Introduction

If individuals with positive HBsAb have low antibody titers and are not re-exposed to hepatitis B virus or do not receive a booster vaccination, the antibody levels may gradually decline over time and may become negative after several years. This situation is commonly observed when the antibodies naturally wane years after vaccination. However, when antibody levels are high and continuously maintained through immune stimulation, the antibodies may remain positive for a prolonged period without turning negative.

Generally, a positive HBsAb may gradually become negative over time, especially when the antibody level is low. However, if the antibody level is high and the immune system continues to receive stimulation, the HBsAb may remain positive for a prolonged period without turning negative. If concerned, it is recommended to seek medical advice in advance. Detailed explanation is as follows:

If the antibody titer is low and there is no subsequent exposure to hepatitis B virus or booster vaccination, the antibody level may gradually decline over time and may become negative after several years. This situation is commonly seen when antibody levels naturally decrease years after vaccination.

If the antibody titer is high, or if antibodies were produced after a recent hepatitis B infection hepatitis B virus and the immune system remains stable, the antibodies can persist in the body for a long time, even remaining positive for many years, providing continuous protection. This situation is considered a normal immune response.

Individuals with positive HBsAb can periodically check their antibody titers and consult a doctor regarding the need for a booster vaccination if the titer is too low. Practicing good personal hygiene and avoiding direct contact with blood or bodily fluids of hepatitis B patients is recommended. There is no need to be overly anxious about the possibility of the antibody turning negative.
