> projections out to at least a year
You're right - I should have said "periodic vaccination", not annual.
Also yeah, there's a subtle difference between why we'd need periodic covid vaccinations vs flu vaccinations. But in the end the result is the same, we'll probably need to be re-vaccinated against covid over time.
Covid isn't going away because it has a non-human animal reservoir, so it's all about a strategy to prevent it's re-emergence into the sapiens reservoir. It's possible that periodic vaccinations of the population as a whole would be overkill and we could reactively immunize smaller populations as re-infection occurs.
