JERUSALEM (Reuters) - A scientist who helped to discover the HIV virus said he has made progress toward producing an AIDS vaccine and hopes to launch a clinical trial in about a year.
Dr. Robert Gallo, the director of the University of Maryland's Institute for Human Virology, said results from animal studies were encouraging.
Scientists believe a vaccine is the best hope for ending the global AIDS pandemic that has killed about 3.1 million people this year. But defeating the virus has proved more difficult than researchers had expected.
Researchers believe an effective AIDS vaccine is still many years away.
