I don't think the usual risk factors for clotting apply here. These cases were rare enough to stand out at just 1 per million. The clotting seems to be a specific immune response similar to some people who clot when given heparin.

FWIW, the ACIP meeting today shared that another ~7 cases were discovered. In a particular group - women between 30-39 - the numbers were more like 1 in 100k. Still very small odds, but greater than the "one in a million" widely quoted, particularly for certain age groups.
