The Pfizer-BioNTech COVID-19 Vaccine, also known as BNT162b2 or Comirnaty, is an mRNA-based vaccine developed collaboratively by Pfizer Inc. and BioNTech SE. It was designed to provide immunity against the SARS-CoV-2 virus, which causes COVID-19. The vaccine works by delivering messenger RNA (mRNA) into cells to instruct them to produce a harmless piece of the virus (the spike protein), thereby stimulating the immune system to recognize and fight the actual virus.
