Every American adult should have a small scar on his upper arm or thigh: a smallpox vaccination. Smallpox once was a deadly scourge-killing millions. Vaccinations have virtually wiped it out. It's an ingenious concept: You introduce a minuscule amount of weakened or dead disease-causing bugs into the human system. The body responds by producing antibodies-a natural antidote that neutralizes the invading bug. Once you have the antibodies, you're immune. So why is it such devastating news when a person tests positive for HIV antibodies?
