“once Omicron displaced Delta, the “pandemic” ended”
Omicron moved like wildfire through the population. I saw one estimate that 3/4 of Americans have had it already (including me).
When you layer on top everybody who had the earlier strains, and all the vaccinations, there is pretty thorough herd immunity out there.
Hopefully, it will be durable.
Hopefully, we'll have enough immunity so we won't see any more surges. It'll still be around but with a low level of activity like now. The fear is that immunity is not lasting and that it wears off quickly. We'll find out soon.
