A 76-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE), dose 1 via an unspecified route of administration, administered in Right Arm on 02Mar2021 14:26 (Batch/Lot Number: EN619G) as single dose for vaccination. Medical history included joint replacements (specified as 1 hip done in 2007; right knee done in Jan2013; another knee was done in Feb2017; another knee was done in 1986); and in 2011, neck fracture. There were no concomitant medications. The patient had the 1st dose of the PFIZER-BIONTECH COVID-19 VACCINE and on 02Mar2021, she had sore on the injection site, experienced excess saliva production. On 05Mar2021, she experienced chills, feeling of heart attack: left arm pain, jaw pain, facial pain. She is worried to take the 2nd shot as she might have more symptoms on the 2nd dose. On an unspecified date, the patient had lower back, hips, knees, neck pain, eye socket hurts when rolling her eyes, sore stomach, and exhausted. It was also reported as follows: on 02Mar2021 after she got home from being administered the Pfizer-BioNTech COVID-19 Vaccine she had quite a bit of saliva in her mouth, it filled up quite a lot; and a bit of a sore arm for a couple of days but that was about it at that point. On Friday, 05Mar2021 she started getting chills and aches; and felt like she was having a heart attack: her left arm hurt and her left side of face hurt down in her jaw. She was afraid and considered going to the hospital but thought she was going to wait it out see what it is and it passed. She then once again got a lot of saliva in her mouth again. Over the next few days she developed aches that were primarily located in her joint replacements, it seemed like the aches attacked those areas of joint replacements in her hips, knees and where she had a neck fracture. She had a lot of pain and a lot of chills. She was never bedridden, but would lay down because she was exhausted. Her back hurt a tremendous amount. Another thing that happened is her eyes, when she would go to move her eyes left or right or up or down it seemed like her eye sockets just hurt to move her eyes; she did not have a headache; this whole indentation there with her eyes hurt to move them from one side to another. She also had a very sore, uncomfortable stomach; it was not an upset stomach; just seemed very sore, uncomfortable. At first that first part of 05Mar2021 she seemed a bit congested. She is very worried about second dose of Pfizer-BioNTech COVID-19 Vaccine because of the first dose creating all of these difficulties. She does not know what she should be doing. She is scheduled to get her second dose of the Pfizer-BioNTech COVID-19 Vaccine on 24Mar2021 because she is leaving by plane on 29Mar2021. That only gives her like 4-5 days before she leaves and she knows that the other symptoms after the first dose of the Pfizer-BioNTech COVID-19 Vaccine did not start until 3 days later. She is concerned about that, because she is flying to take care of her sister; she is worried about the second dose because she does not like what she experienced with the first dose because she heard that the second dose will be terrible; she is worried about leaving and experiencing those horrible things. She reported that there are no tests/investigations relative to this report to provide. The only thing recently done was having X-rays of her neck on 24Feb2021 because of her neck issues with the fractured neck she had in 2011. Outcome of the events was unknown.
