Scientists in the United States say they have made a breakthrough in the search for a vaccine for SARS.The disease caught the world unawares last year and killed 800 people.The scientists have managed to find a way to stop the virus invading human cells in the test tube using a synthetic human antibody, a man made version of a protein that plays a key role in the body’s immune response. The antibody binds to the SARS virus, stopping it from entering and infecting human cells. The researchers say it shows promise as an emergency treatment for SARS. They hope to carry out clinical trials in collaboration with scientists in China.(Source: ABC Health News, Feb 2004)
