Ware the confounders. https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(21)00475-8/fulltext Reading the full paper, we find 1.9% of unvaccinated Alpha infectees required hospital admission. 2.2% of unvaccinated versus 2.3% of vaccinated Delta infectees required it, and 3.4% of vaccinated Alpha infectees required it. Thus, strangely, vaccination appears in these findings to increase the risk of hospitalization or emergency treatment required. The statistical power of these findings isn't very great because of too few hospital admissions amongst vaccinated infectees, and bear in mind we vaccinated people at higher underlying risk first and more thoroughly and the propensity of people who have been vaccinated to also be more l...
