only when you are hbsag positive it makes no sense to have vaccine, it will make no harm anyway but once hbsag positive it is a waste of money
have hbv vaccine plus immune globulins, in most countries you get it at pharmacy and test hbsab in 1 month, once hbsab>10miu/ml you are immune to hbv
as to testing again it is useless to test hbsag before 6months, if you get hbv you clear hbsag in 6-1 months and no drugs will be given to you whatsoever anyway because hbv is cleared by immune system, it is only babies at birth that get chronic hbv because they have no immune system
and sorry one last question,how can i know my status if i can't get tested?
and can i get vaccine now which i don't know my status?
I was asked by my doctor for this test and its recommended to be tested for hbv if you had sex intercourse, so you say no one gets hbv? or what exactly?
it is useless to test for hbv this way, all adults clear it by immune system and can have vaccine, so nobody tests the way you do
