Pfizer's COVID-19 vaccine becomes first to win FDA's full approval, paving way for boosters, mandates Eight months after first authorizing the Pfizer-BioNTech COVID-19 vaccine for emergency use in the United States, the Food and Drug Administration has issued its full stamp of approval. The FDA's decision to fully license Pfizer-BioNTech's COVID-19 vaccine is expected to trigger more vaccination mandates and allow company marketing of the shot. And it may launch a race for booster shots, allowing doctors to prescribe extra Pfizer-BioNTech shots "off label" to anyone they think should get one. The license only applies to those 16 and over, but the vaccine will continue to be allowed for those 12 to 15 under the previous authorization. #pfizer #pfizervacine #covidvacccine #covid19 @pfizerinc
