Reply to comment by SteakandTrach in New evidence suggests that ‘hybrid’ immunity, the result of both vaccination and a bout of COVID-19, can provide partial protection against reinfection for at least eight months. Immunity acquired by booster vaccination alone seems to fade somewhat faster. by MistWeaver80

Ya...those coronaviruses became "colds" over the course of millennia...

I don’t think anyone really knows when they did this. Could have been millennia, could have been the 1600s. That’s paraphrasing the virologist that gave a CME lecture on COVID I attended 2 days ago.

Well pretty safe to say it wouldn’t be in our lifetimes if we just wait for it.

There is a theory that one of the cold coronaviruses was the origin of the 1889 pandemic. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8441924/
