After receiving the hepatitis B antibody shot, will I get infected from eating food that was previously eaten by someone with hepatitis B?

Receiving antibodies usually refers to developing antibodies after getting the hepatitis B vaccine. In this case, eating food previously consumed by someone with hepatitis B generally will not lead to infection. The details are as follows:

After receiving the hepatitis B vaccine, the body typically produces antibodies that protect against hepatitis B virus (HBV) invasion. Therefore, consuming food eaten by a person with hepatitis B usually does not result in infection, as the antibodies will eliminate any HBV entering the body and maintain health. Hepatitis B virus is primarily transmitted through blood, sexual contact, and mother-to-child transmission. The risk of contracting HBV through oral contact is relatively low, but there remains a certain level of infection risk. Thus, it is recommended to actively receive the hepatitis B vaccine for more comprehensive protection.

It should be noted that antibodies developed after hepatitis B vaccination are not lifelong. Individuals are advised to regularly check liver function and monitor antibody levels. If antibody levels decline, timely booster doses of the hepatitis B vaccine should be administered to ensure continued effectiveness of prevention.
