B.o.B on Bayer dumping AIDs contaminated medication overseas

Im not sure if anyone heard of or remembers when Bayer discovered that one of their hemophilia medications (injection) was contaminated with the AIDs virus. Bayer then knowingly pulled the contaminated drugs off shelves in the U.S and dumped them overseas is other countries. This was definitely a major contributor to the epidemic in the 80's. B.o.B discuseses this in the following music video.
