I personally know 3 elderly folks(2 in their 80’s). All 3 received their boosters - all 3 suffered seizures within 2 - 3 weeks. All 3 were diagnosed with encephalopathy. 2 have since died from this disease. 1 is in bad shape.
I don’t think I’ve ever heard of any acquaintance dying of this prior to this last month. There is a known link:

Just in case it isn’t clear to you, encephalopathy refers to any kind of brain problem (basically). Surely you have heard of people dying from brain pathology. I am sorry to hear about your acquaintances.
