Patient's question:
The son received the hepatitis B vaccine at birth and then had 2 more shots later. I don't remember the exact time interval, but it was around half a year with 3 shots in total. I had a small notebook to record it, but I lost it. Now the child just turned one year old. Do we still need to get him vaccinated? I remember the vaccine I received can last for several years.Doctor's answer:
Born, I received the hepatitis B vaccine, and later got 2 more shots. I don't remember how long it was exactly, but it was around half a year to get 3 shots. The child just turned one year old. Consultation needed: After following the prescribed procedure to receive 3 doses of hepatitis B vaccine, 51% of recipients still have antibodies against the hepatitis B virus, and they still have resistance to the hepatitis B virus. It is confirmed that for the population vaccinated with hepatitis B vaccine, the immunity of half the people can last at least 15 years.
