Therapeutic measures were taken as a result of night sweats, rash, laryngitis allergic, seasonal allergy, dust allergy, allergy to plants, food allergy, sinus congestion, temperature intolerance, serum ferritin decreased, dizziness postural, palpitations, alopecia. Additional information: Initial symptom (starting after second dose): severe night sweats, hair loss. Further symptoms: Night sweats continued for approx 6 months. Stopped, then restarted after the booster in Oct2021. Lasted another 3-6 months and then stopped. New skin rashes - similar to pityriasis rosea. Allergic laryngitis New allergic reactions to pollen, dust, cedar, food groups. Chronic sinus congestion. Heat intolerance, Cold intolerance, Low ferritin not responsive to iron supplementation - reporter stated that this should be investigated as there is a new and increasing population dealing with iron deficiency unresponsive to treatment. Dizziness upon standing, frequent palpitations. These symptoms have been present to varying degrees since Mar2021. They are relapsing and remitting in nature. Prior to being administered the vaccine, patient was a completely healthy with no family history of autoimmune disease. It's almost as though the patient's immune system has been completely rewired.; Sender's Comments: Linked Report(s) : US-PFIZER INC-202300253746 same reporter/patient/drug, different dose/event.;
