Here's the thing.
It took the authorities just a few weeks to get a whole load of emergency hospitals up and running from scratch.
It is going to take a year or so to get a vaccine to the point of mass production.
The vaccine will be developed at university research facilities using public money but will be manufactured by American big pharma who will nab most of it for the USA and charge the rest of us, including third world countries, big bucks to buy it from them.
So, if we can get hospitals running in just days why don't we spend the year we are waiting for the vaccine to be tested, building public facilities throughout the world ready to manufacture the vaccine and then give it to the world at cost or for free even.
For the record, volunteers who were given an Oxford University developed proto-vaccine have developed antibodies that will protect them from catching COVID-19.
