Some already do evolve to evade this, this is why the flu vaccine changes every year
But this is not a vaccine (triggering an immune response to a specific antigen) despite the headline, it’s a way to dial up the (entire? it’s unclear) immune system. Seems like a good way to evolve superbugs and get nasty autoimmune conditions.
