PRE-VACCINATION, death RATE from COVID-19 infection in non-elderly. But then, WHY?

13 Ottobre 2022 by

… The infection fatality rate (IFR) of COVID-19 among non-elderly people in the absence of vaccination or prior infection is important to estimate accurately

… since 94% of the global population is younger than 70 years and 86% is younger than 60 years

… 31 systematically identified national seroprevalence studies in the pre-vaccination era

… median infection fatality rate of COVID-19      [ median IFR ]  :

… 0.0003% at 0-19 years

… 0.003% at 20-29 years

… 0.011% at 30-39 years

… 0.035% at 40-49 years

… 0.129% at 50-59 years

… 0.501% at 60-69 years

… At a global level, pre-vaccination IFR … 0.03% and 0.07% for 0-59 and 0-69 year old people, respectively

… excess death calculations show no excess deaths among children and adolescents during the pandemic

… even in the wild strains that dominated the first year of the pandemic, the IFR in non-elderly individuals was much lower than previously thought
