I haven't seen any news articles provide a point of comparison of how the number of people receiving the J&J vaccine and experiencing this particular kind of clotting. The first academic-ish article on the subject I could find indicated a typical baseline of 15.7 cases per million (https://www.ahajournals.org/doi/full/10.1161/STROKEAHA.116.013617 https://www.ahajournals.org/doi/full/10.1161/STROKEAHA.116.0...). If that's true, I don't get it - why would we stop roll out of any vaccine when the baseline (15.7) is higher than the problem that is being claimed (1 per million)?
