"SARS killed nearly 800 people when it emerged from China in 2002 and spread around the world in the first half of 2003. Only a handful of isolated outbreaks have been spotted since that initial epidemic.
Aware that the disease could re-emerge, several groups have been trying to make a vaccine against the virus. They are mainly trying to find ways to expose people to a protein on the virus's coat, called the spike protein, which helps it to enter cells. This should jolt the immune system into recognizing the virus during a future infection and making antibodies that attack it.
In the new study, Gary Nabel of the National Institute of Allergy and Infectious Diseases in Bethesda, Maryland, and his co-workers injected mice with spike protein from a SARS virus taken from a human patient infected in early 2003. They then collected the antibodies the animals produced.
In lab experiments, they showed that these antibodies were unable to attack spike protein from a different strain of SARS, isolated from a patient infected in late 2003.
The team next tested whether the antibodies would attack spike proteins from two SARS strains isolated from civets, from which the virus is thought to have originally jumped into humans. In this case, they found hints that the antibodies actually boosted the ability of the virus to infect cells. The study is published in the Proceedings of the National Academy of Science1.

Caution raised over SARS vaccine - Nature
Jab against one strain might worsen infection with others.
