Let's ignore political rhetoric for a day.
I really think that it's a good thing. As it turns out, the previous administration didn't have a concrete plan for distributing the vaccines; they left it to individual states to figure out what to do. The results- many states have tens of thousands of vials at risk of getting destroyed, while other states are running short.
Amazon has the technological and physical infrastructure capacity to facilitate the distribution of vaccines. The previous leader didn't quite believe in science/vaccines, and on several times he stated that the virus would just "go away". Well, it didn't, and over 400k are dead. I think that it's time we changed gears, set politics aside, and tackle this monster head-on.
There are obvious reasons why Amazon didn't offer to work with the previous administration. It's a new day, let's get it done!
