Even further behind in development, but still promising, are two new antibodies identified by a group of researchers working at a number of labs that, at least in a dish, seem to neutralize the virus and thwart attempts...
Without an answer, developing vaccines is a very halting process. "The virus is a moving target," says Dr. Gary Nabel, director of the Vaccine Research Center at the National Institutes of Health (NIH). "It is constantly changing its genetic makeup through mutations.
