it showed a "CRP value" of 11.5 which is usually below 0.29 which shows inflammation; loss of appetite; Nausea; breathing problems; mild fever; Muscle ache; Joint ache; Rapid heart rate up to 130; Itchy skin; roof of mouth itching; eyes were also really sore; This is a spontaneous report from a contactable Other HCP (patient).  A 75-years-old female patient received the second dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Batch/lot number: EN6201), via an unspecified route of administration in the right arm on 11Feb2021 at single dose for COVID-19 immunisation. Medical history included ongoing asthma initially diagnosed at 21 years old, ongoing arthritis diagnosed 10-15 years before but she thinks she had it since she was 35, multiple joint replacements, past pneumonia. The patient's concomitant medications were not reported. The patient previously received methotrexate 25mg a week orally for arthritis but she quit taking it about 3 months before in preparation of getting the vaccine. The patient previously received the first dose of bnt162b2 on unspecified date (lot EL8982) at single dose for COVID-19 immunisation in the right arm. The patient experienced mild fever on 12Feb2021 with outcome of recovered on 14Feb2021, roof of mouth itching on 11Feb2021 with outcome of recovered on 11Feb2021, muscle ache on 12Feb2021 with outcome of recovered on 12Feb2021, joint ache on 12Feb2021 with outcome of recovering, breathing problems on 12Feb2021 with outcome of recovering, rapid heart rate up to 130 on 12Feb2021 with outcome of recovering, itchy skin on 11Feb2021 with outcome of recovered on 11Feb2021, it showed a "crp value" of 11.5 which is usually below 0.29 on 15Feb2021 with outcome of unknown, nausea on 12Feb2021 with outcome of recovered on 13Feb2021, loss of appetite on 13Feb2021 with outcome of recovered on 13Feb2021, eyes were also really sore on 11Feb2021 with outcome of recovered on 15Feb2021. An EKG performed on 15Feb2021 as pending results. The event of breathing problems was serious due to disability. The events mild fever, roof of mouth itching, muscle ache, joint ache, rapid heart rate up to 130 and itchy skin were medically significant. The patient reported that initially, the roof of her mouth started itching. It literally happened as soon as she had the vaccine. She took a Benadryl. She didn't have a skin irruption, but did have itchy skin. The next day, she had a low grade fever. She had muscle and joint aches. She had no rash, but a little nausea. She had breathing problems. She had asthma issues and wheezing after the vaccine. That is how she described her breathing issues. She had a rapid heart rate. It went up to 130. It could of been because of fever, her breathing, or pain. There was a period of days then it resolved. On 15Feb2021, she feels almost human. She had routine arthritis lab drawn on 15Feb2021. They showed a CRP level of 11.5 which shows inflammation. She normally was below 0.29 which was within normal limits. That was an extreme difference. That was a lot of inflammation. The patient had to get her nebulizer out to breathe. She has taken Tylenol a couple of times. Her lab work was essentially normal. The CBC and chemical panel was okay. The patient thoughts the fever was important because she has been immunocompromised for years by Methotrexate. She has had pneumonia before with no fevers. Her eyes were also really sore. They bothered her. She already had to use eye drops. That was 11Feb2021 it was gone on 15Feb2021 but it kind of lasted a few days. Her muscles were better, but her joints still hurt some. But her joints always hurt some. She has had multiple joint replacements. The muscles in her legs were severe Friday and Saturday. Her muscles aren't hurting now, but her joints were but that was kind of normal. Her peak flow was way down on 14Feb2021. It was at 250. She did finally get it up to 350 by using her nebulizer. Her best effort normally is 450. Her peak flow was down quite a bit. She has been having breathing changes for a year. They were not sure what it was about. It could be an acute episode of something. On unknown date (next morning as reported), her pulse was 90-100. Now her heart rate was only elevated with activity. Her heart rate was down in the 70s, but when moving it was in the low 100s. With activity it was still up. It was hanging out in the 70s except exercising. She considers walking across the room exercising.  All her other labs were in within normal limits. The patient wanted to know if the inflammatory response was secondary to the vaccine.; Sender's Comments: Based on the current available information and the plausible drug-event temporal association, a possible contributory role of the suspect product BNT162B2 to the development of serious events cannot be excluded.
