Pfizer-BioNTech, the American-German paired company, has been the leading company for providing a COVID-19 vaccine. The FDA (Food and Drug Administration) granted Emergency Use Authorization in early December of 2020. Pfizer-BioNTech was later given emergency validation by the World Health Organization. As of August 23, 2021, Pfizer-BioNTech is the first vaccine to be FDA approved, meaning they have met the rigorous standards of the FDA. This is a significant milestone for Pfizer-BioNTech. While many have already been vaccinated, there is now additional confidence in the vaccine.
