If you are positive for hepatitis B 4 or 5, you can temporarily skip the hepatitis B vaccine and wait for the emergence of hepatitis B surface antibodies for dynamic observation. Because hepatitis B 4 and 5 positive indicates hepatitis B core antibody and hepatitis B E antibody positive, where hepatitis B core antibody is the marker of ever infected with the virus, indicating ever infected with hepatitis B virus. Hepatitis B E antibody is a marker of declining viral replication. When 4 and 5 are positive at the same time, it mostly indicates that the hepatitis B virus is currently in the recovery period after clearance. This condition may produce surface antibodies by itself, but it may be in the window period at present, and surface antibodies may appear later as time lengthens. Therefore, you can temporarily skip the hepatitis B vaccine and wait for the hepatitis B surface antibodies to appear on their own. At this time, you can first observe dynamically and check the hepatitis B surface antibody regularly.
