platelet levels are very high, like 700,000 or 630,000.; Massive clotting; Pancreatitis; Splenic infarcts; first dose on Mar2021, second dose on 26Aug2021; This is a spontaneous report from a contactable Consumer (patient). A 66-years-old female patient received bnt162b2 (Pfizer-BioNTech COVID-19 Vaccine), at the age of 66-years-old, dose 2 via an unspecified route of administration, administered in Arm Left on 26Aug2021 (in the morning, exact time unknown) (Batch/Lot number was not reported) as SINGLE for covid-19 immunisation. The patient medical history was not reported. The patient's concomitant medications were not reported. The patient received bnt162b2, dose 1, on Mar2021 for covid-19 immunisation and experienced shingles; headache and neuralgia. The patient experienced massive clotting on Aug2021 with outcome of unknown , pancreatitis on Aug2021 with outcome of recovering , splenic infarcts on Aug2021 with outcome of unknown , platelet levels are very high, like 700,000 or 630,000 on an unspecified date with outcome of unknown. Clinical course as follows: Second dose was administered on what she thinks is 26Aug2021. she thinks she has pretty much recovered completely from the shingles; she just has some residuals of headaches which were initially major headaches that have improved, are just mild on and off headaches; and neuralgia from the shingles which has also improved. she actually tried to go to the hospital for Massive clotting, pancreatitis and splenic infarcts the night of 29Aug2021, but she couldn't get in to the hospital because they were full. She went to urgent care on 30Aug2021 for these events, and was then admitted to the hospital 30Aug2021 until discharged from the hospital the following Tuesday, which would have been 07Sep2021. Regarding outcomes of massive clotting, pancreatitis and splenic infarcts: pancreatitis has gotten better; she is still not, don't know what the word is, she still has discomfort and is still not maintained as far as any blood levels. She is on hold and on rest until they find out what else can be done. They don't have treatment interventions to get her under control with the clotting and scarring and infarcts. She is still under doctor's care. She did speak to the doctor to ask what do they recommend about how to treat this problem; everyone is kind of baffled how to treat it. They're going in different directions; thinking it's the vaccine; wondering does she have cancer now, did the vaccine cause cancer. She wants to know what does she do for intervention while waiting; it's going on a month for her to get in the opposite direction of getting well. She would like to go to another hospital for a full workup but they won't take her without a diagnosis, not with just pancreatitis that has gotten better. Regarding testing/investigations: (Withheld), about a week and a half after she was discharged, did a whole bunch of bloodwork and her platelet levels are very high, like 700,000 or 630,000. They also did a bone marrow biopsy on Friday and a whole lot more bloodwork but she is still waiting on those results. Her platelet levels are very bad and have increased since she was discharged from the hospital.   The lot number for BNT162B2, was not provided and will be requested during follow up.
