A vaginal ring tested in sheep appears able to release an HIV drug for up to three months, scientists report. An anti-HIV vaginal ring could allow sexually active women to gain some protection against the virus without relying on her partner to use a condom. The research is in the preliminary stages, and because the device -- one of several that are under development -- hasn't been tested in women yet, it is unknown if it will work in people. Experts point out that results from animal research do not always apply to humans.
