migraine-like headache; This is a spontaneous report received from a contactable reporter(s) (Consumer or other non HCP) from medical information team. The reporter is the parent.  A 7 year-old female patient received bnt162b2 (BNT162B2), administration date 11Nov2021 (Lot number: FK5618) at the age of 7 years as dose 1, single for covid-19 immunisation. Relevant medical history included: "drug allergy to tryptone" (unspecified if ongoing), notes: drug allergy to tryptone (Further clarifications unknown), a little concerned about that. Family history included: "Migraine" (unspecified if ongoing), notes: family history of migraine but daughter was not suffering from migraine prior to getting the vaccine. The patient's concomitant medications were not reported. Vaccination history included: Flu shot (she had the Flu Shot but it was long before and no headache associated with it), for immunisation. The following information was reported: MIGRAINE (non-serious), outcome "not recovered", described as "migraine-like headache". The event "migraine-like headache" was evaluated at the physician office visit. Therapeutic measures were taken as a result of migraine.  Additional information: Consumer reported her daughter experienced a constant migraine-like headache since she received her first dose of the Pfizer-BioNTech COVID-19 vaccine for nearly two months now. Initially patient's pediatrician did not think this adverse event could be related to her vaccination. Patient's pediatrician already ruled out allergies and her dentist any teeth problems. She has been losing hours of sleep at night for 2 months. They took her to a pediatric neurologist, the medicine she was prescribed was not helping, she still experienced this constant headache. Reporter thought it was her six-year molars coming in and never mentioned that it could be the COVID vaccine, it was just her first dose, and she wasn't having any other symptoms at all so that continued and continued. So, they started taking in her into, it seemed a sham like that headache and she was playing around on a couch a lot of the time. She had a high pain, on like she has been a non-biker so she thought bad accident biking so they know for sure she had a high pain, so they took her to a pediatrician who didn't think that it was likely that it was the COVID vaccine but was concerned it might be allergies. They then had her to dentist, the dentist said if her molars were in far enough and didn't think it was the molars was causing it and then we kept seeing the Pediatrician several times in December and referred to Pediatric Neurologist. Reporter stated prior to the COVID Vaccine she had the Flu Shot but it was long before and no headache associated with it. Reporter stated, she had been placed on medication for the headache, they tried Ibuprofen, they initially thought maybe it was allergies that was causing so she was on Flonase, Zyrtec and Benadryl (Treatment) and allergies completely her nose was swollen and tightened and that has completely resolved but the headache remains which is why we were referred to the Pediatric Neurologist and with neurologist."  No follow-up attempts are possible. No further information is expected.
