Can you please supply a data based on individual researcher and not supplied by a drug company which makes the vaccine. In my surgical practice were nearly all patients get tested for hepatitis B,i have found the incidence very low.i feel that people who are not health workers(Doctors ,nurses,and others)and are not exposed to serum or blood either sexually or through other hospital treatment,stand a very low risk of getting exposed. I feel the low risk population does not require the vaccine. Will need views of the readers especially doctors.... Dr.A.V.Pathak
