What does full approval of Pfizer’s COVID-19 vaccine mean? It means Pfizer’s shot for people 16 and older has now undergone the same rigorous testing and regulatory review as dozens of other long-established vaccines. COVID-19 vaccines in the U.S. were initially rolled out under the Food and Drug Administration's emergency use authorization, which allows the agency to speed the availability of medical products during public health emergencies. Under the process, the FDA waived some of its normal data requirements and procedures to make the COVID-19 vaccines available months earlier than would have been possible under normal circumstances.
