Washington - A vaginal gel which can kill the HIV virus during sexual intercourse was hailed Monday for showing it was somewhat effective in preventing infection and for holding promise as another weapon in the arsenal against the deadly disease.
The gel, PRO2000 produced by Indevus Pharmaceuticals, was 30 per cent effective in reducing the incidence of AIDS during four years of trials in Africa and the United States, according to research revealed at an AIDS conference in Montreal, Canada.
