Data from two leading COVID-19 vaccine trials indicate they may be between 90 and 95% effective. Dr. Moncef Slaoui, the chief scientist in charge of the U.S. government's vaccine development program, Operation Warp Speed, tells NPR he's optimistic there is "a light at the end of the tunnel."
Dr. Anthony Fauci told NPR the results are worth celebrating — but that they should not be seen as a signal to pull back on public health measures. He also said the first vaccine doses may be available next month.
But it will still be months longer before any vaccine is widely available. Two former government health officials — Scott Gottlieb and Andy Slavitt — tell NPR that in the meantime, the pandemic is could kill 200,000 more Americans.
