Clinical narrative: BNT162b2 mRNA vaccine related pulmonary eosinophilia; This is a literature report.  A 73-year-old male patient received BNT162b2 (BNT162B2), as dose 1, single (Batch/Lot number: unknown) and as dose 2, single (Batch/Lot number: unknown) for covid-19 immunisation. The patient's relevant medical history included: "Non-smoker" (unspecified if ongoing); "nonproductive cough" (unspecified if ongoing); "wheezing" (unspecified if ongoing). The patient's concomitant medications were not reported. The following information was reported: PULMONARY EOSINOPHILIA (hospitalization, medically significant), 1 week after the suspect product(s) administration, outcome "unknown", described as "BNT162b2 mRNA vaccine related pulmonary eosinophilia". The patient underwent the following laboratory tests and procedures: Antibody test: weakly positive, notes: (1:4 titer); Antineutrophil cytoplasmic antibody: Normal; Antinuclear antibody: Normal; Aspergillus test: Negative; Biopsy: revealed organizing pneumonia with mixed, notes: mixed inflammatory infiltrate; Blood creatinine: elevated; Blood immunoglobulin E: normal; Bronchoalveolar lavage: 432, notes: Unit: cells/L revealed elevated WBC with neutrophilic predominance (85%); Computerised tomogram thorax: unremarkable; revealed a 2 cm rounded ground-glass opacity in, notes: the right upper lobe; Eosinophil count: 580, notes: Unit: cells/L eosinophilia at 5%; 6814, notes: marked eosinophilia at 29.5; FEV1/FVC ratio: 76 %; Fibrin D dimer: negative; Forced expiratory volume: 2.80 L, notes: (88% predicted); Forced vital capacity: 3.67 L, notes: 90% PREDICTED; anti-CCP: normal; negative; normal; RES-afebrile and audibly wheezing with a, notes: RES-afebrile and audibly wheezing  prolonged expiratory phase; normal; negative; Oxygen saturation: Unknown resul; 93 %, notes: tachypneic on 4LPM supplemental oxygen; Procalcitonin: negative; negative; Pulmonary function test: normal; Red blood cell sedimentation rate: negative; Respiratory viral panel: negative; White blood cell count: 85 %, notes: revealed elevated WBC with neutrophilic; White blood cell count: 13,200, notes: units as ml leukocytosis; 23100, notes: leukocytosis Unit: /mL. Therapeutic measures were taken as a result of pulmonary eosinophilia.  No follow-up attempts are possible. No further information is expected.; Sender's Comments: As there is limited information in the case provided, the causal association between the reported event: "Pulmonary eosinophilia" and the suspect drug BNT162B2 cannot be excluded. The case will be reassessed once new information is available.
