Other Case identifier(s): D-1-GN-25-009967 . A female patient received BNT162b2 omicron (lp.8.1) (COMIRNATY (2025-2026 FORMULA)), in 2025 as dose 1, single (Batch/Lot number: unknown) for covid-19 immunisation. The patient's relevant medical history included: "non-smoker/did not smoke" (unspecified if ongoing). The patient's concomitant medications were not reported. The following information was reported: MYOCARDITIS (medically significant) with onset 2025, outcome "unknown"; POOR PERIPHERAL CIRCULATION (non-serious) with onset 2025, outcome "unknown", described as "affected circulation in her legs/poor circulation in her legs"; BLOOD VISCOSITY ABNORMAL (non-serious) with onset 2025, outcome "unknown", described as "changes of blood viscosity"; PERIPHERAL SWELLING (non-serious) with onset 2025, outcome "unknown", described as "extreme swelling in her legs and feet"; HYPOAESTHESIA (non-serious) with onset 2025, outcome "unknown", described as "numbness throughout her whole body including in her hands, legs, arms"; RESTLESS LEGS SYNDROME (non-serious) with onset 2025, outcome "unknown", described as "restless leg syndrome"; DYSPNOEA EXERTIONAL (non-serious) with onset 2025, outcome "unknown", described as "severe shortness of breath whenever she was walking"; VEIN DISORDER (non-serious) with onset 2025, outcome "unknown", described as "severely affected her veins throughout her body"; CARDIAC DISORDER (non-serious) with onset 2025, outcome "unknown", described as "weird feels in and around her heart area". The events "extreme swelling in her legs and feet" and "affected circulation in her legs/poor circulation in her legs" required emergency room visit. Clinical information: She was filing this civil lawsuit because of the negative severe side effects she had experienced from receiving the Pfizer COVID-19 Vaccine. Since receiving that vaccine she had experienced severe shortness of breath whenever she was walking, she had experienced extreme swelling in her legs and feet, she had also experienced restless leg syndrome, the vaccine seems to have affected her overall circulation in her legs and she has experienced weird feels in and around her heart area. None of these things was happening to her until she received the Pfizer COVID-19 vaccine. She was able to walk long periods of time without having shortness of breath. She did not smoke, or do drugs, and hardly drinks and so she knew these things she was experiencing was tied to the vaccine because she was not in poor health. After the shot her overall body side effects have been horrible. She had to go to the emergency room because of the severe swelling she had in her legs because of the poor circulation in her legs. She believed that not only did the vaccine affect her legs and her heart, but it severely affected her veins throughout her body. She believed the poor circulation was because of the changes of blood viscosity she had experienced after getting the COVID-19 vaccine. She also experiences weird sensations in her heart area. She had also experienced numbness throughout her whole body including in her hands, legs, arms, etc. and she believed that was tied to the changes in blood flow through her vein which was tied to the poor circulation, numbness, restless legs syndrome, and possibly the weird sensations she was experiencing in her heart region of the body. She believed the Defendant falsely advertised their vaccine as being good and effective, but she believed the way the Defendants advertised their vaccine was a lie and the company downplayed the side effects of their vaccine. She believed she might be one of those people who developed Myocarditis from Pfizer's COVID-19 vaccine. She believed that company was negligent in misrepresenting the effectiveness of their vaccine and downplaying the side effects.
