The common cold and the yearly flu are both corona viruses. They mutate all the time. That's the reason for the Indian, African, and Brazilian strains of Covid.
It's my guess that we will need a yearly Covid shot just like a flu shot. I just hope they guess better with the Covid than they seem to do with the flu shot.
BTW, my wife and I had no real after-effects from the Moderna shots except for soreness at the injection site and that only lasted one day. My kids, however, had reactions for several days. They are in their late 30's.
I think we old farts have probably been exposed to something similar in the last 70 years that keep the reactions down.
