Study finds people have short-lived immunity to seasonal coronaviruses

I'm not an epidemiologist either, but to this layperson, the viruses studied seem to have been chosen on criteria that select for short-lived immunity. It seems likely that "seasonal" viruses, viruses "that regularly circulate to cause the condition we recognize as the common cold" must induce short-lived immunity.

Would it be possible for a virus that induced long-lived immunity to be seasonal, reoccurring year after year?

And why were the other coronaviruses that infect humans left out of the study?

Because one of them, SARS-1 went extinct in just over a year due to a heroic international response, and the other, MERS, has about a 35% fatality rate and is unlikely to be found in anyone who does not have direct contact with camels.
