Smallpox Vaccine Could Prevent AIDS
An anonymous reader writes "Researchers at George Mason University have published a preliminary report which suggests that the Smallpox vaccine might be able to slow the spread of AIDS. Various news stories have suggested that it may be due to the vaccine interacting with the CCR5 receptor, which is a cellular infection route in another related poxvirus, and also commented on the rise of AIDS in the years after smallpox was declared eradicated and the smallpox vaccine was no longer given as a matter of course."
Recently those in the U.S. military were vaccinated against smallpox. It seems easy to track whether they have a lower incidence of AIDS infection.
