Vaccination itself is not sufficient. One must also be a responder to the vaccination, that is, after vaccination, he must show a level of HBsAb > 10miu/ml.
Okay.
How about my husband is safe from HBV, he didnt contacted from me, because he was vaccinated?
The test for Hepatitis infection is not hbvdna, it is whether HBsAg is positive or negative. To get a good picture, the complete serology test such as HBsAg, HBsAb, HBeAg, HBeAb, and HBcAb should be carried out.
Many chronic Hepatitis B patients have hbvdna < 20 iu/ml.
