White House coronavirus advisor Dr. Anthony Fauci said Friday that the chances of scientists creating a highly effective vaccine — one that provides 98% or more guaranteed protection — for the virus are slim.
Scientists are hoping for a coronavirus vaccine that is at least 75% effective, but 50% or 60% effective would be acceptable too, Fauci, director of the National Institute of Allergy and Infectious Diseases, said during a Q&A with the Brown University School of Public Health. “The chances of it being 98% effective is not great, which means you must never abandon the public health approach.”
