COVID-19, Coronavirus Vaccine, Pfizer

Pfizer/BioNTech announced it's starting the application process, seeking full approval from the U.S. Food and Drug Administration (FDA), for its two-dose COVID-19 vaccine.

This marks the first COVID-19 vaccine in the U.S. to be assessed for full approval. Right now, the vaccine is being distributed and administered under "emergency use authorization."

As Pfizer submits data for the full approval application, the FDA will take several months to review it before making a decision.
