Researchers close in on SARS vaccine

Emergency Management Alert, June 21, 2005

Genetically-engineered tomato and nicotine plants may be the key to a SARS vaccine, Reuters reports.

Researchers found that the manipulated plants triggered anti-SARS antibodies in mice after being ingested.

After discovering that an S protein on the virus' outer membrane was the best antigen for a vaccine, scientists found a way for the plants to express that S protein.

SARS, which was first discovered in China in 2002, is responsible for 774 deaths and 8,000 other illnesses, though no outbreaks have occurred in recent months.
