During the late 1970’s and early 1980’s, factor products were manufactured using donations of human blood. These donations contained the HIV virus which causes AIDS. As a result, approximately 60% of hemophiliacs who were treated contracted the HIV virus.
The death of thousands of people with hemophilia drove the medical and scientific community to find to create safe factor products. Today, only a few products contain elements of donated blood but these products include safety steps in the manufacturing process such as heat treatment and filtration to guard against any virus ending up in the finished product. The good news is that most of the products are now manufactured synthetically.
Though these products are safer to use than they have ever been before, people who infuse any medication into their veins take a certain risk.
