I have been recently diagnosed with Essential Thrombocythemia. My platelet count before the Moderna Covid vaccine was always around 205. I had a severe reaction to the vaccine for 4 weeks afterwards, with symptoms that include fever, increased heart rate, low energy, hives, and unable to sleep. One year after the vaccine, my platelets rose to 349. Now my platelets are 467. I recently had a bone marrow biopsy and was diagnosed with ET due to a CALR bone marrow mutation. I do have an underlying condition of Sjogrens. Could there be a link between the covid vaccine I had, and Essential Thrombocythemia??
