For the bradycardia, lightheadedness and foggy brain he had after the 2nd dose of his vaccine, he cannot give the official dates of when those were diagnosed; the bradycardia was ongoing and he has a permanent pacemaker that was placed on 07Jul2021. foggy brain: he would say this is probably about 95 percent cleared. Lightheadedness: it seems to be resolved and resolved on or near the end of Oct2021 or Nov2021. His 2nd dose of vaccine was administered on 24Feb2021 and he could not give a complete expiry date because the month was not on there and it showed the 30th of whatever month in 2021 and the lot looked like EN6201. The Pfizer Covid vaccine 2nd dose was 0.3mL which was what the label said at his hospital in the right upper arm. For his 1st and 2nd doses, it was clarified the facility was specifically (Facility Name withheld) and the vaccine was administered in kind of a conference room setting at the hospital and was not at employee health. After the emergency room visit he saw a neurologist for the symptoms and of course saw a cardiologist due to the pacemaker and his primary care physician and had many of those visits. He missed 9.5 months of work in 2021 and returned to not partial duty but returned for work on 15Sep2021 and worked from 15Sep to April and had to modify and had to change jobs due to still having some of the complications and was not able to physically perform at the same level so had to change the role of his respiratory therapy career. Prior Vaccinations (within 4 weeks): None, had a flu vaccine but it was at the end of Sep2020. Patient's Medical History (including any illness at time of vaccination): None. Family Medical History Relevant to Adverse Events (AEs): None. There is some wear and tear on his patient card and it may be hard to see the labels on there; he received two vaccines and one booster and verified they were all Pfizer; has to get a magnifying glass for the labels and he is not sure if they are facility labels or not but he can read the expiry dates and lot numbers. His health condition worsened and ultimately required an implanted pacemaker due to heart damage. His life changed forever 6 days after the first vaccine. He would like to speak with someone regarding this issue.; Sender's Comments: Linked Report(s) : US-PFIZER INC-202300168790 Same product, patient, different AEs, different dose;
