People who survived COVID-19 infection and were not vaccinated had sky-high protection against severe or fatal COVID-19, researchers in Qatar found.

Effectiveness of primary infection against severe, critical, or fatal COVID-19 reinfection was 97.3 percent … irrespective of the variant of primary infection or reinfection, and with no evidence for waning. Similar results were found in sub-group analyses for those ?50 years of age,” Dr. Laith Abu-Raddad, with Weill Cornell Medicine-Qatar, and colleagues said after studying long-term natural immunity in unvaccinated people.

That percentage is higher than the protection from COVID-19 vaccines, according to other studies and real-world data.
