COVID-19 Vaccine
About COVID-19 Vaccine
The fastest vaccine development in history, going from virus identification to emergency authorization in under one year. mRNA vaccines from Pfizer and Moderna demonstrated over 90 percent efficacy in clinical trials. The mRNA technology, developed over decades by Katalin Kariko and Drew Weissman, delivers genetic instructions for cells to produce the viral spike protein, triggering immunity. COVID vaccines are estimated to have prevented roughly 14 to 20 million deaths worldwide in their first year. The pandemic accelerated vaccine technology by a decade.
