HIV remains a major health concern for women and children globally. Worldwide, the majority of new HIV infections occur in young women. Each year, 1.5 million women living with HIV become pregnant.

In an effort to prevent HIV transmission to women and their children, researchers from the University of North Carolina at Chapel Hill demonstrated the effectiveness of a new anti-HIV medication, 4'-Ethynyl-2-fluoro-2'deoxyadenosine or EFdA, in pre-clinical animal models. They found that EFdA can prevent vaginal and oral transmission of HIV. Read full article here.
