Explained: Why a coronavirus vaccine is more than a year away

Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases and member of the Coronavirus Task Force created by President Trump, explains why a viable vaccine, if created, would take a year to a year and a half, no matter how fast you go.
“A vaccine that you make and start testing in a year is not a vaccine that’s deployable,” he said.
