Restrictions being placed on unvaccinated individuals with natural immunity is based on the premise that it's not as effective or long-lasting as the vaccine. That might not be an excuse to not get vaccinated, but it's absolutely a reason that individuals with natural immunity should not be treated any worse or differently than vaccinated individuals. Regardless of whether vaccination improves on extant natural immunity. And based on what we know about sars-1 and mers, that's not necessarily a safe assumption. For cases of repeated exposure and vaccination over time, the problems with those vaccine attempts were primarily over-stimulating an immune response.
