some coughing; headache; congestion; we both had horrible allergies.; This is a spontaneous report received from a contactable reporter(s) (Consumer or other non HCP).  A 24 year-old female patient received bnt162b2 (BNT162B2), administration date Oct2021 (Batch/Lot number: unknown) at the age of 24 years as dose 2, single for covid-19 immunisation. Relevant medical history included: "history high BP" (unspecified if ongoing); "They have randomly broken into hives before" (unspecified if ongoing), notes: unsure when , this was going on but in the last year or two; "and they got allergy tested" (unspecified if ongoing); "environmental Allergy" (unspecified if ongoing); "Bad allergy" (unspecified if ongoing); "potential weight issues" (unspecified if ongoing). The patient took concomitant medications. Vaccination history included: Bnt162b2 (Dose Number: 1 , At least two Pfizer shots - unsure when received but likely by mid-2021.), administration date: 2021, for COVID-19 Immunization. The following information was reported: HYPERSENSITIVITY (non-serious) with onset 06Oct2021, outcome "recovered" (2021), described as "we both had horrible allergies."; COUGH (non-serious), outcome "unknown", described as "some coughing"; HEADACHE (non-serious), outcome "unknown", described as "headache"; NASAL CONGESTION (non-serious), outcome "unknown", described as "congestion". Relevant laboratory tests and procedures are available in the appropriate section. Therapeutic measures were taken as a result of hypersensitivity.  Additional information: All seriousness criteria reported as no. Other medications in two weeks: Likely birth control. Patient already takes allergy medication (nasal) but she had to take more dosage than usual. Reporter believe it was related to mold in the hotel (since would impact both of us in restroom). She already has bad allergies, so it made it worse. Happened a couple other places that were older or in generally dusty as well, but those did not impact me as much. Individual was around 23 or 24 when vaccinated with Pfizer. Reporter believe was vaccinated in the summer. Spent some time with them October 6-12 on vacation. Stayed at a hotel which caused some bad allergies. Definitely gave individual bad congestion, some coughing, and unsure what other symptoms. Individyal also experienced some bad allergies a couple of other places as well. On 08Oct2021 definitely had a lot of issues due to building ate dinner in and later concert venue (so like 06:30 PM onward start). Led to a headache as well as congestion. They took an aerosol nose spray medication for allergies and were already on a larger than normal dose for that - they have bad allergies the doctor prescribes. They considered also benedryl but unsure if they took. They have randomly broken into hives before (unsure when this was going on but in the last year or two), and they got allergy tested but it was inconclusive from what reporter remember them telling. They Reporter believe take birth control and were likely on it at time of vaccination. Reporter unsure what else they take. In terms of medical history there was a period where they may have had higher blood pressure a couple years ago but reporter believe that subsided. They are slightly overweight but Reporter have not heard of other complications. They do get bad allergies which was why they were on that larger dose. Reporter didn't think any of this had to do with the covid vaccine - but it's reported out of caution.Recently got an IUD implanted and there is a separate AE regarding this. Unsure if still on medication originally on at time of vaccination. Reporter not sure of exact vaccination date-but probably fully vaccinated (2 dose) around earlier in the summer. At least two Pfizer shots - unsure when received but likely by mid-2021. Reporter believe this was referring to events in Oct. Reporter think most issues were related to environmental allergies. (Name withheld) has a history of bad allergies and takes medication (nasal spray, Benadryl if necessary) for it. She was taking multiple dosings of the nasal spray at least to accommodate for issue. Reporter believe there was already significant explanation given for this occurrence. (Name withheld) has a history of high blood pressure (however, Reporter think it is a lot more under control than it used to be) and some potential weight issues. Wears glasses/contacts. (Name withheld) has a history of bad environmental allergies - had issue where was breaking into hives sometimes around Sep2020 and was getting allergy tested to figure out what issue was. Results were indeterminate. She told me about this as the issue went on. Since we (Reporter was the other person referenced in this AE but Reporter did not have Pfizer vaccine) are no longer in the environment causing the issue, Reporter believe the issues associated with this have been resolved. If (Name withheld) is having allergy issues, it was likely due to existing issue, as Reporter believe this issue preexists vaccination.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.
