also hbv can take even 6 months to start an infection (nothing happens before) so dont waste time by checking hbsag, it is useless, you just have to take vaccine since you have as little as a couple of weeks to 6 months for the infection to start and virus to show up in the blood
hbv must not be detected, useless, you must take immune globulins and hbv vaccine and not worry about hbv.in any case even if you get it hbv is cleared more than 95% cases as adults, it gets cronic only at birth or very young
as to hiv it is all another story, no vaccine available so you just have to check and hope you didnt get it
you forgot hcv which has no vaccine too and gets cronic on more than 80% according to genotypes
