BEIJING, China (Reuters) -- Chinese researchers have developed a SARS vaccine that has passed the first stage of human trials, state media has reported, raising hopes for the prevention of a virus that killed some 800 people since it emerged in 2002.
Antibodies against Severe Acute Respiratory Syndrome (SARS) developed in 24 of 36 volunteers in the trial, the official Xinhua news agency said Monday, though several more clinical trials were required before the vaccine would be ready for commercial use.
