really bad headache, excruciating headache; nauseous, nausea/queasy; blurred vision; holes in her vision; not right; like an allergic reaction; She had soreness in the arm; This is a spontaneous report from a contactable consumer (patient). A 63-year-old female patient received the first dose of bnt162b2, via an unspecified route of administration, administered in Arm Left on 05Mar2021 16:32 (Lot Number: EN6198; Expiration Date: 30Jun2021) as single dose for covid-19 immunisation. Medical history included allergies to Sulfa drugs, Penicillin, and believes she has allergies to Ploymers (She cannot wear polyester and she has to wear 100% cotton). The patient's concomitant medications were not reported. The patient (at the age of 62-year-old) previously received the second dose of Shingles Vaccine in Jan2021 for immunization. The patient experienced really bad headache, excruciating headache on 09Mar2021 21:00, nauseous, nausea/queasy on 09Mar2021, she had soreness in the arm on 05Mar2021, blurred vision on 09Mar2021, holes in her vision on 09Mar2021, not right on 09Mar2021, like an allergic reaction on 09Mar2021. She developed a "really bad headache" around 9pm on Tuesday 09Mar2021, that caused holes in her vision and pain "straight across my forehead". She did treat with Tylenol and was able to finally sleep around 5am. She states that the headache has persisted, and she's felt "nauseous, queasy, and not right" since the headache started.  She is hesitant to get the second dose. She was experiencing headache following. She mentioned she is allergic to sulfa drugs, penicillin, and polymers, and thought maybe the headache was a result of an allergy to the vaccine? Ingredients don't appear to have any of her reported allergens. She had soreness in the arm the first 48 hours, which was to be expected and no big deal for her. However, starting on Tuesday, she had an excruciating headache. She normally does not typically get headaches. She believes in vaccinations and as a teacher the minute she could sign up to get one she did. Now she is terrified to get the second one. When this excruciating headache began she woke her husband up to tell what happened. She thought she was going to die, that is how bad it was and she wanted him to be aware and prepared if anything should happen. The excruciating headache started at 9PM. It was excruciating all night. The headache made her queasy because she hurt so bad. It continued into Wednesday. Today and today the pain is duller in her head, much duller than it was. However, she still feels queasy/nauseous. The headache also started with blurred vision. The blurred vision has gone away. It was like there were holes in the TV. She was thinking  it was interesting and did not think much of it at first. She thought one of her contacts had a hole in it, but she did not even have any on. The blurred vision lasted 24 hours. The soreness in arm lasted until Sunday or Monday. She confirmed the pain in arm is gone and was gone by Monday. She initially could not wait to get her shot. Now she is terrified to get the second one. She took Tylenol in the middle of the night on Tuesday and Wednesday for the headache. Has allergies to Sulfa drugs, Penicillin, and believes she has allergies to Ploymers. She cannot wear polyester. She has to wear 100% cotton. She is questioning if the vaccine has polymers in it. From what she heard it does and is wondering if this caused her to have like an allergic reaction. The outcome of the event vaccination site pain was recovered in Mar2021, the events Nauseous and headache was not recovered, other events was unknown.
