Unfortunately, that wouldn't really help long term, because the disease has spread through animal populations by now.
The only way to reliably stop this from being an ongoing pandemic is measures that reduce the R-value below 1 in a long-term manner, like mass vaccinations.
True. Thank you for acknowledging the point and adding further qualifications. Public discourse is rather disheartening. The options are either 100% vaccination or 0% vaccination, either strict house confinement or nightly clubbing, either masking while hiking in the woods or no masks ever. Life is a rich tradeoff of a myriad factors, somehow we reduced it to a handful of black/white binaries.
