This exact thing happened with the AstraZeneca vaccine, which works very similarly to J&J. The EMA is now recognizing thrombocytopenia (not the same fatal issue but possibly related) as a "common" side effect, i.e. somewhere between 1 in 10 to 1 in 100.

I suspect that, as soon as we start looking for blood clotting post-vaccine, then you'll find more cases that may have not been caught otherwise due to their not being severe enough to be noticed.
