Clinical course: The patient stated that it's kind of been a long 2 years for her and it was not really plainly obvious that, she was having some issues that she feel that those were from the Covid vaccine (clarified as Pfizer Covid19 vaccine). She had two shots in Apr2021, the primary in the beginning and then 3 boosters. She had the first two, the primary vaccine was given by the board at a college in next town and then the 3 boosters were all at a pharmacy. It didn't really made sense to her until this past Dec2022. She had been in the dental office since Apr2022 because of an autoimmune disorder called Lichen Planus. So usually for the last 2 years, it had attacked her mouth tissue, the mucosa and this 'part' fall in September (no date reported). She had been to numerous doctors and one doctor that said that they did agree that it's possible that it could have been from the vaccines. She had been to a dozen of doctors and she don't really know for sure, if it could be the vaccine but it's pretty obvious that when she had the vaccines, and the boosters she had the autoimmune disorder. She also stated that this also affected her hearing and inner ear so, sometimes she don't get everything that's been said and it will cause like a sharp pain in her inner ear so if she stop talking and will interrupt. She had the Flu shot in 14Sep2021 from Sanofi. Then had the Covid19 first booster in 22Oct2021 and that was Pfizer. Then 2 more boosters in 2022 was 02Apr2022 at (name withheld) and that was Pfizer and then the 24Sep2022 was also Pfizer. Patient further stated, "And do you need to know about the one from 2022 because it got worse it was worse". She meant she was losing her hair, nose bleeding, staggering, couldn't hear, hallucinating. Name a symptoms and she stated that she probably had it. She went to ear, nose and throat and they didn't see anything. She went to neurology, they don't know. Then she started one in her fingers and her nails. She went to the dentist because her mouth was completely infected, it was filled with lesions.  The information on the batch/lot number for BNT162b2 has been requested and will be submitted if and when received.
