Lots of "how to speed up the vaccine" posts - whilst understandable probably not really the biggest issue right now.
We *cannot* vaccinate ourselves out of the hole that has been dug.
Cases are doubling at least every fortnight and are currently close to half a million a week. Actual infections will be at least double that (we don't catch anywhere near all with testing) That will continue to grow exponentially unless we take action. So we are currently infecting more people than are being vaccinated, and the number infected will be more than we can feasibly vaccinate until the virus has run through the entire population. That's something like half a million dead. Maybe half that if vaccination is done at the fastest possible rate.
Our hospitals will be overwhelmed - the average age in ICU is just 60.
We need to lock down *now* to give vaccination any chance. A really hard shut down through January gives us a fighting chance, despite the delay and dither so far. Dependent on how well that works we may need to extend for another month, or even two.
We should have done three weeks ago when it became apparent cases were out of control in London and the new variant was the likely cause.
And, of course, manufacture and logistics are very, very unlikely to go smoothly to plan for such an unprecedented operation.
