One of the government's databases for storing post vaccination adverse events is called VAERS. It's been storing information for 30 years for all vaccines administered.
Of all post vaccination seizures recorded for 30+ years, 69% have been reported for the Covid 'vaccines.' Most adverse events are never reported to VAERS, so this is just a sampling of occurrence.
If I isolate only the bivalent Covid 'vaccine', it's displayed with the other vaccine taken so the chart looks messy as both that other vaccine and the Covid 'shot' are each awarded 1 'count' on the total.
Since the bivalent was trialed only on mice, not humans, I don't see a reason to expect improved safety, but YMMV:
