Should I Get the Hepatitis B Vaccine After 20 Years as a Carrier?

Hepatitis B carrier

I have been a carrier of hepatitis B for over 20 years.
Since I was a university student, I have been unable to donate blood (the blood donation center informed me that I am a hepatitis B carrier).
In the past decade, my cases have mostly been monitored at China Medical University.
However, in July 2009, I tested negative for HBsAg at Chung Shan Medical University, and in August, I went for a health check at Harvard, where the viral load was 0.5, HBsAg was also negative, and surface antibodies were negative.
Should I receive the hepatitis B vaccine? I have not undergone treatment with interferon or antiviral therapy.
Please advise, thank you.

Hello Mr.
Wang,
It is likely a case of low concentration HBsAg, which has resulted in a false negative for HBsAg.
You just need to be monitored.

More Info

When considering whether to receive the Hepatitis B vaccine after being a carrier for over 20 years, it's essential to understand several key aspects of Hepatitis B, vaccination, and the implications of your current health status.

Firstly, being a Hepatitis B carrier means that the virus is present in your body, and you may have a chronic infection. The presence of HBsAg (Hepatitis B surface antigen) indicates active infection, while the absence of HBsAg and the presence of anti-HBs (antibodies against Hepatitis B) typically suggest recovery from infection or successful vaccination. In your case, you mentioned that your recent tests showed HBsAg negative and anti-HBs negative, which raises some important considerations.

1. Understanding Your Current Status: If your HBsAg is negative, it suggests that you may not have an active infection at this moment. However, the negative anti-HBs indicates that you do not have protective antibodies against Hepatitis B. This situation can occur if you have cleared the virus but did not develop immunity, or if you are still a carrier without active viral replication.

2. Vaccination Considerations: The Hepatitis B vaccine is designed to stimulate your immune system to produce antibodies against the virus. Given that you currently lack these antibodies, receiving the vaccine could be beneficial. However, it is crucial to consult with a healthcare provider who can assess your specific situation, including your liver function and any potential risks associated with vaccination in the context of your Hepatitis B status.

3. Potential for Immune Response: In some cases, individuals who are carriers may still respond to the vaccine, but the response can be variable. Studies have shown that a small percentage of individuals (approximately 10%) may not develop antibodies even after vaccination. Therefore, monitoring your response to the vaccine through follow-up blood tests will be essential.

4. Monitoring and Treatment: Since you have been a carrier for over 20 years, regular monitoring of your liver function and viral load is crucial. This includes periodic blood tests to check for liver enzymes, HBsAg, and HBV DNA levels. If you have not undergone treatment such as interferon or antiviral therapy, discussing these options with a hepatologist may also be beneficial, especially if there are signs of liver damage or if you are at risk for complications.

5. Lifestyle and Health Maintenance: In addition to vaccination and monitoring, maintaining a healthy lifestyle is vital for liver health. This includes avoiding alcohol, maintaining a balanced diet, exercising regularly, and managing any other health conditions you may have.

In conclusion, while it may be advisable for you to receive the Hepatitis B vaccine given your current lack of protective antibodies, it is imperative to consult with a healthcare professional who specializes in liver diseases. They can provide personalized recommendations based on your medical history, current health status, and the results of your recent tests. Regular follow-up and monitoring will be essential to ensure your health and to manage any potential risks associated with being a Hepatitis B carrier.
