COVID pneumonia in both lungs; positive COVID-19 test with symptoms; This is a spontaneous report received from a contactable consumer (patient) via a Pfizer-Sponsored Program. A 54-year-old female patient received the first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 MRNA VACCINE; solution for injection; Lot Number: EP7534) via an unspecified route of administration on 22Mar2021 at 13:00 (at the age of 54-years-old) as a single dose in the left arm for COVID-19 immunisation. Medical history included asthma, mitral valve prolapse and sulfa allergy, all from unspecified dates and unspecified if ongoing and exposure to COVID-19 prior to the vaccine on 18Mar2021. The patient did not have a history of adverse events that followed prior vaccinations. Concomitant medications (other products) were reported as no. The patient did not receive any other vaccinations within 4 weeks of the COVID-19 vaccine. The patient experienced positive COVID-19 test with symptoms on 24Mar2021 and COVID pneumonia in both lungs on an unspecified date. The course of events was reported as follows: The morning before the vaccine on 22Mar2021 the patient had a COVID-19 test (nasal swab), and it was negative. She had that test because she had exposure prior to the vaccine on Thursday 18Mar2021. On 24Mar2021 she tested positive for COVID-19 via a nasal swab. The patient tested positive twice on 24Mar2021, she went to two different locations to get tested. On Monday 29Mar2021 the patient went to a medical facility and tested positive. When the patient first had symptoms, she thought it was from the vaccine, but she saw that she was getting worse and thought to herself that this was not from the shot. On Friday 02Apr2021, her husband had to take her to an emergency room (ER), because she got to a point where she had trouble getting air in. The patient thought it was due to her asthma. At the emergency room, they did a CT scan and chest X-ray, and said she had COVID pneumonia in both lungs (also reported that the pneumonia was diagnosed on 29Mar2021). The patient was not admitted to the hospital. The ER staff told her that if she maintained her oxygen level in the 90s, she was good to be at home. When the patient would walk, it would drop, but when she would sit back down the level would come back up. As long as she could keep her level in the 90s, she did not need oxygen. The patient also had 2 inhalers and she was still on both of them at the time of this report. She was on an emergency inhaler prior to the ER visit and they prescribed her 1 new inhaler. They also put her on singular morning and night. She had an albuterol sulfate HFA inhaler that was prescribed to be used every 6 hours. The new inhaler that they prescribed in the ER was levalbuterol tartrate HFA every 6 hours. New medications from the ER included: singular and levalbuterol tartrate HFA. The patient also saw a pulmonologist and had a follow-up appointment scheduled with him. The patient thought that since she had asthma, it prolonged her being sick. The patient called regarding her second dose of the Pfizer COVID-19 vaccine which she was scheduled for "today". She had spoken to her doctor but she wanted to confirm whether it was okay for her to get the second shot "today". The patient stated that she developed COVID pneumonia and had since recovered. She stated that "yesterday" would have been six weeks since she received the first dose of the vaccine and she wanted to know if it was okay to proceed with getting the second dose today. The patient thought six weeks was a good gap. She also asked whether she needed to get another negative test before she could get her second dose. The adverse events required a visit to the emergency room and to a physician office (pulmonologist and primary care). The clinical outcomes of the events COVID pneumonia in both lungs and positive COVID-19 test with symptoms were both recovered/resolved on an unspecified date.
