Clinical narrative: passed out 2 Wednesdays ago; severe low blood sugars that are untreatable; This is a spontaneous report from a contactable consumer or other non hcp.     A 49-year-old female patient received second dose of bnt162b2 (PFIZER-BIONTECH COVID-19 mRNA  VACCINE, Formulation: Solution for injection, Lot Number: ER8733, Expiration date: Unknown), via an unspecified route of administration, administered in Arm Right on 31Mar2021 13:15-13:30 (at the age of 49-years-old) as DOSE 2, SINGLE for covid-19 immunisation. Medical history included ongoing type 1 diabetes mellitus (She has been a type 1 diabetic for 40 years and does have some mild to moderate complications from diabetes but nothing too serious). The patient's concomitant medications were not reported. Historical vaccine included first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, Formulation: Solution for injection; Expiry Date: unknown, Lot number: EN6208), via an unspecified route of administration, administered in left arm on 10Mar2021 13:00 (at the age of 49-years-old) as single dose for COVID-19 immunisation and experience shingles.The patient experienced passed out 2 wednesday ago on an unspecified date, severe low blood sugars that are untreatable on Apr2021. Caller stated this made her think twice about getting the second dose but she took it anyway because she did not want to get COVID. Shortly after the second shot, strange issues with her blood sugars that have progressively gotten worse. She had severe low blood sugars that are untreatable and that take 3-5 hours to able stabilize even with taking in sugars and candies. The shot  seem to lowered her insulin level and everything a person can do to level it out did not seem to help. It is just bizarre. She did not know if she should thank us or not but it does worry her that the low blood sugar did not respond to sugar for treatment like normal. She was also having issues with the recommendation that the immunocompromised should take a third shot and she was not sure if she could handle her blood sugars going any lower. The caller remarks that her primary doctor told not to take the vaccine and since she decided to, he did  not helping her with the problems afterward. Her main question was, she wants to know if we were aware of this happening with type 1 and what to do. She knows it was out there as she has read blogs about this for other type 1 diabetics having this issue. The caller confirms she has no specific patient details for the statement regarding other type 1 diabetics who have had this issue, she was reading blogs under an article. She can provide the web address if requested. she noticed this about a week after the second dose; she saw some strange roller coaster high to low numbers that were different than her normal. The low blood sugars started in mid Apr2021 and has progressively gotten worse and way more symptomatic to where had stopped responding to treatments. She passed out 2 Wednesdays ago, she did not know the date but luckily her parents were at her home and gave her IM glucagon so therefore she did not have to go to the emergency room. There have been multiple times when she was close to passing out and her husband has had to put sugar under her tongue because she was so out of it. This is the most bizarre thing in her life. She knows type 1 diabetes could not  be reverse and she still sometimes has high sugars when she has had to over treat for hours at a time, so her pancreas was not working but whatever in the vaccine, we might want to look into curing diabetes. She does not know what was in it that is changing the way insulin is synthesized in her system but it would be nice to know how to handle this issue after getting the vaccine. Therapeutic measures were taken with IM glucagon as a result of passed out 2 wednesdays ago. The patient underwent lab tests and procedures which included blood glucose decreased: severe low blood sugars on Apr2021. The outcome of event passed out 2 wednesdays ago was unknown and for event severe low blood sugars that are untreatable outcome was not recovered.  Follow-up attempts are completed.
