinant protein contains the hemagglutinin (HA) and neuraminidase (NA) subunits, as well as other proteins that are essential for the immune response to HBV infection. The Hepatitis B vaccine is typically administered as an intramuscular or subcutaneous injection, but it may also be given by oral vaccination. The immunization schedule depends on the type of vaccine and the age of the recipient. In addition to preventing hepatitis B infection, the Hepatitis B vaccine has other health benefits. It can help reduce the risk of developing chronic liver disease and certain types of cancer, such as hepatocellular carcinoma. The specific details of how the Hepatitis B vaccine works vary by country or region, but it is generally administered through a series of injections over several months, with each injection containing the required amount of antigen to stimulate an immune response. The body may also produce antibodies against HBV after receiving the first vaccine dose, although these responses can be temporary. Overall, the Hepatitis B vaccine provides a powerful tool for protecting individuals from the harmful effects of hepatitis B infection and reducing the risk of other serious health conditions associated with this virus.
