I unknowingly expose myself to a hbv+ girl on February 2015.This is my eight months of hbv+. I get weak most time and I slim down. I want to start Tenofovir for six months and vaccine four times within the six months, then every six months I will treat with tenofovir for one month, I'm in Nigeria, the lab center is only two nation wide, very expensive and distant from me. I just need the possible cheap option to avoid liver complication. I cry to God to please help pharmaceutical industry develop the cure. Advice please
