Who doesn't need to get the hepatitis B vaccine

The hepatitis B vaccine is effective in preventing hepatitis B virus, but not everyone is vaccinated against hepatitis B.

Who doesn't need to get the hepatitis B vaccine

There are two types of people who do not need to be vaccinated against hepatitis B, one is chronic hepatitis B patients and hepatitis B virus carriers, and the other is those who already have hepatitis B surface antibodies in the body. The purpose of vaccination against hepatitis B is to stimulate the body's immune response, produce hepatitis B surface antibodies, hepatitis B surface antibodies exist in the body, once hepatitis B virus appears, it can clear hepatitis B virus, prevent hepatitis B virus infection, and have immunity to hepatitis B virus.

If hepatitis B surface antibodies already exist in the body, it is usually not necessary to inject hepatitis B vaccine, or if hepatitis B virus is already present in the body, already a hepatitis B virus carrier or chronic hepatitis B patient, then it is not meaningful to inject hepatitis B vaccine. Therefore, there is no need for hepatitis B vaccination in both cases.

Strictly speaking, anyone who has not been infected with hepatitis B virus and has insufficient autoantibodies is a susceptible group and should be vaccinated against hepatitis B. After all, there are many hepatitis B carriers in China, and there is usually a great opportunity to contact hepatitis B patients, even if the spread of the virus is limited by transmission, generally will not get hepatitis B, but who can guarantee that their skin, mouth and other parts will not produce wounds? There is also no guarantee that the virus will not be transmitted to itself through the wound.
