U.S. gives full approval to Pfizer’s COVID-19 vaccine; what does this mean?

Moderna has also applied for full approval, and Johnson & Johnson has said it hopes to apply later in the year

The united States has given on Monday. It means Pfizer’s shot for people 16 years  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 authorisation, 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.
