One of the questions asked early on with COVID19 was how we managed to end the Spanish Flu 100 years ago without vaccines. When I saw this question posted it was typically met with shrugs and "not sure".

I think Omicron offers a possible explanation. An even more infectious variant with lower mortality should out-compete the deadly variant over time. After a few mutations like that it should be no worse than the seasonal flu--which has its own death toll each year, remember.
