concern

I've been sexually active with some one with hepatitis b, should i seek medical treatment ( vaccine)or maybe testy to see if I've been infected.

yes you should get hbsag and hbsab test (same day or day after result) and then go to pharmacy and buy vaccine if both negative

if you are not a drug addict your immune system works (drug addicts have less immune system than aids people...) and your chances of a cronic (chronic) hbv infection are less than 3% so as an adult hbv infection is never treated until cronic (chronic) (it is only babies that get it cronic (chronic) at birth)
