The professional they were asking questions of was careful to correct them by saying it's "warmer" rather than just snapping that it's actually "higher" temperature - because this way sidesteps the confusion, but it'd be easier to just not have that problem at all.
I believe this can happen in the US, but hardly in any place where people are used to Celsius.
I have experienced -30C in Germany and Norway, and -40C in Russia. Even in the mountain in Spain you can get -20C. People have -18C in the freezer.
It is obvious for people what 0C is: water freezes, and that is something that everybody experiences today just using a refrigerator.
But most people are not used to what K means. Only for scientists and maybe engineers is obvious, but you need a lot of things to know before it is easy to understand.
So they started vaccinating people without delaying it 3 months because it was an emergency. But after 3 months of testing we will be able to know how temperature storage affects the vaccine.
Johnson and Johnson doesn’t add easier temps to the mix. It adds the fact that it’s a single dose vaccine to the environment.
If you did think it was competitive pressure that was driving it then you should be suspicious about the Israeli studies that show that a single dose of thrnPfizer vaccine is 85% effective upto 4 months later.
Even the surplus AZ doses are just sitting in storage, official centers don't use them if you are not eligible yet. Even if that means less people are getting shots. As soon as doctors are jumping in, that will change. We also have, quite likely, an incredible amount or surplus doses come Q2, early Q3.
