We can't tackle the pandemic without figuring out which Covid-19 vaccines work the best
There may be several Covid-19 vaccines by winter, but there will also need to be a study comparing the viruses to one another as part of rolling out widespread vaccination.
Running a study comparing the vaccines to one another would ensure the most lives are save while hurting the fewest and spending the least.

With at least 40 vaccines being tested, the ways by which they prepare the immune system to stop the coronavirus are more disparate than we have ever seen. Though it's hard to predict how well each vaccine will work, it's easy to anticipate that they will not work equally well nor have the same side-effect profiles.
