TED-Ed: How the COVID-19 vaccines were created so quickly | Kaitlyn Sadtler and Elizabeth Wayne

The video explains the rapid development of COVID-19 vaccines using mRNA technology, which leverages the body's cellular machinery to produce viral proteins and trigger an immune response. Unlike traditional vaccines, mRNA vaccines do not contain live viruses and can be quickly adapted to new diseases. The video details the mechanism of mRNA vaccines, their safety, and their advantages, including the potential for rapid development of new vaccines.
