Relative Effectiveness of Covid 19 Vaccines

A common question is, which of the several alternative vaccines to choose. The answer is not simple, as it depends on what criteria you set for determining what's best - everything is a matter of definition. Furthermore, the stats change as time passes and more data becomes available.

So I found this latest, well documented comparison, dated Nov 19, 2021, according to which Moderna seems to have the edge at present, overtaking Pfizer which held this distinction some time ago.

The above for those about to take the booster dose and trying to decide which vaccine to go for.
