Hepatitis B vaccine is non-responsive when given during the incubation period. Hepatitis B vaccination requires one month after the injection is completed before antibodies are formed. If you are already infected with the hepatitis B virus, the hepatitis B vaccination will not make your body’s immunity stronger. The incubation period of hepatitis B virus is usually 6 weeks to 6 months. During this period, if the body has strong resistance, the virus will be cleared by the body’s immune system. However, if the body’s immunity is weak, it will usually result in hepatitis B virus infection. Therefore, the hepatitis B vaccine may also be ineffective if it can be administered after the incubation period. When found infected with hepatitis B virus, must be actively treated. In the treatment at the same time should also pay attention to the daily diet, usually do not eat spicy and stimulating food, to develop good habits, pay attention to rest time.
