Vaccine immunity IS "natural" immunity. It works the same way, by exposing the body's immune system to virus components such that they product a response. The only difference is that with a vaccine those components don't add up to a viable organism.
But yes: expect newer vaccines tailored to currently-circulating strains to appear; the existing mRNA vaccines produce copies of the spike protein sequenced more than a year ago. That's what we've done for influenza for decades, though not with the same kind of precision.
