Pfizer COVID 19 Vaccine Explained

Professor Roger Seheult, MD discusses the Pfizer / Biontech COVID-19 mRNA vaccine: How it works and what we know about the safety and efficacy at this time. No mRNA vaccine has ever been approved by the FDA, but Pfizer and BioNTech hope to receive emergency approval based on preliminary data from their ongoing vaccine trial. This two-dose vaccine regimen has limitations including the need for -70 C refrigeration and many questions remain: Will the vaccine prevent transmission and asymptomatic spread? How long will immunity last? Will “90% effective” hold up to peer-review and additional data when it is gathered? (This video was recorded on November 12, 2020).
