Remarkably some scientists in Qatar working with counterparts in New York have undertaken a study asking vital questions.
They decided to study only the unvaccinated. Objectively considered, what they discovered should change the exclusively pro-mRNA vaccination policies which currently dominate the entire world. 90% of Qataris are vaccinated, but the authors tracked several hundred thousand unvaccinated individuals and studied how well they were protected from infection, reinfection, and serious Covid illness. The authors began by noting that:
“The future of the SARS-CoV-2 pandemic hinges on virus evolution and duration of immune protection of natural infection against reinfection.”
In other words: How well does natural immunity work? They found:
“Effectiveness of primary infection against severe, critical, or fatal COVID-19 reinfection was 97.3% (95% CI: 94.9- 98.6%), irrespective of the variant of primary infection or reinfection, and with no evidence for waning. Similar results were found in subgroup analyses for those ≥50 years of age.”
The authors concluded that protection at this 97.3% level will last for three years, possibly longer depending on the course of Covid viral evolution. The resounding significance of this is:
Once infected by Covid, if you are unvaccinated, you are very highly protected from serious illness even if reinfected.
