Additional Information: The patient has called Pfizer before, once was earlier this morning and she got no help and was told to go to the website to look up the side effects, but that was no help either. The patient had her 2 initial Pfizer shots around 2021 (also reported as Oct2021) and then her first booster and then two weeks ago (Jul2022) she had her second booster. After a week and a half of getting the second booster, the patient felt yucky, tired, and a little under the weather. On the second day where she didn't get out of bed all day, the patient was unable to eat, and was also nauseous. By the third day, the patient said she was better and at the end of that day, she already felt good. On the fourth day, she was already back to normal. For the first 2 doses, the patient felt thrilled because she was lucky, she didn't have any problems with the first and second doses, however, she didn't realize that she also has other problems that don't go away, and they might be caused by the vaccine because she had read some of the other people's side effects online. The information on the batch/lot number for BNT162b2 has been requested and will be submitted if and when received.
