Hi,
In covid vaccine some say to take a booster vaccine. If someone was vaccinated 30years ago for example for hepb, do they need to take again as booster vaccine shot ?
Br,
Hi @hepb1,
That will be the case for a small sample of people. For the majority, that won’t be necessary since they remain to have strong antibodies against HBV. I hope this answers your question. Bansah1.
@hepb1, I’d agree with @Bansah1 here. For someone at increased risk of exposure, it may be worth them testing their antibody titers to see if they are still at protective levels.

What blood test should be done exactly ? What to measure ?
The test is called hepatitis B titer test. and it will be your HBV Antibody. Anything 10 Iu/ml or higher is considered as a strong protection. Best, Bansah1
Specifically, you would want to test for anti-HBs antibody titres: if this is about 10mIU/mL it is considered protective and they should not worry about being vulnerable to HBV infection
