Getting COVID twice

With the mounting breakthrough cases and the undeniable evidence that the vaccinated are much less likely to develop severe symptoms, my question is: What about the unvaccinated that get COVID a second time? Is there any evidence that they are less likely to develop a severe/life threatening case?

PS. Unless contraindicated, I think that everyone that can get the vaccine should. Full stop.

Since this is already being discussed in another thread, let’s close this one.
