we get a flu shot every year because there is no lifelong immunity - but we start with the base genome map & tweek it to ' fit' what will be the most common strain(s) that science believes will be going around. sometimes it works & like a couple years ago, they missed the mark bigley.
this is a 'novel 'virus, so we don't even have a base to work with yet that is known how it behaves. AND, even if we do get a vaccine, that doesn't mean that we will be safe years down the road. think, chicken pox & shingles.
That's because the flu changes year to year, not because or Immune system doesn't remember it.
There is no evidence either way if COVID is cyclical or constant when it comes to mutation rate.
