Prevention

Hepatitis B infection can be prevented thanks to the creation of vaccines. According to the World Health Organization, the Hepatitis B vaccine offers 98-100% protection against hepatitis B infection. There are different ways vaccines induce the development of the body’s immune response towards a viral agent.

Some vaccines use dead microorganisms, while some inject attenuated viruses into the body. Only viral antigens and not the whole virus are used to trigger an immune response. All these processes have the same result, i.e., immune cells (antibodies) production against infectious agents.

There are 2-dose and 3-dose hepatitis B vaccines available. However, studies suggest that a two-dose vaccine (recombinant hepatitis B vaccine) is better than a three-dose vaccine.
