Patient's question:
The baby's third dose of the hepatitis B vaccine is uncertain whether it was given. The baby is now 8.5 months old, and a blood test showed negative for hepatitis B surface antigen and positive for surface antibody. What should I do? Should I still get another shot?Doctor's answer:
The time it takes to develop antibodies after receiving the hepatitis B vaccine varies from person to person. You have already developed antibodies in your body, so you no longer need to get vaccinated.
