An 80-year-old male patient received BNT162b2 (BNT162B2), on 20Apr2021 as dose 1, single (Batch/Lot number: unknown) and on 10May2021 as dose 2, single (Batch/Lot number: unknown) for COVID-19 immunisation. The patient's relevant medical history included: "diabetes" (unspecified if ongoing); "asthma" (unspecified if ongoing). The patient's concomitant medications were not reported. The following information was reported: DRUG INEFFECTIVE (hospitalization, medically significant, life threatening), COVID-19 (hospitalization, medically significant, life threatening), ACUTE RESPIRATORY DISTRESS SYNDROME (hospitalization, life threatening), RESPIRATORY FAILURE (hospitalization, life threatening) all with onset 13May2021, outcome "recovered" (2021) and all described as "On 13May, malaise, myalgia, and diarrhea developed/On 19May, SARS-CoV-2 PCR test was positive/severe COVID-19, ARDS, and respiratory failure". The patient was hospitalized for drug ineffective, covid-19, acute respiratory distress syndrome, respiratory failure (start date: 20May2021, discharge date: 02Jun2021, hospitalization duration: 14 days). The patient underwent the following laboratory tests and procedures: Blood test: (27May2021) Unknown results; Gene sequencing: (unspecified date) 30; (unspecified date) 31; (unspecified date) 31; Nasal Swab: (21May2021) Unknown results; SARS-CoV-2 test: (19May2021) positive. Therapeutic measures were taken as a result of drug ineffective, covid-19, acute respiratory distress syndrome, respiratory failure. Additional information: Individual 1 is an 80-year-old man with diabetes and asthma who received the BNT162b2/Pfizer vaccine on 20 April and 10 May 2021.
