ATLANTA — Two new studies found that daily pills prevented infection with the AIDS virus in heterosexual men and women in Africa, bringing new hope for someday offering a medical shield against HIV infection.
“This is good news. This is a good day for HIV prevention,” said Dr. Lynn Paxton of the U.S. Centers for Disease Control and Prevention, who has coordinated the agency’s research into HIV prevention.
Earlier this year, another study found the same pills did not prevent the AIDS virus among women in Kenya, Tanzania and South Africa. But researchers now say that study may have been flawed based on the success of the two studies announced Wednesday.
The first of the new studies, run by the CDC, involved more than 1,200 men and women in Botswana. About half got a daily pill, Truvada, an HIV treatment made by Gilead Sciences Inc. The other half got a fake pill.
