Parallelizing calls without synchronicity problems
Those are likely the most tested vaccines in history.
We're suppose to be able to do things like this in order to save ourselves. Imagine if COVID was deadlier, had a higher R-naught, etc. Would you still be advocating for "taking it slow"? If hundreds of thousands were dying per day should we still be waiting years for a vaccine?
You can also laud the mrna vaccines and be critical of the obscene profits being made.
In fact, you can also promote vaccinating as widely as possible, and at the same time harshly condemn the politicization of medicine, the creation of second class citizens, and the nonsense power games being fought that seem to exclusively benefit massive corporations that fund political campaigns.
I think even with a 10% CFR, there'd be droves of vaccine skeptics, unless the virus hits people with more or less uniform symptoms.
...or maybe it even has nothing to do with lethality at all, look at the ebola vaccine rollouts in Africa.
They were also handled with an abundance of caution, which is why many countries suspended the Oxford vaccine after initial reports of adverse effects in young women despite the extremely low frequency hinting at sampling bias rather than genuine side-effects.
