It is equivalent to accidentally taking a shot of hepatitis B natural vaccine. It's not contagious yet. If the liver function and B-ultrasound are normal, there is no need for treatment. This kind of specific immunity to hepatitis B virus obtained through natural immunity is better than artificial inoculation of hepatitis B vaccine, which is almost lifelong immunity, and there is no need to vaccinate hepatitis B vaccine in the future.
