This is based on data from 22-3 (so 2 weeks old), now there is almost twice as many cases. They estimate reporting rate 1-2 in 100 000. They've compared it to anti-conceptive pills which have incidence rate of blood clots 4 in 10 000. They've asked AZ to look into the clinical trials (both closed an ongoing) and to try to find the mechanism of interaction of vaccine with the clotting system in the lab. They have extensively considered that it's caused by intravenous application instead of intramuscular and rejected it due to small amounts. Similar concerns for J&J surfaced in the clinical trial.
