Question
Hello doctor,
My sister is currently infected with chronic active viral hepatitis B. This morning I found out that my sister has been using the wrong toothbrush for 2 days now, but she has gingivitis, so she has scratches. I have had an antibody test before, which is a safe indicator, but I am still afraid of getting infected. The doctor asked me if I have been vaccinated against hepatitis B, is there a high risk of infection? I thank you doctor.

Hello,
With the question "If I have been vaccinated against hepatitis B, is the risk of infection high?" , the doctor would like to answer as follows:
According to you, if you have been vaccinated against hepatitis B and already have enough antibodies to protect your body against hepatitis B virus, specifically the amount of HBsAb antibody > 10 IU/L, you will not be at risk of hepatitis B infection.
If you still have questions about hepatitis B, you can go to a hospital under Vinmec Health System for further testing and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
