A conclusive and legitimate risk factor to be aware of. Very few cases considering the number of people vaccinated, but a serious risk nonetheless.
Cerebral venous sinus thrombosis.

A form of stroke.
Cliff’s note please? Twenty-five words or less?
Here is a similar US study, with the J&J vaccine:
US Case Reports of Cerebral Venous Sinus Thrombosis With Thrombocytopenia After Ad26.COV2.S Vaccination, March 2 to April 21, 2021
https://pubmed.ncbi.nlm.nih.gov/33929487/
this is pretty interesting:
“Thrombocytopenia was reported.. in none in the mRNA vaccine group (0%, 95% CI 0%-13%) and in 7/100 (7%, 95% CI 3%-14%) in the pre-COVID-19 group. 2/10 (20%, 95% CI 6%-51%) in the mRNA vaccine group [died] and 3/100 (3%, 95% CI 1%-8%) in the pre-COVID-19 group [died].”
Noone in mRNA vaccine group developed Thrombocytopenia. During the study 2 of the mRNA group died. During the same time 3 of the (control group) pre-covid group died and 7 of the AZ group died. mRNA had a better survival risk than background rate survival - 3/2.
