As it is, I expect we'll eventually need a booster shot, and fortunately Moderna (and Pfizer) are working on one.
At the rate COVID is mutating, I will not be surprised if the booster shots become an annual, or even semi-annual, ordeal similar to the influenza shot. It is a virus after all, and mutation is a viral thing.
I'm not surprised either. Given that the booster shot would be mainly in response to these new variants, I would think, though, that after our booster shot for the Moderna vaccine, a permanent vaccine would be the norm for COVID, and thus that would just be another one my wife and I would get every year. As it is, we always get the one for the flu (high dosage variety) as soon as it becomes available, typically in August or September.
