section...the study is from April, 2021...before the Delta variant became the dominant cause of COVID cases (98%) on or around July of 2021...and prior to the CDC study(October, 2021) that I presented...
"These data suggest that naturally acquired SARS‐CoV‐2 immunity does not wane for at least 10 months post‐infection. However, the applicability of these studies to new variants or to vaccine‐induced immunity remains uncertain."
I'd like to see a more recent study from the authors of what I believe was an Irish Health Ministry study, published by Wiley (or any others)...I'd also like to see studies that have been peer reviewed by such notable sources as the NEJM, or Nature...can you ask Dr. Risch for such studies?
