Hi Im so scared,could someone please help me i have a quick question.does hep b vaccine protect against precore mutant hep b? I understand it doesn't protect against S protein mutant since it's surface protein, just not sure If that's the only type of mutation it doesn't protect.
My boyfriends E antigen just turned from positive to negative however the DNA is still positive, this should mean he has precore mutation I have antibody just not sure whether he is able to infect me if he has mutated.
Thanks so much
