The strain of flu changes significantly enough our immune system doesn't know what to do with it. COVID, even with the variants, has remained close enough to the original that the vaccine should let the body recognize all the variants. Those that had COVID should remain immune for several months, but may not recognize any variants. At least according to resources like Arstechnica and similar.
