Result per vaccine
Five weeks after the first vaccination, the risk of hospitalization after infection decreased by 85 percent with the vaccine from Pfizer / BioNTech. For AstraZeneca’s, the rate in the study was 94 percent.
This makes the AstraZeneca vaccine seem to work better against severe covid-19 disease than it prevents the disease. The European medicine watchdog EMA concluded that this vaccine offers protection for 60 percent of people. For the Pfizer / BioNTech product, the percentages were closer together: according to EMA, the product protects 95 percent against covid-19.
The full results of the investigation will be announced later. This will also show what the effect of the second dose is, and what effect vaccination has on the mortality rate.
