To which degree is this statistic confounded by the Delta mutation emerging?

The original strain upon which the current vaccines are based has basically died out and Delta carries a lot more viral load (400x or so?), which changes the game a bit.

In comparison, smallpox virus was pretty much the same across centuries, so it was comparably easy to target and eradicate. No animal hosts helped, too.

Covid-19 is impossible to eradicate as it spreads through animals, forget that idea.

Pfizer themselves have performed studies that show immunity declining. I do know that they tell from the levels of antibodies seen in blood but I don’t know if the effect of variants has been measured (if it can be measured at all without unethical experiments).
