Test results of Hepatitis B V are required before taking Hepatitis B booster shot.
Hepatitis B booster shot is suitable for people without hepatitis B infection (i.e. hepatitis B surface antigen negative) and hepatitis B surface antibody <10mIU/mL, used to increase the level of hepatitis B surface antibody within a short period of time to prevent hepatitis B virus infection. Hepatitis B patients do not need to take Hepatitis B booster shots, so it is often necessary to take Hepatitis B pentameter test before vaccination of Hepatitis B booster shots.
Hepatitis B vaccine is a national program for immunization, a total of three injections are required, respectively, at 0, 1, 6 months, emphasizing the first injection in time and the whole vaccination, the protection effect is better for those who have antibody response after hepatitis B vaccination, the general population does not need to be booster vaccination for hepatitis B, and the World Health Organization does not recommend booster vaccination for hepatitis B. If you have contact with patients with hepatitis B, you do not need to take booster vaccine for hepatitis B, therefore, it is often necessary to take the test of hepatitis B 5 before vaccination.
If there is a risk of exposure to hepatitis B patients and the titer of hepatitis B surface antibody is low, hepatitis B booster shot can be given to increase resistance, but it should be carried out in regular medical institutions.
It is recommended that patients be vaccinated in a standardized manner under the guidance of a medical professional.
