she was diagnosed with COVID-19; she was diagnosed with COVID-19; This is a literature report for the following literature source(s). A 52-year-old female patient received BNT162b2 (BNT162B2 NOS), as dose 1, single (Batch/Lot number: unknown), as dose 2, single (Batch/Lot number: unknown) and as dose 3 (booster), single (Batch/Lot number: unknown) for covid-19 immunisation. The patient's relevant medical history and concomitant medications were not reported. The following information was reported: VACCINATION FAILURE (medically significant), COVID-19 (medically significant), outcome "unknown" and all described as "she was diagnosed with COVID-19". The event "she was diagnosed with covid-19" required emergency room visit. The patient underwent the following laboratory tests and procedures: C-reactive protein: normal; EDX testing: revealed evidence of a subacute lumbar plexopathy; sensory loss and absent right patellar reflex; Magnetic resonance imaging spinal: showed mild degenerative changes; showed enlargement and increased signal intensity, notes: of the right proximal L3 and L4 nerves and right femoral nerve, consistent with acute plexitis; Polymerase chain reaction: COVID-19; Red blood cell sedimentation rate: 36, notes: mm/h elevated. Clinical course: A healthy 52-year-old woman presented to the ED with a traumatic, sudden severe low back pain with radiation down the right leg and numbness in the medial anterior thigh and foreleg. Three days prior, she was diagnosed with COVID-19 via nasal swab polymerase chain reaction after mild sinus congestion. She had received 3 doses of the PfizerBioNTech vaccine. Examination revealed sensory loss and absent right patellar reflex. MRI of the lumbar spine showed mild degenerative changes. She presented to neurology 1 month later with persistent pain and sensory loss, as well as weakness in hip flexion, hip abduction, and knee extension. Right patellar reflex was absent. Comprehensive laboratory evaluation revealed an elevated erythrocyte sedimentation rate at 36 mm/h but normal C-reactive protein. No evidence of diabetes, vitamin deficiencies, autoimmune disease, or other infectious diseases. EDX testing revealed evidence of a subacute lumbar plexopathy. MRI of the lumbosacral plexus showed enlargement and increased signal intensity of the right proximal L3 and L4 nerves and right femoral nerve, consistent with acute plexitis. Subsequent treatment included pulse doses of IV solumedrol with improvement of all symptoms.; Sender's Comments: Vaccine efficacy varies from person to person and is affected by many factors. The association between the events vaccination failure, Covid-19 with the suspect product cannot be fully excluded.
