Recent studies suggest that the smallpox vaccine provides some level of defense against HIV. Both the smallpox vaccine and HIV exploit a receptor called CCR5, which is expressed on the surface of white blood cells. Researchers theorize that one factor in the sudden spread of HIV in the early 1980s was the result of eradication of smallpox in the late 1970s, and the subsequent and abrupt decline in smallpox vaccinations worldwide.

Famous quotes containing the word protection:
“... actresses require protection in their art from blind abuse, from savage criticism. Their work is their religion, if they are seeking the best in their art, and to abuse that faith is to rob them, to dishonor them.”
—Nance O’Neil (1874–1965)
