I am not sure what discussion you are trying to have. I just quoted something that has been published by our own government about the Jansen vaccin. I was not claiming one vaccin being more effective than the other (I couldn't care less actually).
It was about how realistic it was to have the entire dutch population over 18 vaccinated before July 1st. And with 11 million doses of Jansen...I guess it is realistic since you only need 1 dose.
Anyway...EMA says this:
The trial found a 67% reduction in the number of symptomatic COVID-19 cases after 2 weeks in people who received COVID-19 Vaccine Janssen (116 cases out of 19,630 people) compared with people given placebo (348 of 19,691 people). This means that the vaccine had a 67% efficacy.
