I prefer that the vaccine be delivered AS Designed.
I fear that people will drop their guard after getting the first/only shot and that things will be even worse.
I dont know that this mixes apples and oranges, but people who take antibiotics, but not finish the course allow the surviving germs to be resistant to the treatment.
So, I would prefer that we do what we are doing... We can still increase production, attempt to vaccinate all that can be vaccinated.
The problem, as Spork mentioned above, seems to currently be that there are bottlenecks in the ABILITY to vaccinate large amounts of people. Flooding more vaccine would not get more needles in arms as that is not where the bottleneck may actually lie.
Those waiting on the vaccine to be administered can remain at home and self isolate. The Biden folks re hoping that the second dose will be available as needed, when the problem may not actually be the shortage of vaccine (as the bottleneck may well be elsewhere). Once the shot is taken, especially if/when the second dose is questionable, the isolation will break and EVEN MORE will get sick.
