Intressant stor studie från CDC är nu publicerad. Enligt studien löper ovaccinerade 11 gånger högre risk att dö av Covid-19 än vaccinerade. Vidare är risken att läggas in på sjukhus 10 gånger högre samt smittorisken är 4,5 gånger högre.

Ta studien liksom det mesta från CDC med en stor nypa salt! Läs vad CDC själva skriver om potentiella brister i undersökningen.
” The findings in this report are subject to at least five limitations. First, combining unvaccinated and partially vaccinated persons resulted in lower IRR and VE estimates. Second, variable linkage of case surveillance, vaccination, hospitalization, and mortality data might have resulted in misclassifications that could influence IRR estimates; no substantial differences in ascertainment of outcomes by vaccination status were noted in jurisdictions that were able to assess this. Lags in reporting of deaths might have affected the second period differentially. Third, this was an ecological study in which IRRs lacked multivariable adjustments and causality could not be assessed (i.e., possible differences in testing or behaviors in vaccinated and unvaccinated persons). VE is being assessed through ongoing controlled studies. Fourth, the period when the SARS-CoV-2 Delta variant reached ≥50% overall prevalence was assumed to be the first week when most cases were infected with the Delta variant, but the week varied by jurisdiction. Finally, the data assessed from 13 jurisdictions accounted for 25% of the U.S. population, and therefore might not be generalizable.”
