Researchers around the world were working to develop a vaccine for hepatitis B, and doing so required a steady supply of antibodies like Slavin’s, which pharmaceutical companies were willing to pay large sums for. This was convenient, because Slavin needed money. He worked odd jobs waiting tables and doing construction, but he’d eventually have another hemophilia attack and end up unemployed again. So Slavin contacted laboratories and pharmaceutical companies to ask if they wanted to buy his antibodies. They said yes in droves.
