FDA report indicates Pfizer vaccine is ‘effective and safe,’ doctor says

04:03

Dr. Richard Besser, former acting director of the CDC, tells TODAY that the FDA’s review of the Pfizer coronavirus vaccine “is the report of a vaccine that is extremely effective… and extremely safe.” He says that “they found a significant level of protection, about one week, after the first dose,” but adds, “that doesn’t mean you don’t need a second dose.” But while he calls the news “exciting,” he warns: “This is the most dangerous period of the pandemic.”
