Genetic Engineering Could Make a COVID-19 Vaccine in Months Rather Than Years

By early April almost 80 companies and institutes in 19 countries were working on vaccines, most gene-based instead of using traditional approaches, such as those that have been employed in influenza vaccines for more than 70 years. The labs predicted that a commercial vaccine could be available for emergency or compassionate use by early 2021—incredibly fast, given that vaccines to brand-new pathogens have taken a decade to be perfected and deployed. Even the Ebola vaccine, which was fast-tracked, took five years to reach widespread trials.Scientific American
