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


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.”
