So GP’s have been told to prepare to roll out the vaccine from November.... IMO that is prudent contingency planning, so that IF the trials show it is effective, they are ready to go with the stock which is already being manufactured.
Flip side of that is if the trials show it’s not effective, they will pour the stocks down the drain and not implement the rollout.
Now, I’m an optimist on it working, but even so “Back to Normal by Christmas” is unrealistic given the time it will take to administer to everyone. Next Easter, maybe.
However, the fundamental point of the article that most people fail to make any preparation for the disaster lasting longer than they expect, is true. It could be 5 years. But I think it’s likely to be sooner than that.
