While at Caltech, he was involved in researching the genome of
Sindbis virus and the establishment of
flaviviruses as their own family of viruses. The strain of
yellow fever virus he used for this work was eventually used for the development of the
yellow fever vaccine. While exploring Sindbis virus at
Washington University in St. Louis, Rice described how he produced infectious flavivirus
RNA in the laboratory in a 1989 paper published in
The New Biologist. The paper attracted the attention of
Stephen Feinstone who was studying
hepatitis C virus and suggested that Rice use the technique to develop a vaccine for
hepatitis C. In 1997, Rice cultured the first infectious clone of hepatitis C virus for use in studies on chimpanzees in whom the virus was also endemic. In 2005, Rice was also part of a team that showed that a strain of an acute form of the virus identified in a human patient can be forced to replicate in a laboratory setting. Rice's contribution to hepatitis C research has earned him many awards. == Awards ==
