  I thought everyone was saying full approval of vaccines take years of clinical trials. This was done much more quickly than that.

    Most of those years are not clinical trials they are getting funding to run a trail.

    There are years of clinical trials for mRNA vaccines, as well as a countless studies done on SARS-COV viruses. This is just taking some existing technologies and knowledge of the vaccines and creating a new variant of what's been tested before. Also, we know have well over a year's worth of data on millions of people to look at as well.
