Hepatitis B: Risks and Vaccination Guidance - Gastroenterology and Hepatology

Hepatitis issues

Dear Doctor:
1.
I would like to ask about my test results from the medical laboratory for Hepatitis B.
The results show Hepatitis B Antigen: 0.01 (-) and Hepatitis B Antibody: 22.13 (+).
If my partner is a carrier of Hepatitis B, is there a possibility that I could be infected? Should I receive the Hepatitis B vaccine?

WW, 30~39 year old female. Ask Date: 2017/03/06

Dr. Chen Shidian reply Gastroenterology and Hepatology

Hello, sir.
You should not need to receive another dose of the vaccine.
If there is a genuine risk of exposure, you may receive one dose, and then have a blood test done one month later.
Changhua Hospital cares about your health.

More Info

Dear Patient,
Thank you for your inquiry regarding Hepatitis B and your concerns about potential infection and vaccination. Based on the results you provided, it appears that you have a negative Hepatitis B surface antigen (HBsAg) test, which indicates that you are not currently infected with the virus. Additionally, your positive Hepatitis B surface antibody (anti-HBs) level suggests that you have immunity against Hepatitis B, likely due to previous vaccination or past infection that has resolved.

1. Risk of Infection: Since you have a positive anti-HBs result, you have a protective immunity against Hepatitis B. This means that even if your partner is a carrier of the virus (HBsAg positive), your risk of contracting the virus is significantly reduced. However, it is important to note that while the presence of anti-HBs indicates immunity, it does not guarantee absolute protection in every situation. Therefore, it is advisable to maintain safe practices, especially in intimate relationships, to minimize any potential risk.

2. Vaccination Guidance: Given your current antibody status, there is generally no need for you to receive the Hepatitis B vaccine again. The presence of anti-HBs indicates that you have sufficient immunity. However, if there is any uncertainty regarding your immunity status or if you have concerns about your partner's viral load or health status, it may be beneficial to consult with a healthcare provider. They can assess your specific situation and determine if any additional vaccinations or booster doses are necessary.

3. Monitoring and Follow-Up: It is wise to have regular check-ups, especially if your partner is a Hepatitis B carrier. Regular monitoring can help ensure that you remain healthy and that any potential issues are addressed promptly. If you experience any symptoms suggestive of Hepatitis B infection, such as fatigue, jaundice, or abdominal pain, you should seek medical attention immediately.

4. Understanding Hepatitis B Transmission: Hepatitis B is primarily transmitted through contact with infected bodily fluids, including blood, semen, and vaginal secretions. It is not transmitted through casual contact, such as sharing meals or utensils. Therefore, while your partner is a carrier, practicing safe sex and avoiding sharing personal items that may come into contact with blood (like razors) can help reduce the risk of transmission.

5. Conclusion: In summary, your current test results indicate that you are not at risk of Hepatitis B infection due to your immunity. You do not need to receive the vaccine again unless advised by a healthcare professional. Continue to monitor your health and maintain open communication with your partner about their Hepatitis B status. If you have any further questions or concerns, do not hesitate to reach out to your healthcare provider for personalized advice.

Stay healthy and take care!
Best regards.
