A vaccine against HBV (Hepatitis B virus) can’t make you HBVag negative. Vaccines serve to prevent infection not to cure someone who is already infected. If he was infected with HBV in the past there are 3 possibilities:
1. To become a carrier (2%);
2. To overcome the infection and become immune to further infections with HBV (90%);
3. To become chronically infected with HBV (8%).
Only in the second case can a person who was “positive” to HBV become “negative” after overcoming the infection.
Carriers, acute and chronically ill people can transmit the HBV to other people.
