The vaccine is typically referred to as one of the following names:
- Engerix-B
- Recombivax HB
- Heplisav-B
These three vaccines have been authorized for use, providing protection against the Hepatitis B virus.
Engerix-B
Engerix-B is one of the commonly used vaccines to prevent Hepatitis B. It contains a small portion of the virus protein that triggers an immune response without causing the disease itself. The immune response allows the body to develop immunity against Hepatitis B.
Engerix-B is administered as a series of injections, usually three doses over a span of six months. It is highly effective at providing long-lasting protection against the virus.
Recombivax HB
Recombivax HB is another well-known vaccine for Hepatitis B. It also contains a part of the virus protein to stimulate an immune response in the body.
Similar to Engerix-B, Recombivax HB is given in a series of injections. The standard immunization schedule involves three doses, with the second dose administered one month after the first, and the third dose given five months after the second.
Heplisav-B
Heplisav-B is a relatively newer addition to the Hepatitis B vaccine family. It is a two-dose series vaccine, meaning it requires two doses instead of three for complete immunization.
Heplisav-B has been approved for use in individuals aged 18 years and older. With an accelerated schedule, the second dose can be given as soon as one week after the first. This vaccine has shown high effectiveness in stimulating immune response and providing protection against Hepatitis B.
In conclusion, the names of the Hepatitis B vaccines commonly used are Engerix-B, Recombivax HB, and Heplisav-B. All of them are effective at preventing the Hepatitis B virus and are administered through a series of injections.
