Clinical narrative: coughing; hyperventilating; could not get her O2 sats up; felt like someone was sitting on her chest; felt really weak and tired; felt really weak and tired; This is a spontaneous report from a contactable consumer (patient). A 53-years-old female patient received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Formulation: Solution for injection, Batch/Lot Number: EN6207), via an unspecified route of administration, administered in arm left on 12Mar2021 (at the age of 53-years-old) as dose 1, single for COVID-19 immunisation. Medical history included eosinophilic asthma. Concomitant medication(s) included salbutamol (ALBUTEROL HFA), ipratropium bromide, salbutamol sulfate (DUONEB) and prednisone, all taken for asthma. The patient called because she had an interesting experience. She has a complicated medical history, she was diagnosed with high eosinophilic asthma, and takes on and off prednisone and going to see a specialist and possibly starting a new medication soon. She got the first Pfizer COVID vaccine on 12Mar2021, stated immediately after she was fine, later that night she felt really weak and tired and so she did fine the next day Saturday (13Mar2021) but was still weak and tired. It resolved by Sunday (14Mar2021). On 14Mar2021, it was hell, she was off of prednisone at the time, her asthma was acting up at the time, stated she takes albuterol and DuoNeb nebulizers as needed. On 14Mar2021, she was coughing all night, it was a different weird coughing not the same as her asthma, sounded shallow, felt like she was hyperventilating. She could not get her O2 sats up, that they were sitting around 90%, felt like someone was sitting on her chest which was not normal for her. The patient stated that the albuterol was not doing anything for her, clarified that it did help a little. The DuoNeb worked, her O2 sats went up to 94, but it was an awful night. On Monday (15Mar2021), she thought she needed to get on prednisone, took 20mg of prednisone and stated at that point she was unsure if it was her disease or the vaccine. She called doctor on 15Mar2021 for a new prednisone prescription and was unable to pick it up because the pharmacy closed, that night she had bad night. She took prednisone on Tuesday, the next morning, took 20 mg in the morning and 10mg that evening, stated that 30 will usually knock out her asthma but she had another bad night. She was really smart that she did some reading, read that prednisone could help people that have an over active immune system or it can weaken the immune system. She further reported that the previous night, she only took 10 mg of prednisone and had a great night. She has only taken 10 mg on 18Mar2021. She was doing really well on 18Mar2021. The patient asked whether she should get the second vaccine - scared to death if that was a reaction to the vaccine, secondly, was there any way to see how much immunity she has with just one shot like a test or something, to see if maybe she had COVID before. The outcome of the events felt really weak and tired was resolved on 14Mar2021 and was resolving for the rest of the events.
