Hepatitis B vaccine booster shots are generally divided into two kinds, one is 20ug and the other is 60ug, and the injection methods of the two kinds of booster shots are different.
For newborns or people who have never received hepatitis B vaccine, it is possible to receive 20ug of hepatitis B vaccine, but it is necessary to receive three injections, usually one each at 0, 1, and 6 months of age, which can achieve a better protective effect.
For those who have been vaccinated against hepatitis B and already have a low dose of hepatitis B surface antibodies in their bodies, these people can be injected with 60ug, usually in one injection.
Especially for this kind of people who have hepatitis B patients in their families, they should regularly review the hepatitis B two-half test, and if the hepatitis B antibody decreases, they should go to get the hepatitis B vaccine in time.
