China's outbreak may not peak for months
Cases of novel H1N1 may not peak in China for several months, its health ministry said today, according to the Associated Press (AP).

The country has confirmed more than 100,000 cases but only 326 deaths. China's peak flu season, which could last till March, will be critical for flu control and prevention, a spokesperson said.
NIAID to test vaccine in HIV-positive volunteers
The National Institute of Allergy and Infectious Diseases (NIAID) is recruiting HIV-positive volunteers to test whether they need a larger-than-standard dose of H1N1 vaccine. People who have suppressed immunity are among the priority groups for H1N1 vaccination because of their risk of flu complications, but their HIV infection may dampen their response to the vaccine, the NIAID said yesterday. The trial volunteers will receive two doses of either 15 or 30 micrograms of antigen.
