A member asked:

Can i inject third dose of hepatitis b vaccine after 1 yr of first dose?

Specializes in Nephrology and Dialysis

Yes, if you missed the third dose at 6 months then it is fine to take at this time, 12 months later. However, due to the delay the effectiveness is not known so you should have the Hep B surface antibody titer checked after 1-2 months and you will know. Good luck.

Our infant did not receive the hepatitis B vaccine at birth - is it okay to give the first dose with all the other vaccines at 2 months? Or is it worth spacing it out? Is there any benefit to spacing vaccines out vs. all at once?
