My husband has HBNS. My child and I have done the vaccine 3 times. Does the vaccine last forever? Or is there an active period? And what if I want more children. Will it be infected?

1 Answer:

A good afternoon. Thank you for asking HealthReplies.com.


Hepatitis B vaccine is a form of prevention of hepatitis virus transmission where the administration of this vaccine will trigger body cells to make immune cells against the virus. These immune cells can be detected from laboratory tests by measuring the antibody titer so that the vaccine is usually given after the previous administration is to measure the antibody titer first if the antibody is still positive and in sufficient levels there is no need to re-vaccinate but if the level is low it should be given a vaccine reset to trigger immunity. We recommend that you check the titer every 5 times.


Transmission of hepatitis B is through body fluids and blood, so there is a greater risk of transmission through the fetus if the mother experiences positive hepatitis B because of fetal and maternal contact very close. In these conditions also can be prevented by giving anti-hepatitis and hepatitis vaccine soon after the baby is born.
