I had the HBV vaccination also, but did not have the antibodies. I have been re-vaccinated, but don't yet know if it took this time.
Hello!
The reason for getting a hepatitis B shot at birth is so the baby makes blood protections against it...Sometimes vaccinations (shots) don't work and the child can get sick anyway...The only way to know is to get a blood test to show if if the blood has grown the protections...Just so you know, Hepatitis B is only spread by sexual contact...
