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.
Feb 16, 2023 · For people who have been infected with COVID-19 at least once before, natural immunity against severe disease (hospitalisation and death) was strong and long-lasting for all variants (88% or greater at 10 months post infection).
Apr 20, 2022 · We found that, before the emergence of the omicron variant, natural immunity provided a similar degree of protection against COVID-19 infection as mRNA vaccination.

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.
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...
Hybrid immunity = natural immunity + vaccination. 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.
May 28, 2021 · Immunity from natural infection starts to decline after 6 to 8 months. We know that fully vaccinated people still have good immunity after a year—and probably longer. Why is it that the vaccine leads to better immunity than natural infection? The honest truth is, we don’t know.
Nov 21, 2023 · Our study showed that natural immunity offers stronger and longer-lasting protection against infection, symptoms, and hospitalization compared to vaccine-induced immunity.
