Vaccines can help patients avoid infection of the disease virus and avoid the deterioration of the disease. Therefore, patients need to be vaccinated in time to avoid damage to liver health. When injecting hepatitis B vaccine, patients need to pay attention to the time of vaccination, and inoculation according to a fixed time will have a good effect. In addition, it is necessary to pay attention to local hygiene after vaccination to avoid infection.

　　 I believe many people were Hepatitis B vaccine has been injected, and even some patients have been injected with hepatitis B antibody in college. If the patient has not been vaccinated, there is a high probability that he will get hepatitis B disease, resulting in liver health damage. So what are the precautions for hepatitis B vaccine?

　　Patients need to pay attention to the time when they are injected with hepatitis B vaccine. Generally, the newborn needs to be vaccinated as soon as possible after birth. Generally, an intramuscular injection is performed within eight hours of birth. The injection site is in the deltoid muscle of the upper arm of the child. The second injection is given one month later. Six months later, the third injection was given. Three injections of vaccine after birth are considered complete. And before the vaccine is injected, patients need to be tested to avoid allergic reactions.
　　Second, pay attention to local hygiene
　　After the vaccine is injected, it is necessary to maintain the local hygiene of the injection site and maintain good hygiene to avoid the deterioration of the disease. In addition, three days after the vaccine injection, the patient should try not to wash it, and also avoid local infection caused by scratching the wound.
　　Three items that should not be vaccinated
　　 Not all people can be vaccinated against hepatitis B. Some patients with fever, severe infections, or patients with other serious diseases, He cannot be vaccinated against hepatitis B, so he needs to be vaccinated after the disease has healed. In addition, the hepatitis B vaccine cannot be vaccinated with other vaccines at the same time. For example, the hepatitis B vaccine and the measles vaccine will be vaccinated at the same time, which will reduce the effectiveness of the measles vaccine, so the two different vaccines are best to be vaccinated separately.
　　Four, check before vaccination
　　 Some of the antibodies in the adult body have failed, so before vaccination, you need to check the body, test HBV, check out the index. If the patient already has an infection, then the patient needs to be vaccinated after the infection is cured.
