"... we are working with great urgency to make our investigational vaccine available to the public as quickly as possible."
This comes as COVID restrictions ease and hospitalizations and new COVID cases decline. However, the concern grows among several top infectious disease doctors.
"I am very worried that we are going to relax too much, this is not the moment to let our guard down," Dr. Ashish Jha said.
