Whether or not you can get the hepatitis B vaccine if you have 100 hepatitis B core antibody should refer to the results of the other items in the hepatitis B penta test.
If the hepatitis B core antibody is 100 and the results of other tests in the hepatitis B five tests are negative, it means that you have been infected with the hepatitis B virus before, but you have not produced the hepatitis B antibody now. In this case, it is necessary to take hepatitis B vaccination to avoid re-infection.
However, if the hepatitis B core antibody is 100 and the hepatitis B surface antibody is positive. It means that you have been infected by Hepatitis B virus in the past and you have produced Hepatitis B antibodies, which can effectively protect you, so you do not need to take Hepatitis B vaccine at this time, and you can also achieve the preventive effect.
Therefore, the need for vaccination should be referred to other test results, and it is recommended to consult a doctor in time for the doctor’s opinion.
