+===== Examination of All-Cause Mortality Risk =====
   * [[Columbia University]] research [[:Spiro Pantazatos]] and colleague [[:Herve Seligmann]] produced [[https://www.researchgate.net/publication/355581860_COVID_vaccination_and_age-stratified_all-cause_mortality_risk|a study]] showing an association between greater COVID-19 vaccination and higher all-cause mortality.

An extremely detailed Substack piece from Orwell2024. Among the many conclusions are; 1) 2020: The age adjusted mortality demonstrates the overreaction in the Covid-19 crises; 2) 2021: Neither a positive nor negative impact of the vaccine can be seen; and 3) The observed excess mortality in Austria and Netherlands is dominated by mortality in the elderly age bins. Those are 95% vaccinated like in Sweden, Spain and France. The vaccine doesn’t reduce nor increase all cause mortality. It isn’t the underlying root cause. QR passports and the one dimensional panic driven C19 health focus has to stop.

+===== Data Controversies =====
+Official efficacy calculations often skip the first 10, 12, 14, or 21 days before computing efficacy. But those days cannot be skipped in a risk-benefit analysis (or in real life), and what happens during that span could be dangerous.((September 15, 2021 | el gato malo | [[https://boriquagato.substack.com/p/why-vaccinated-covid-deathshospitalizations?s=r|why "vaccinated covid deaths/hospitalizations" are being counted incorrectly]]))
 COVID-19 vaccine data discussions have been made confusing if not outright fraudulent by the unclarified or misclarified use of data categories such as intervals "first 14 days after dose 1". It is unclear the extent to which such categorization has been used, intentionally or otherwise, to rig vaccine efficacy statistics, but the effect is undisputably large when such miscategorization takes place.
