A lower relative incidence of short-term deaths following COVID-19 vaccination support that COVID-19 vaccination is not associated with the observed excess mortality. (5/5)

In comparison, we observed a 16-fold higher incidence of all-cause deaths in the three weeks following a registered positive SARS-CoV-2 infection compared to more than three weeks after infection (IRR 16.19, 95%CI 15.78–16.60). (4/)

We found a 44% lower relative incidence of all-cause deaths in the first three weeks after the primary vaccination compared to more than three weeks after vaccination (IRR 0.56, 95%CI 0.54–0.57). (3/)

I"Het is waar dat geen enkel gesprek perfect is en dat er altijd een risico is dat een discussie uit de hand loopt. Daarom is het nodig dat de universiteit zorgt voor ondersteuning om veilige klaslokalen te creΓ«ren waarin gepassioneerde docenten en open-minded studenten met elkaar in gesprek gaan."
