The imported hepatitis B vaccine is mostly a drug that produces antibodies with one injection, but its price is more expensive, usually ranging from 200-500 yuan for one. The domestic hepatitis B vaccine requires about 1-3 injections, especially in the first injection of hepatitis B vaccine, the patient needs to be injected on the same day. In addition, the second injection will be given one month after the injection, and the third injection will be given at the end of six months. After the hepatitis B surface antibody is produced, it has a beneficial effect on the organism and is immune to chronic viral hepatitis B. Patients generally do not get chronic viral hepatitis B. Whether the patient is injected with imported hepatitis B vaccine or domestic hepatitis B vaccine, the result is that hepatitis B surface antibody needs to be produced after the vaccination. It is necessary for the patient to have his blood drawn and checked for hepatitis B triple system one month after the last injection of the vaccine to see if the patient is positive for hepatitis B surface antibody.
