35-year study hints that coronavirus immunity doesn’t last long

I hope this piece is not saying that henceforth we must get both flu shots AND covid shots every year.

Since SARS-CoV-2 is a recent "human coronavirus", its ability to mutate relative to the "common cold" varieties is not yet clear.

This mutation is likely the result of errors in the proof-reading of RNA polymerase. It would seem that the new coronavirus would have to have a similar inherent mutation rate equal to those of these common viruses. Genome studies* suggest the mutation rate with the new virus is substantially lower than those of the flu virus. There is no reason to believe it will be just the same as all other coronaviruses in humans until that is demonstrated.

It sure seems that those who haven't had it and are really scared are trying their hardest to sow fear in those of us who have had it and survived easily.
