Clinical narrative: Life-threatening cardiac tamponade following COVID-19 vaccination; 3 recurrences of pericarditis/One was within 48 hours of his COVID-19 booster; Pericardial effusion; This is a literature report for the following literature source(s):   A 75-year-old male patient received BNT162b2, BNT162b2 omi ba.4-5 (BNT162B2, BNT162B2 OMI BA.4-5), as dose 3 (booster), single (Batch/Lot number: unknown) for covid-19 immunisation. The patient's relevant medical history included: "rheumatoid arthritis" (ongoing); "Pericardiocentesis" (unspecified if ongoing), notes: removed 275 ml of exudative effusion with 14,140 nucleated cells/mL; "cardiac tamponade" (ongoing). The patient's concomitant medications were not reported. Vaccination history included: Bnt162b2 (DOSE 1, SINGLE), for COVID-19 immunisation; Covid-19 vaccine (DOSE 2, SINGLE (UNKNOWN MANUFACTURER)), for covid-19 immunisation. The following information was reported: CARDIAC TAMPONADE (hospitalization, medically significant, life threatening), outcome "unknown", described as "Life-threatening cardiac tamponade following COVID-19 vaccination"; PERICARDITIS (hospitalization, medically significant), 48 hrs after the suspect product(s) administration, outcome "unknown", described as "3 recurrences of pericarditis/One was within 48 hours of his COVID-19 booster"; PERICARDIAL EFFUSION (hospitalization, medically significant), outcome "unknown". The patient underwent the following laboratory tests and procedures: Bacterial test: negative; Cytology: was inconsistent with malignancy; Cytomegalovirus test: no; Epstein-Barr virus test: no; Fungal test: negative; Nasopharyngeal swab: negative, notes: for SARS-CoV-2; SARS-CoV-2 test: negative. Therapeutic measures were taken as a result of cardiac tamponade, pericarditis, pericardial effusion.  Background: The author present two cases of life-threatening cardiac tamponade following COVID-19 vaccination. Methods: Two cases of cardiac tamponade in temporal association with COVID-19 vaccination were reviewed. Case 1: was 75-year-old male with rheumatoid arthritis admit with chest pressure and hypotension 2 days after his 1st dose of Pfizer-Biontech COVID-19 vaccine. Pericardiocentesis removed 275ml of exudative effusion with 14,140 nucleated cells/ml. Fluid bacterial and fungal cultured were negative; cytology was inconsistent with malignancy. He had no Epstein-Barr Virus (EBV) or cytomegalovirus (CMV) viremia. Symptoms resolved on prednisone and colchicine. A week later, he had an uneventful second COVID-19 vaccine. He went on to have 3 recurrences of pericarditis starting two months after his first. One within 48 hrs of his COVID-19 booster. He was on long term prednisone. Conclusion: Given the proximity to COVID-19 vaccination and lack of alternative explanations, the author believe that tamponade was a direct result of post-vaccine inflammatory pericarditis. Neither patient had a prior history of pericardial effusion. Both tested negative for SARS-CoV-2 by nasopharyngeal swab excluding active infection. Healthcare providers should consider the possibility of pericardial effusion and tamponade in patients with chest pain, shortness of breath, or hypotension following COVID-19 vaccination.; Sender's Comments: There is a reasonable possibility that the event pericarditis was related to BNT162b2, BNT162B2 OMI BA.4-5 based on known drug safety profile and close temporal relationship. Based on the temporal relationship, the association between the events cardiac tamponade and pericardial effusion with BNT162b2, BNT162B2 OMI BA.4-5 can not be fully excluded.
