Hepatitis B carriers are not eligible for hepatitis B vaccination. Hepatitis B vaccine is suitable for people who have not been infected with hepatitis B. Through vaccination, the body will produce hepatitis B surface antibody, so as to prevent the infection of hepatitis B virus. But hepatitis B carriers have already been infected with hepatitis B virus, hepatitis B vaccination is ineffective, and may even mutate the hepatitis B virus already contained in the body and aggravate the condition. Therefore, hepatitis B carriers cannot receive hepatitis B vaccine. Hepatitis B carriers should adhere to regular monitoring and review, usually every six months need to carry out liver ultrasound, liver elasticity test and HBV (viral hepatitis B) test. Once abnormal liver function is detected, viral therapy should be given immediately, and commonly used drugs include tenofovir and entecavir to avoid causing cirrhosis, liver cancer and other diseases. If Hepatitis B carriers experience symptoms such as loss of appetite, abdominal distension, generalized weakness, etc., it is considered that chronic viral hepatitis B may develop. It is recommended to go to the hospital for consultation, please do not self-medicate, and should be diagnosed and treated under the guidance of a doctor.
