My husband and I both received the "new" Covid vaccinations on Friday (October 13) and I ended up in ER at University of Colorado on Saturday (October 14) --- I thought I was having a stroke, could not recall items in our house, could not recall the route to ER (our daughter-in-law came from Florida to help and did not know the way, and I was of no help even though I have been there before). Very disturbing were the "crackles" all over my head. Our daughter is a physician and recommends that I not be vaccinated again. My husband had almost no reaction. Had it not been for the Bandaide on his R arm he could not have told me which arm he received the vaccination. What is this??
