Clinical narrative: This is a spontaneous report received from a contactable nurse (patient) via a Pfizer-sponsored program. A 62-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, lot number: EN6206), via an unspecified route of administration in the right arm, on 10Mar2021, as 1st dose, single, for COVID-19 immunisation. Medical history included ongoing fibromyalgia (diagnosed in 1996), ongoing allergies from 1981, ongoing food allergies and chemical allergies, ongoing allergy to alcohol, ongoing hypothyroidism from 2012, ongoing pre-diabetic from 2012, Lyme disease for 11 years before being correctly diagnosed and treated, concussion in Sep2019, and post concussion syndrome in Sep2019. The patient previously took nalbuphine hydrochloride (NUBAIN) in 1981 and experienced anaphylaxis; and paracetamol (TYLENOL) and was very sensitive, had rash and high blood pressure. Within the first 15 to 20 minutes following the administration of the first dose of the Covid-19 vaccine, on 10Mar2021, the patient's face and ears got very red, flushed, and itchy. The patient reported that she is allergic to alcohol and thought maybe it was the glycol in the COVID-19 vaccine that caused the reaction. She reported that she has had glycol before and has never reacted quite like that. The flushing, redness, and itchiness of her face and ears subsided within an hour and were gone by 4 hours. Her allergist instructed her to take 2 Zyrtec before getting the second dose of the Covid-19 vaccine. After her face and ears became flushed, red, and itchy, she ended up having a really bad headache that continued until the next day. Her headache was severe for about 12 hours and continued for a total of a day and a half.  She stated that her headache was more like a migraine during the 12 hours when it was severe. It felt like a migraine, but worse. On 10Mar2021, the patient reported that she experienced flu-like symptoms like being nauseous, had dizziness, achiness all over, and was not feeling well, her post-concussion syndrome was triggered and had more headaches, dizziness, nausea. She reported that things have been going awry in her body since she had the COVID-19 vaccine. She reported that the increase in headaches seemed to have improved, but the nausea and dizziness have in some ways improved and then some days it feels like "here we go again" when it hits. About a week after she received the first dose of the Covid-19 vaccine, in Mar2021, the patient noticed a change in her urination. It wasn't severe or anything at that point, she just felt like she was not able to release the urine (urine retention). She thought to increase her intake to see if it would help her urinate and it didn't seem to help much. She received a prescription on 26Mar2021, and during that week, she noticed that she was having more issues with some burning during urination and was developing pelvic pain and pressure. The patient stated that the scent and color of her urine looked fine.  She reported that the frequency started to increase with not much urine coming out. When she finished her antibiotics about 7 days later, the urine retention had really improved and went away at the end of March. In the morning of 26Mar2021, when the patient woke up, she had blood in her urine and clots. The clots were about the size of a pea and a couple were about the size of a dime. The blood and blood clots in her urine were what made her go to the doctor. She reported she has never had blood in her urine that she remembers. She was put on Macrobid for 5 days. She reported that Macrobid wasn't relieving enough of her symptoms and her provider ended up adding a couple more days. The patient reported feeling more worn out in Mar2021, since she received the first dose of the COVID-19 vaccine. This did not improve and some days it was worse. The patient did not have the energy level and stamina that she used to (Mar2021). She reported that whether it's combined with the retriggering of her post-concussion syndrome, it is significant for her life. She was also not eating well and had lost some weight (Mar2021). She reported that her appetite is improving but it is still not normal for her. She mentioned it was harder for her to want to eat something because of feeling nauseated. The patient assessed the events "face and ears became very flushed, red, and itchy", headache, "headache was more like a migraine/felt like a migraine, but worse", "post concussion syndrome was retriggered", "blood in her urine and clots", "not eating well and had lost some weight" and "feeling more worn out" as serious (medically significant). The patient recovered from "face and ears became very flushed, red, and itchy" and "she is allergic to alcohol and thought maybe it was the glycol in the COVID-19 vaccine that caused the reaction" on 10Mar2021; headache, "headache was more like a migraine/felt like a migraine, but worse", "she was not able to release the urine (urine retention)", "blood in her urine and clots", "flu like symptoms", dizziness, "achiness all over", "pelvic pain and pressure", and "some burning during urination" in Mar2021; and was recovering from "not eating well and had lost some weight". The outcome of the remaining events was unknown. The patient assessed the causality of events headache, flu like symptoms, nausea, "face and ears became very flushed, red, and itchy", dizziness, "post concussion syndrome was retriggered", and "not eating well and had lost some weight" as related to BNT162B2.; Sender's Comments: Based on the information in the case report and a plausible temporal association, A possible causal relationship between urinary retention, hemorrhage urinary tract and suspect drug BNT162B2 cannot be excluded.
