Vaccination history included: BNT162b2 (DOSE 1, SINGLE, Lot:EN6206), administration date: 10Mar2021, for COVID-19 immunisation. The following information was reported: THROAT TIGHTNESS (non-serious), outcome "unknown", described as "throat closing sensation"; CHILLS (non-serious), outcome "unknown", described as "Chills, shivering"; FLUSHING (non-serious), outcome "unknown". Additional information: First dose Covid-19 vaccine, Pfizer: 10Mar2021 LOT: EN6206 Second Dose Pfizer: 31Mar2021 LOT: ER8733, would have been left shoulder, upper arm for all Covid vaccines. Always gets vaccines in left arm, other than 1 time, got Covid in left arm, flu shot in right arm. After first dose had mild reaction, after second dose, did not need Epi pen. Was having throat closing sensation. Chills, shivering, flushing were all way more intense, than before allergic Sulfa drug class antibiotics. Had reaction to 1 type sulfa, was mild anaphylaxis, years ago. CT contrast for CAT scans, specifically, 60 percent intravenous radio contrast dye. Had mild reaction, throat closing, rapid heart beat, feeling faint, nausea, hives. Has to be pre medicated in future, if needing contrast. Cephalexin, less specific of allergy, said to avoid, seemed to exacerbate colorectal bleeding, best to avoid for safety. More of intolerance, than allergy. Dilaudid is brand name, generic medication is Hydromorphone, which causes serotonin syndrome response. Fainted, had full body tremors, severe with nausea. Was told to avoid narcotics. Does not know if more allergy than seratonic drug sensitivity. Causes heart rate and breathing problems, muscle spasms, high likelihood of reaction with SSRIS, MAOIS, SSNRIS Benadryl. Would start having rapid coughing, asthma attacks, chest pain, feeling super faint. Acetaminophen, found when reaction with Theraflu formula, powder thing, put with hot water. Had not reaction to any other ingredients separately, other than Acetaminophen. Told by doctor, to avoid Acetaminophen, would have mild anaphylaxis, hives, rash itching dizziness. Has dairy and kiwi allergy. Mild allergy to Latex, not always but, sometimes, gets rash from adhesive pastes, like the pastes used in EEGs, when having sleep study. That pastes causes hives, swelling, redness itching. Allergic to chemicals like Oxybenzone, chemicals in sunscreen.
