The blood clotting issue is also a huge concern for me.
While my mother was pregnant with me, she suffered a Deep Vein Thrombosis in her leg, and the both of us almost died.
Her mother also had clotting issues, along with a few others in my family. For several weeks after I underwent a complete Hysterectomy, I had to wear compression stockings on my legs and give myself daily shots in my legs, because of my family’s history of clotting.
I don’t see any need for people with family histories like yours or mine to take a risk, just for an experimental vaccine for a virus with an incredibly high survival rate.
