This is a truly incredible result for the following thing that might get lost on first glance -
The 90%+ efficacy is not compared to NO vaccine, it’s compared to a 2-dosed population.
The step UP in immunity is relatively as much as getting 2 doses when you had no immunity.

If getting two doses of Pfizer reduced your chance of death or sever disease by 20X (round number but largely accurate), this reduces that risk a FURTHER 20X.
Now, the immunity has waned a bit in the 6 months since your second shot, so maybe it’s only 4X or 5X, but add 20X!

Now we’re talking about reducing the risk something like 100X. Really approaching 99% overall efficacy.
This is the kind of efficacy that is nearly miraculous.
