Introduction
If one partner in a couple has not been vaccinated against hepatitis B, their immunity to the hepatitis B virus is low, and the risk of infection significantly increases upon exposure to the virus. When both partners have completed the full course of hepatitis B vaccination and have developed sufficient antibodies, even if one partner is a hepatitis B virus carrier, the other is unlikely to become infected.
It is generally believed that transmission of hepatitis B virus (HBV) between spouses is possible. However, the risk of infection can be significantly reduced if both partners take proper protective measures and receive vaccination. Seek medical attention promptly if any abnormalities occur. The detailed analysis is as follows:
If one spouse has hepatitis B and unprotected sexual intercourse occurs—without using condoms or avoiding sharing personal items that may come into contact with blood—the other spouse may become infected. Similarly, if one partner is a hepatitis B patient and the other lacks hepatitis B antibodies and has not been vaccinated, infection may still occur.
When both partners have completed the full course of hepatitis B vaccination and have developed sufficient antibody levels, the uninfected partner is unlikely to contract the virus even if the other is a hepatitis B carrier. Additionally, practicing safe sex and avoiding sharing personal items can effectively reduce the risk of transmission.
In daily life, it is recommended that both partners receive the hepatitis B vaccine as soon as possible and consistently practice safe sexual behaviors to minimize the risk of HBV infection.
