She got her second shot on 03Apr2021. Had a stroke on 18Apr2021. After all the tests and everything, the neurologist found there was no medical reason why she had a stroke. She had no buildup. Her cholesterol was really low, it always has been. Everything always worked, she had no high blood pressure. A year went by, she pretty much recovered from the stroke. She got the booster shot for the COVID-19 Vaccine. The reason she's getting the shots regardless of her health is because her husband has heart problems and cancer. Husband is on drugs for both of those conditions, and he has a very low immune system. Caller was in the hospital. She never had high blood pressure. She was usually 120s / high 70s-low 80s. A small balance problem is the only residual problem. Her left side doesn't like to stand up straight. She was admitted to the hospital for seven days. Never in her life has she had high blood pressure. Everyone keeps saying she's getting old, but high blood pressure doesn't just appear, something is causing it. Her being 70 years old doesn't give her a lot of credibility in the medical field. She crawls around on the floor and has mobility like a 30-year-old, she plays street hockey. She is not just sitting up in her rocking chair folding up and dying. The worst problem beside the drugs for the high blood pressure medications not working is the side effect where all of her muscles just roll up in a big, huge ball and she has to un-ball them every morning. Clarifies she has to exercise before she even goes to the bathroom, she can hardly get up. She doesn't understand it, before the stroke happened there was absolutely nothing wrong with her, except she had hypothyroidism and has been taking thyroid medication for 30 years. The only pill she took was levothyroxine. All doses were manufactured by Pfizer, States her hospital records says she has had 4 total COVID-19 Vaccines. But if she has had 4, she never endorsed the last one, it must have been snuck in with her flu shot. Does not have vaccine record card at time of call to provide NDCs/LOTs/EXPs or other product details.   The information on the batch/lot number for BNT162b2 has been requested and will be submitted if and when received.
