he got chills as well/He had this side effect with all 3 doses of his Pfizer COVID 19 vaccine; 1st dose: sore left arm; This is a spontaneous report received from contactable reporter(s) (Consumer or other non HCP). The reporter is the patient.  A 54 year-old male patient received bnt162b2 (BNT162B2), administered in arm left, administration date 08Mar2021 (Lot number: EN6200) at the age of 54 years as dose 1, single for covid-19 immunisation. Relevant medical history included: "massive heart attack", start date: 19Feb2014 (unspecified if ongoing), notes: He happened to have a massive heart attack on 19Feb2014 and he has been taking medication since then. The patient took concomitant medications. Vaccination history included: Flu shot (He had his flu shot at (Facility Withheld) in 2020.), administration date: 2020, for immunization. The following information was reported: PAIN IN EXTREMITY (non-serious) with onset 08Mar2021, outcome "unknown", described as "1st dose: sore left arm"; CHILLS (non-serious), outcome "unknown", described as "he got chills as well/He had this side effect with all 3 doses of his Pfizer COVID 19 vaccine".  Additional information: He happened to have a massive heart attack on 19Feb2014 and he has been taking medication since then. He even asked the doctor about that and the doctor said that it could be but he didn't think so because that all happened almost 10 years ago and if the caller was to experience the ringing in his ear from that then it would have happened after 1 to 3 years afterwards, not going into 8 years now, so he doubted that. Caller said that yesterday he was reading on the news about possible side effects of the Pfizer vaccine, he had all three doses including the booster. One of the side effects mentioned on the news was a hearing problem called tinnitus. He remembers that clearly because when he came home that night he was sore on his left side and he told his husband that next time he gets it he is going to ask to have it put in his right arm because he had the sore arm. Within report 2 of 3 caller mentioned that he got chills as well, but it was for just one day. He had missed work for one day and then the next day he was fine and had nothing. He knew that some side effects would be like that. He had this side effect with all 3 doses of his Pfizer COVID 19 vaccine. He also had the sore arm with the 1st dose but he didn't think anything really bad about that. Whenever he gets shots in his arm he knows that he is about to get sore. He thinks he may still have his arm feeling weak. He and his husband also get the flu shot every year and they had that in Nov2021. He didn't want to speculate anything. He had his flu shot at (facility Withheld) in 2020 and then he had his flu shot at (Facility Withheld) in 2021. Caller knew a lot of people have taken the Pfizer shots he just had not asked them about their side effects. He just found out about all this information last night. When he got to work he was going to ask around to see if anyone else has had the same side effect but everyone's body was different. It has been almost a year since he took the 1st dose and for this to start maybe 9 months afterwards he just doesn't know what other side effects might come up. He had no idea, he guesses he will just wait and see if anything else changes or if it continued and got worse. Like he said, it doesn't interrupt any of his duties during the day and the ringing in his ear he only hears for maybe 10 to 15 minutes until his body goes into a deep sleep and it hasn't bothered him with his sleep. He just wanted to report this and see if Pfizer has received any more feedback on this kind of side effect.  No follow-up attempts are possible. No further information is expected.
