new massive covid vaccine retrospective suggests a higher than expected observation of myocarditis, pericarditis, Guillain-BarrΓ© syndrome, and cerebral venous sinus thrombosis effects in first 42 days post dose, with some differences between the different brands.
my own quick look: seems like many observed/ expected ratios fell between 1.2ish and 3.5ish, where observed would in laymen's terms still be considered infrequent and rare, but still higher than hoped.
