Could the Covid-19 Vaccine become a yearly-Shot? – Some Experts think so

Depends on variability. Lots of flu shots due to fessing on prevalence. If natural immunity lasts for covid, fine, but if it’s too flu like there’s going to be a need for shots. We’ll see it develop in real time.

So far, there’s no evidence of a sterilizing vaccine or a once and done infection process.

I don't think this is in any way a viable long-term strategy. I think the vast majority will develop resistance or immunity which most people already seem to have. Maybe the other group need a preventative, but a yearly shot is unrealistic.
