How the COVID-19 vaccines were created so quickly - Kaitlyn Sadtler and Elizabeth Wayne

Discover how mRNA vaccines help your immune system fight viral infections and how this decades-old technology was used to create COVID-19 vaccines. -- In the 20th century, most vaccines took over a decade to research, test, and produce. But the vaccines for COVID-19 were cleared for emergency use in less than 11 months. The secret behind this speed is a medical technology that’s been developing for decades: the mRNA vaccine. So how do these revolutionary vaccines work? Kaitlyn Sadtler and Elizabeth Wayne dig into the science of mRNA technology.
