If this is the same Dr. Hilary Koprowski that conducted vaccine experimentation in the Belgian Congo in the 1950's and used but denies because of pride and arrogance his use of chimpanzee organs in the creation of the above descried vaccine then may he repent and admit his mistake. I hope you do so to find forgiving higher being. Otherwise your hypocrasy and denial of documented fact which links the spread of the siv virus in chimpanzees to humans as hiv is a unforgivable tarnish on an otherwise brilliant mans career and life. You know what you did Dr. and it is time you conceed this to the world and to god. in doing so you will recieve his and our forgiveness. If this is not said Dr. Koprowski I appologise and ask you and my god for forgivness. I am fairly certain with my research that you are the man. Correct me if I am wrong please. If I am right don't try to convince me that you are not at fault in this scourge of humankind. Just please repent. You know I am right.
