COVID spike proteins alone can cause COVID-like illness, without an active infection.
Please note that this was discovered in mice, and the spike proteins were injected, not inhaled.
One implication is that COVID vaccinations that cause cells in the body to produce spike proteins may be causing illness in the same way. And perhaps not just in vaccinated people, if spike proteins are being shed by the vaccinated.
Another implication is that there may not have been nearly so many active infections during the pandemic as we thought.
It appears from a cursory search that some COVID tests will come back positive based on spike proteins alone, although the ones in the vaccines are probably different enough to not be detected.

"It is not meet to take the children's bread, and to cast it to dogs," Jesus said; Matthew 15:26.
I recently understood that I am spending my life in rebuilding spiritual and practical foundations that had been foolishly undermined by previous generations.
Several months ago I was reading a nonfiction book by Christian author Paul Tournier, and made it about three-quarters of the way through before being drawn away to other things.
When I picked it up this last week and finished reading it, I found references to about a dozen Bible passages that had come up in my daily Bible readings in the interim, mostly obscure Old Testament personages with a variety of afflictions; Tournier was a Swiss doctor famous for connecting his Christianity with his medical practice.
I also read a Christian fiction book this last week: Deadline, by Randy Alcorn. One day, what I read in the book mirrored my morning Bible reading on that same day.
"A work of creation was three-fold, an earthly trinity to match the heavenly; the Creative Idea, timeless and passionate, which is the image of the Father; the Creative Energy, begotten of the idea and working in time, which is the image of the Word; the Creative Power, the meaning of the work and its response in the individual soul, which is the image of the indwelling Spirit."
