if both igm or igg get positive vaccine doesn t work anymore because the illness has started already or cleeared already
you should have checked both since it is easy you have had hav already and in some sian countries it is endemic
in any case check them both and make vaccine

Thanks for you reply
I do understand not necessary to take vaccine if have already infected by Hep A. What I need to know is the IGg Anti HAV for virus A needed under my condition because my Hep A Igm ( Anti-HAV IgM)- negative .If my Igg-anti hep virus A comes positive then no need of vaccine. am I right?
should I take IGG test for hepatitis A?
just take vaccine it makes no difference if you had hav already in this case vaccine just makes a rise in the antibody titer
the only difference is the money you spend for vaccine that could be saved but you also spend money for igg hav test
