Therapeutic measures were taken as a result of arthritis reactive, lethargy. Clinical course: Patient called about the Pfizer Bivalent. He got the vaccine on 03Nov2022 and had done very well with all Pfizer vaccines. "Is heavily and has been vaccinated beyond that". A week after the Pfizer Bivalent he was very tired and lethargic which turned into arthritis. He has worked through two medical systems to get a solid diagnosis. Patient was waiting for a rheumatology appointment in Sep2023. He lives in the country with their rheumatology. Had a DMAD, a disease modifying anti rheumatic drug. First one was Methotrexate and the second one was Leflunomide. Arthritis reaction he got has been substantial. Did internet reading and a few articles are coming out about mRNA causing arthritis. He wanted to know if Pfizer had a consultant that he could speak with to help gather information about how to deal with this. This has been a life changing event. He had the initial Covid vaccine and booster back in 2021. Later in Oct2021 had the follow up and the year after that in Nov2022 had the Pfizer Bivalent. He did not have problems with other three. Bivalent in Nov2022 hit him much harder than the other three. Clarified that he had Pfizer Bivalent on 03Nov2022.
