The thing is that people need to understand that blood clots form in a number of different ways and for differing reasons. In the same way, coughs are caused by different problems, and the treatment differs too. You don't treat an asthma cough with antibiotics, and you don't treat pneumonia with ventolin. I'm a bit more knowledgeable about blood clots as I have a condition called antiphospholipid antigen syndrome. This makes my blood "sticky". I've had two pulmonary embolisms and multiple DVTs in both an arm as well as in the legs. I take warfarin daily and have done for over twenty years and will do so for life. My INR (degree of blood thinness) is kept very high and I walk the tightrope of risk of severe bleeding on the one hand, and further blood clots on the other. My husband had a massive heart attack over ten years ago and takes Plavix and Cartia to prevent further clots. He can't take my meds, and I can't take his. The method of blood clot formation is different, as is the cascade of events at a cellular level that poses a risk to us both. The clotting problem with this vaccine is different from both what he and I are at risk for. I've had a good discussion with my rheumatologist, a professor at a major Sydney hospital regarding vaccination, and he has told me that, even for me, with such a track record for life threatening clots, I should still have it, because if I did get covid, that would probably be it for me. My husband spoke to his cardiac specialist as well, and was given the same advice.
