Corona Vaccination Saved Many Lives in Austria

Uwe Riedmann from MedUni Vienna and his co-authors, including Martin Sprenger, published their study in the "Journal of Infection." They examined non-Corona mortality in vaccinated and unvaccinated individuals to accurately assess the vaccine's effectiveness. The research was a retrospective observational study of the adult population in Austria with Corona infection, covering the period from 2021 to 2023.

Initially High Bias

Initially, the scientists demonstrated a significant bias in overall mortality from all causes in the temporal context of the Covid-19 vaccination. "Among 4,324,485 individuals eligible for vaccination, the differences in non-Covid-19 mortality risk between vaccinated and unvaccinated individuals were strongest in the short term (after immunization; note) and decreased thereafter. Analyses for the first two weeks after vaccination showed a reduction in mortality risk to below 0.5 for vaccinated individuals compared to unvaccinated individuals, regardless of the number of immunizations (vaccine doses; note)," the study states.

However, after a period of two weeks, the mortality risk between the two groups (individuals with a past Covid-19 infection and subsequent vaccination or lack of immunization; note) equalized again. The likely reason: In Austria, proportionally more people with good health status were immunized. On the other hand, the experts noted: "Covid-19 deaths were significantly reduced among immunized individuals (by 26 to 53 percent)." This protective effect was again greater during times of high Covid-19 case numbers.
