The prospect of a COVID-19 vaccine before the end of 2020 seemed preposterous just a few months ago. Yet, here we are, getting ready to roll up our sleeves.
What are we to make of this “rushed” vaccine? Could it really be as safe as those that take years to develop?

COVID-19 vaccines are required to clear all the same hurdles as past vaccines in order to gain regulatory approval. Their compressed timelines do not reflect less rigorous testing; they reflect the fact that COVID-19 vaccine development was an “all hands on deck” global priority.
To better understand why COVID-19 developers smashed the world record, let’s see what it takes to develop a vaccine, and how these steps were safely accelerated.
How are vaccines normally developed?
Vaccine development always begins with a grueling search for the single best potential vaccine to test in humans. This pre-clinical (lab-based) stage often…
