This report shows that modeling claims, based on a novel mathematical construction (Ψ), that unvaccinated people disproportionately contribute to the infection risk of vaccinated people are rigorously incorrect.
The report is published both by CORRELATION, and here: https://pubpeer.com/publications/3ACB55309DB4EF7D3518A4A5B2B65E#2
The incorrect claims were made in the April 2022 article “Impact of population mixing between vaccinated and unvaccinated subpopulations on infectious disease dynamics: implications for SARS-CoV-2 transmission” by Fisman et al.
Hickey and Rancourt’s previous criticisms of the Fisman et al. article are listed below:
