The Doctor's World column on AIDS origins makes valid points in the argument that Edward Hooper's theory of vaccine contamination should be explored further. Those scientists who feel the legitimization of Hooper's theory would tarnish public confidence in the safety of vaccines are not only shortsighted, but naïve.

Anyone who has followed the AIDS epidemic has pondered either in public or private numerous rumors and theories, from tainted vaccines to government conspiracies. With no cure in sight, more research into the origins of this epidemic not only has the potential to win tangible scientific results but also the trust of millions who often feel they are only receiving information that has been deemed palatable to the public.
