Six volunteers have received a cocktail of China's experimental AIDS vaccines, signalling a new phase in the country's quest to find an indigenous remedy to fight the deadly disease which is spreading rapidly, the state media reported on Sunday. After receiving medical check-ups, the six volunteers were inoculated with the vaccines in Nanning, capital of south China's Guangxi Zhuang Autonomous Region, on Saturday. The clinical research of the AIDS vaccines will be phased into three parts and the first part will last 14 months. The second part can start only after research result of the first part passes the expert appraisal by the State Food and Drug Supervision Administration. With the first AIDS case reported in 1985, China now has an estimated 840,000 HIV carriers and AIDS patients in each of the Chinese mainland's 31 provinces, autonomous regions and municipalities.
