the dynamic is a feedback loop in either direction. More vaccinations means slowdown of spread which means slower rate of mutation and in turn easier ways to control the virus. Faster transmission means faster rate of mutations and having a harder time controlling the virus.

'Zero covid' or near-zero covid anyway does not 'reek' because it is perfectly attainable. The virus could be squashed pretty much completely. The fact that we cannot do it is the result of institutionalized failure, resignation and normalization of dysfunction, not actually a matter of fact.

We have in fact eradicated one highly transmittable, airborne virus through a global vaccination effort already, namely smallpox. And that was almost half a century ago.
