Patient's question:
After a child is born, they receive the hepatitis B vaccine. Now they are about to start kindergarten, and during the check-up, it was said that no antibodies were found. They need to be revaccinated. I don't know if it's necessary.Doctor's answer:
Nowadays, children are routinely vaccinated against hepatitis B. Some can produce antibodies, while others cannot. If antibodies are not produced, a booster hepatitis B vaccine is needed.Guidelines:
Developing antibodies after vaccination against hepatitis B means immunity to the virus, and it is generally unlikely to contract hepatitis B. Vaccination should be administered for the child's health, not just to enroll in kindergarten.
