Unfortunately , similar situation with Elderly mother and rest of my immediate family (except for myself and two young sons). Mother diagnosed with sudden onset Alzheimer's/ rapid cognitive decline in 6 months of first two primary doses. Both sister and Mother hospitalized three weeks to the day after 1st booster - dangerously low White blood cell counts - Doctors baffled - no idea - sent home with paracetamol follow up with Gp - he has no idea. Young adult Neice - heavy / random/ incessant woman bleeding - no idea must be a woman thing - put on hormonal iud - ugh. All of the above and eldest brother (couple years out of chemo / surgery for colon cancer) have constant cough/ malaise and frequent bouts of feeling unwell/ tied/ run down etc. They are all baffled and prefer to remain totes ignorant.

I know the feeling.
