Hepatitus B

[Gregory330]

My son received his Hepatitus B injections (all three of them) in 1999 when he was at school.  He inadvertently forgot he had had them and has just had a Hepatitus B injection today. Will this cause any health problems having had a fourth Hepatitus B injection?  Is there anything he should do or watch out for?  Thank you

If he has a reaction..then I would worry

They usually do boosters with most vaccines...so no need to worry.....look on CDC website and see if boosters are done with that one...he should have gotten his titers checked first.
