I think it is both. The mRNA vaccine immunity did not wane just because of changes in the virus. That was probably a factor but in this case I don't think it was even the biggest one. The immunity just wanes, even to the same strain. It is to do also with the immune system itself.

The antibodies produced by any vaccination series wane, it isn't a surprise that it happened with the COVID vaccines. The mRNA vaccines do induce memory T cells, which is exactly persistent immunity, so the immunity doesn't 'just' wane.

Repeated doses of the vaccine broaden and increase the antibody response, so of course it makes sense to encourage them when infections are raging, and an annual booster will induce an antibody response, providing increased protection for a period of time, so of course it makes sense to encourage them, especially for more vulnerable people.

This inability to look at things in a sort of probabilistic sense, where things can be good without being perfect, is incredibly damaging.

If that was so then things like alergies and autoimmune diseases wouldn't be for life
