2 weeks ago I thought I was dealing with coof symptoms because I wasn't well and had shortness of breath. Update: just got out of the hospital having been treated for pulmonary emboli and a blood clot in my kidney. Just before I became ill two of my coworkers got boosters both were sent home feeling sick. Two days later I got sick. I wasn't tested so I don't have a positive result. Just the clots. Has anyone come across any evidence of a booster causing a shedding event like this?
