Learned that there is a list of chemicals in the injection caller never heard of before, just the 1st chemical listed that caller could understand is potassium chloride, if caller had known potassium chloride was in the injection caller never would have accepted the injection.

Since having the vaccine caller has an extremely high number of white blood cells in urine without an infection.

New event added.  Agent: Caller wants to know if there is a doctor in the state of (State name withheld) for treating people in regards side effects she's experiencing due to the Pfizer-BioNTech Covid 19 Vaccine. She has extreme allergies to preservatives and medications. Once speaking with the caller, she mentioned that 48 hours after receiving her fourth dose of the Pfizer-BioNTech Covid 19 Vaccine she has been experiencing inflammation and horrible pain. They never told her about the inactive ingredients of the vaccine, and she believes those ingredients are the reason of her side effects. It has been 6 weeks since she received the vaccine and she's still in horrible condition. She requires a pharmacologist or a specialist (located in the state of Withheld) regarding the inactive ingredients of the vaccine that could help her understanding the pH and how long the inactive ingredients are going to be in her body. Once patient sent her the document CONS-What are the functions of each ingredient in the vaccine, she stated that she doesn't remember that these ingredients were in her second or third dose. She can't sleep, eat or drink because of her side effects, stating she feels like "crap". She mentioned she has medical condition and also has heard that people have died because of the vaccine. She would like the reports of people that have reported similar adverse events as her to make a decision of what type of treatment would be the best for her. She knows that some universities are doing research with the reported adverse events of the vaccine and would like to know which universities are doing it.   The information on the batch/lot number for [BNT162B2] has been requested and will be submitted if and when received.
