Free text: I have Chronic myelogenous leukemia (CML). I have been taking Bosutinib 150mg and my platelets have been low, fluctuating between lower 30s to 60s. On Jan 20, I took the Moderna vaccine. Two days later, on 1/22/2021, the platelets dropped to 11. There was no bleeding symptoms. Nevertheless the doctor asked me to infuse a bag of platelets today. I dont know if my thrombocytopenia is related to vaccination?

Each entry is dated by the survey it was written in (the CDC re-sent the releases with survey dates in 2025); click a date to see that survey response. The CDC cut some text off at about 250 characters: symptoms in every release, and the other two fields in releases 9-12. Those entries are marked "cut off by CDC".
