Injection site pain; Booster; Arm pain; sick; Tiredness/more tired; Bad headache; Muscle pain; Chills; Joint pain; Fever; Feeling unwell; His lymph nodes under his underarms felt strange; This is a spontaneous report from a contactable consumer or other non hcp (patient).     An 84-years-old male patient received bnt162b2 (COMIRNATY, Solution for injection), dose 3 via an unspecified route of administration on 03Nov2021 (at the age of 84-years-old) (Batch/Lot Number: FF2593) as DOSE 3 (BOOSTER), SINGLE for covid-19 immunization. Medical history was none. Concomitant medication(s) included his regular vitamins. Historical vaccine included bnt162b2 (COMIRNATY, Solution for injection), dose 1 via an unspecified route of administration on 19Feb2021 (at the age of 84-years-old) (Batch/Lot Number: ENG198) and dose 2 via an unspecified route of administration on 12Mar2021 (at the age of 84-years-old) (Batch/Lot Number: ENG206), both as a single dose for covid-19 immunization and experienced sore arm after both doses. Patient had stated that he didn't have any medical information questions he only had called to report that with his first 2 doses of the Pfizer COVID vaccine he only got a sore arm but on the booster dose he mentioned that it made him really sick (on an unspecified adte in Nov2021) and that he had a list of other side effects from it. He confirmed that he has a whole list of things that he had experienced from the booster dose. With the booster dose, on 03Nov2021, he had injection site pain and also had arm pain. On an unknown date in Nov2021, the patient experienced tiredness, a bad headache, muscle pain, chills, joint pain, he had a fever, he was feeling unwell, and he thinks that his lymph nodes under his underarms felt strange and and that was about it. Which he thought was enough. Inquired for when this began and he stated that the sore arm happened almost immediately which it always did and then the next day, unfortunately his wife was in the hospital and he probably shouldn't have got the booster but he didn't experience side effects with the first 2 and he thought oh well, and so he got them and then there was a day where he could not function whatsoever and he couldn't go see his wife in the hospital because of his side effects. Other than that, he seemed to be coming back but his underarm lymph nodes were still having some strange feeling to them but he thought that he was pulling out of it. He got his booster dose on 03Nov2021 and so it had been 6 days since then and he was feeling quite a bit back to normal, but he was not 100% yet, but he thought that he was getting there. Inquired if any of his side effects had completely gone away and he said, oh no all of the others had gone away. He was still tired, more tired than he was normally but the headache was gone, the injection site pain was gone, the muscle pain was pretty much gone, the fever was gone, the joint pain was gone. With the feeling unwell he was feeling quite a bit better. The arm pain was gone. Most of his symptoms were gone but just probably he felt a little bit tired from it all. He was a pretty healthy guy for the most part. He does not take any prescription drugs or anything, he just takes his regular vitamins and he was a pretty healthy guy but this thing set him back for a few days. The outcome of feeling unwell was recovering, tiredness/more tired was not recovered, and all the other events were recovered on an unknown date in Nov2021.  Follow-up attempts are completed. No further information is expected.
