short of breath; first three to four minutes it was very hot and sweaty; my arm from the shot all the way down to the bottom of the muscle of my arm it was red around my whole arm; I have COPD and emphysema and I was getting flare ups for the last three or four days off and on; chest pain off and on; I have COPD and emphysema and I was getting flare ups for the last three or four days off and on; This is a spontaneous report received from a contactable reporter(s) (Consumer or other non HCP). The reporter is the patient.  A patient (no qualifiers provided) received BNT162b2 (BNT162B2), on 19Jul2022 as dose number unknown (booster), single (Batch/Lot number: unknown) for covid-19 immunisation; coviD-19 vaccine mrna (mrna 1273) (MODERNA COVID-19 VACCINE), as dose number unknown (booster), single (Batch/Lot number: unknown), as dose number unknown, single (Batch/Lot number: unknown) and as dose number unknown, single (Batch/Lot number: unknown) for covid-19 immunisation. The patient's relevant medical history and concomitant medications were not reported. The following information was reported: DYSPNOEA (non-serious), outcome "unknown", described as "short of breath"; HYPERHIDROSIS (non-serious), outcome "unknown", described as "first three to four minutes it was very hot and sweaty"; ERYTHEMA (non-serious), outcome "unknown", described as "my arm from the shot all the way down to the bottom of the muscle of my arm it was red around my whole arm"; EMPHYSEMA (non-serious), CHRONIC OBSTRUCTIVE PULMONARY DISEASE (non-serious), outcome "unknown" and all described as "I have COPD and emphysema and I was getting flare ups for the last three or four days off and on"; CHEST PAIN (non-serious), outcome "unknown", described as "chest pain off and on".  Additional information: Consumer stated, "I got the Moderna Vaccine and then I got the Moderna Vaccine (Further not clarified hence captured as Unspecified Vaccine) then I got the Moderna booster Vaccine and here this Tuesday I got the Pfizer booster Vaccine (Further clarifications unknown hence event captured as per verbatim; I got the Moderna Vaccine; this Tuesday I got the Pfizer booster Vaccine) due to that the Moderna was out and I have had some serious side effect on this Pfizer vaccine (Later clarified as Pfizer COVID-19 Vaccine) I just have a couple of question about it." Consumer stated, "I am just concerned about some of the side effect that I have been receiving on this Pfizer Vaccine." When probed for the medical query: Consumer stated, "Well when I got the shot I was very short of breath for like the first three to four minutes it was very hot and sweaty but it all went away that was after getting the shot. The next morning when I woke up my arm from the shot all the way down to the bottom of the muscle of my arm it was red around my whole arm. I have COPD and emphysema and I was getting flare ups for the last three or four days off and on (Event captured as per verbatim) and along with that I have been getting chest pain off and on. Why is this medicine reacting that way because when I got the Moderna they do not gave me any kind of reactions.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.
