In February, a topical microbicide gel was found to cut the odds of HIV infection in at-risk African women by 30 percent, while in September researchers at the International AIDS Vaccine Initiative said they'd discovered two immune-system antibodies that might become powerful, broad-spectrum targets for vaccine research in the future.
