Hello there, I was diagnosed with ET in the summer of 2022. My platelet count was over 700 at that time. My hematologist/oncologist put me on 500 HU and a baby aspirin per day. This brought my platelets down to 500. My oncologist then put me on 1000 MG’s of HU and one baby aspirin per day and this brought it down to 420. My husband and I caught Covid. After five days my husband tested negative and did not feel that bad. It took me two weeks to test negative with Covid, and I felt much worse than he did. I am very tired each day and have some dizziness. I did take the Covid vaccine and booster prior to developing ET. I am now reading and looking at some studies on the Covid vaccine. These studies are showing that the vaccine will cause platelets to change. There are many articles about Covid vaccine and platelets if you Google it. Can anyone relate to this Connection between Covid vaccine and change in your platelets. This is so very upsetting.
