Pfizer requests FDA approval to ease vaccine storage requirements

02:31

Emergency medical physician Dr. Uché Blackstock says, if approved, this will “enable delivery to rural sites, even urban areas that are underreported” in the U.S., and could also be a “game changer” for the rest of the world.
