Natural immunity offers overwhelmingly high protection against severe COVID-19 reinfection more than a year after initial infection, according to a new study out of Qatar.
The Epoch Times reported that the paper, published last week as a preprint, found that “[e]ffectiveness of primary infection against severe, critical, or fatal COVID-19 reinfection was 97.3 percent” with “no evidence for waning,” and similar findings for those age 50 and older.
The researchers also found that natural immunity is less effective against contracting Omicron, the least-severe variant of COVID, though still more effective than the immunity offered from the COVID vaccines.
Overall, they concluded, “[p]rotection of natural infection against reinfection wanes and may diminish within a few years. Viral immune evasion accelerates this waning. Protection against severe reinfection remains very strong, with no evidence for waning, irrespective of variant, for over 14 months after primary infection.” Read more…
