The Omicron wave is what killed the pandemic so it was a net positive. Nature ran (is still running) its course.And we did not have it either until we did. Our last booster was about 9 months ago, so possibly a booster after 6 months could have saved us.
We take ballroom dance lessons and attend a dance party every Friday evening. I can’t think of any other activity that one does in public that would be more conducive to transmission than spending 3 minutes with multiple partners with the head about 1 foot away from another person and holding one or both of their hands.
Edited to add: practically everyone we know contracted it during the Omicron wave.
