From my Hemotologist due to thick blood already due to high RBCs and Hemo numbers. They are writing me an exemption, but it will do me no good anyway as they aren't accepting exemptions apparently. So they are going through the BC items for exemptions and hopefully ill have one this week. If i need a vacc, i will take the nova vax POSSIBLY, but up to now, no desire to take a vaccine for covid that comes with clotting issues that i am in danger of occurring. I get phlebotomies every month and still am out of range, even when off roids for two years, I've had it since a wee lad, as does my father.
