According the recent study, so-called natural immunity continues to offer greater protection against severe illness than the COVID-19 vaccine.
Researchers in Qatar discovered that non-vaccinated individuals who recovered from COVID-19 infection had extremely strong protection against severe or fatal COVID-19.
“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.”
After researching long-term natural immunity in unvaccinated individuals, Dr. Laith Abu-Raddad of Weill Cornell Medicine-Qatar and colleagues reported similar findings in sub-group analysis for those under 50 years of age.
