Revaccination for Hep B

06/22/2011

Question:

if someone had a Hep B vaccination over 10 years ago and their new employer wants them to prove that they did however it is not possible for them to show proof, would it harm the person to have a new series of Hep b vaccination?

 

 

Answer:

No, it would not be harmful to take a second series of hepatitis B vaccines unless you have a life-threatening allergy to baker?s yeast, or to any other component of the vaccine, or if you had a life-threatening allergic reaction to a previous dose of hepatitis B vaccine, then you should not get another dose.

Also, anyone who is moderately or severely ill when a dose of vaccine is scheduled should probably wait until they recover before getting the vaccine. If you cannot find documentation of your hepatitis B vaccine series 10+ years ago, consider asking your new employer to check your blood for presence of hepatitis B surface antibodies (HBsAb).
