the antibody hbsab developped by vaccine is low, to protect from hbv infection it must be higher than 10miu/ml
he never had an infection with hbv because antibody hbcab is negative
since this virus is very easy to get and like herpes virus is only controlled by immune system but rarely complitely eradicated it is better to have a vaccine boost shot so that the antibody gets higher than 10, a good vlue is 250-500miu/ml
not to menthion that there is no drug for hbv eradication if infection gets cronic
