Jan 9, 2023 · One study found that one-dose hybrid immunity with either ChAdOx1, BNT162b2, or mRNA-1273, was associated with a 58.0% lower risk of SARS-CoV-2 reinfection than natural immunity for up to 2 months, with evidence of attenuation thereafter up to the 9-month follow-up.
Jan 24, 2022 · “The most direct conclusion is that for the Delta, and possibly the Omicron, natural immunity confers very strong protection,” said Dr. Iahn Gonsenhauser, the chief quality and patient...

Oct 28, 2021 · While vaccinations are highly effective at protecting against infection and severe COVID-19 disease, our review demonstrates that natural immunity in COVID-recovered individuals is, at least, equivalent to the protection afforded by complete vaccination of COVID-naïve populations.
Feb 16, 2023 · Past infection with pre-Omicron variants provided substantially reduced natural immunity protection against reinfection with Omicron BA.1 (36% at 10 months after infection).
According to an analysis published in The Lancet Infectious Diseases, a recent, robust study shows that hybrid immunity is longer lasting and more effective than disease-induced immunity or vaccination alone. The analysis reviewed 26 studies that examined protection against reinfection, hospitalization and severe disease caused by omicron.
Nov 21, 2023 · Natural immunity conferred substantial protection against COVID-19-hospitalization. Cohort 2—in comparison to natural immunity hybrid immunity offered strong protection during the...
