In contradiction to statements made by the Trump Administration, CDC director Dr. Robert Redfield testified in front of Congress that masks are a more effective protection against Coronavirus than a vaccine. He went on to give the summer of 2021 as the best guess for when there would be widespread distribution of a Coronavirus vaccination. The President said Dr. Redfield was confused and that the vaccine will be ready next March and that of course vaccines are better than masks. Who do you think has the straight story?
