Inhalation allergic reaction; chemical burns; lips were swelling; This is a spontaneous report from a contactable consumer or other non health professional (Patient's mother).   A 15-years-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, Batch/Lot number was not reported) via an unspecified route of administration on an unspecified date as UNKNOWN, SINGLE DOSE for covid-19 immunisation. The patient's medical history included allergy to Peanuts and other ingredients. Pretty severe allergic reaction to a plant based botanical cleaning product at her school. She had an Inhalation allergic reaction, she was hospitalized after the 3rd trip to the emergency room (ER), then they kept her overnight, because her lips were swelling. The patient's concomitant medications were not reported. It was reported that, many of the ingredients were found in steroids and used as preservatives in antibiotics and stuff. Her daughter was Patch tested. Was severe enough that they said she would have a severe enough reaction - she gets chemical burns. Diazolidinylurea in steroids and used as preservatives in antibiotics and stuff. Imudiazolidinylurea preservative, most steroids creams, and lotions, quinoline mix - never been exposed to it. P phenylenediamine - never had hair dyed. Peanuts, tree nuts, Cherries, Fresh and raw fruits and vegetables, Tree extract, Legumes (certain soy's). Now that she had this severe reaction that has happened about 2 to 3 weeks ago (In May2021). They were concerned about a possible reaction to the vaccine, they wouldn't have even thought about this, had she not had this recent reaction. They did not know what caused the reaction, other than she was allergic to these plants and extracts, it was hard to sit down and figure out which plant caused, it was the Thymol (not sure of spelling) based on our reading. They did not know what caused it, they were spraying the aerosol and her body just couldn't handle it. It was a botanical plant-based product. A review of the ingredients list on the product label show that (allergen/ingredient) was not part of the formulation, however, Pfizer did not specifically manufacture Pfizer BioNTech Covid 19 vaccine to be free of tree nuts, Cherries, Fresh and raw fruits and vegetables, Tree extract, Legumes (certain soy's), Diazolidinylurea, Imudiazolidinylurea, P-phenylenediamine, Quinoline mix therefore, they cannot assure that it was "tree nuts, Cherries, Fresh and raw fruits and vegetables, Tree extract, Legumes (certain soy's)-free," Diazolidinylurea, Imudiazolidinylurea, P-phenylenediamine-free, Quinoline mix-free. They cannot guarantee that minute amounts of substances were not contained in raw materials obtained from our suppliers. To ensure they have a consistent and reliable supply of medications, they must use a network of suppliers and manufacturing sites globally for both active and inactive ingredients. Spoke from attached Animal-Derived Materials: all lipid excipients used in the vaccine were either from plant-derived sources or are synthetic and have no animal components. The outcome of the events was unknown.   Information about batch/lot number has been requested.
