Once all the kids are vaccinated (and BTW even the WHO is taking a cautious approach on this given that it's unclear whether young children are at more risk from Covid or the shots), what's the plan for preventing variants from developing in the developed world? In animal reservoirs? In the large numbers of vaccinated people who still wind up hosting (usually minor and asymptomatic) infections?

If vaccine escape happens because the UK had its schools open then I find it very difficult to believe "we vaccinate everyone at once and the virus just goes away" was ever a realistic prospect in the first place.

From what I understand, there is a good chance that the pool for variants is limited, and that vaccinations (or a past infection) give decent immunity for new variants. Even for a variant with an immune escape, ie. you are not immune and might even spread it, your past exposures will make a serious case with hospitalisation unlikely. Immune escape is not a boolean attribute.
