News of the vaccine are somewhat premature.
It's about half way through the testing needed, although results look very promising.
Then, because it's an RNA vaccine, the logistics for distribution will be a bit daunting, as it will need a -75 oC cold chain. There aren't many of those freezers around. They are usually -20 oC.
At research labs we may have 1 of those for 3 or, often, way more -20 oC.
