It was the fastest a vaccine had ever been developed.

Vaccine Development:

In 2020 vaccines for Covid-19 shattered previous records, going from development to approval in a matter of months. That speed was driven by billions of dollars, and a global effort.

But in some cases, it was also because of a breakthrough in vaccine technology decades in the making something that could shrink this timeline going forward, and change how we make vaccines altogether. Vaccines teach your immune system how to respond to a threat.
