Why didn't approve the same vaccine that is out right now???? What changes were made? Am I reading this wrong??
Pfizer-BioNTech COVID-19 Vaccine contains a nucleoside-modified messenger RNA(modRNA) encoding the viral spike (S) glycoprotein of SARS-CoV-2 formulated in lipid particles. COMIRNATY (COVID-19 Vaccine, mRNA) is the same formulation as the PfizerBioNTech COVID-19 Vaccine and can be used interchangeably with the Pfizer-BioNTech COVID-19 Vaccine to provide the COVID-19 vaccination series.8
