Sorry I thought you meant where's our immunity to covid, to which I answered it is evidenced by the people who are infected with SARS-Cov-2 and test positive but don't develop symptoms.
Our population immunity to the common cold-causing coronaviruses is evidenced by the lack of covid-style outbreaks and resulting excess deaths that would otherwise be caused by these particular coronaviruses, if we had a lack of population immunity to them.
You're just making stuff up.
