1. No point vaccinating those who’ve had COVID-19: Findings of Cleveland Clinic study
Scientists from the Cleveland Clinic, USA, have recently evaluated the effectiveness of coronavirus disease 2019 COVID-19) vaccination among individuals with or without a history of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.
The study findings reveal that individuals with previous SARS-CoV-2 infection do not get additional benefits from vaccination, indicating that COVID-19 vaccines should be prioritized to individuals without prior infection. The study is currently available on the medRxiv* preprint server.

Big fat duh. Nominally, one would think that the natural immunity conferred by a previous infection constitutes more elements of the characteristics of the virus than just its spike proteins, which is all the mRNA gene-manipulation shots are designed to target. I should add that I believe the tech is very interesting and doubtless will have much application going forward. But as a global "emergency" experiment? Meh.
