What if immunity to covid-19 doesn’t last?

Researchers say people can catch mild, cold-causing coronaviruses twice in the same year. For the coronaviruses “immunity seems to wane quickly,” says Jeffrey Shaman, who carried out the research with Marta Galanti, a postdoctoral researcher. The big question is what this fizzling, short-lived resistance to common cold viruses means for covid-19. Is there a chance the disease will turn into a killer version of the common cold, constantly out there, infecting 10% or 20% of the population each year, but also continuing to kill one in a hundred? If so, it would amount to a plague capable of shaving the current rate of world population growth by a tenth.
