We actually do know that we can not get permanent robust immune response to COVID-19 from the vaccines that are in use because the statistics are already there,

  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).
