difficulty of breathing/shortness of breath; chest tightness/Chest heaviness; arm hurt; Wheezing; pain in her chest; the highest her temperature got was 99.7; This is a spontaneous report from a contactable consumer (patient) via Medical Information Team. A 41-year-old female patient received first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection, Batch/Lot Number: EN6207), dose 1 via an unspecified route of administration, administered in Arm Left on 23Mar2021 at 17:30 (24-hour clock) (Age at Time of Vaccination: 41 years-old) as DOSE 1, SINGLE for COVID-19 immunisation. No medical history and no concomitant medications were reported. Patient had no allergies. The patient had no Family Medical History Relevant to adverse events. Patient had no history of all previous immunization with the Pfizer vaccine considered as suspect, Vaccination Facility Type was other and was not administered at Military Facility. No additional vaccines were administered on same date of the Pfizer Suspect. The patient took no Prior Vaccinations (within 4 weeks). The patient experienced difficulty of breathing/shortness of breath, chest tightness/chest heaviness, arm hurt, wheezing on 24Mar2021 at 18:00 and pain in her chest, the highest her temperature got was 99.7 was on an unspecified date in 2021. Patient stated that she worked Wednesday, Thursday and Friday were just fine, had no type of symptoms the first night, but the second night she had tad of wheezing, only a minute worth, and a little tightness in her chest and shortness of breath on a scale of 1.5/10 but it was to the point she called her doctor. States her doctor said she didn't want to see her and that was normal. States she is calling to see if that is normal and because she has concerns about receiving the second dose, since she had this reaction with the first dose. Clarified her wheezing was only for one minute. Stated her husband said oh great, she was fine until she got the vaccine, she called an allergist and they said they only give Moderna, so they have no idea about the Pfizer vaccine, called the urgent care but they are not giving out vaccines so they did not know and so she figured she would call here to see what type of information she can find out. And now she was still having a little bit of tightness in her chest and shortness of breath, was concerned, but not frightened, just concerned about the second one because she has heard it can be difficult and she loves life and wants it to continue. She was nervous because everyone says the second dose is tougher. Clarified that it did not stop her activities, she still went to work, the highest her temperature got was 99.7, and her arm hurt for a couple of days, has no allergic reactions to anything. She just wanted to check before she takes the next one, she does not want to dump it all on nurse the day of her vaccine, wanted to be proactive rather than reactive. She stated no one knows where she lives. States she knows Pfizer gives no medical advice, but she wanted to know what next step is, maybe its fine. She went and walked for 1.5hours and did okay but feels a little bit of heaviness in her chest that she has never felt before, Stated if this were a one and done type of shot she would figure it will go away, but it was just before her second one and she has a young child, so she was concerned, Stated everyone was so scared where she lives because the numbers are going up and the doctor offices do not want people coming in. States people tell her about the second one, that it brought them down and if she had shortness of breath with the first one and still feels it a bit, she wanted to reach out and she was finding no answers anywhere. States she wants to get the vaccine and be done, but she also wants to be safe. She was on no medication of any kind other than vitamins and she has no health issues and everything was perfect at her last appointment. Patient had her first dose 23Mar the following day she had a very slight shortness of breath for 4 nights, wheezing for a minute and pain in her chest.
