Hepatitis B is also contagious. It’s just that compared to patients with major hepatitis B, the viral content of minor triplets is relatively low, so the contagiousness is relatively low compared to major triplets, but it’s still contagious. The best way to protect yourself is to get the hepatitis B vaccine, which can be given at the local CDC or community health center. The hepatitis B vaccine is usually given in three injections, the injection periods are 0, 1 and 6, and there are two types of vaccines, domestic and imported, which can be chosen voluntarily. One month after the hepatitis B vaccination, antibodies can be checked, and the presence of antibodies proves that there is protection. If there are no antibodies, an additional booster shot is needed to produce antibodies.
