<“What is common to the two COVID-19 vaccines recently observed to be associated with thrombotic thrombocytopenia (TT) are that they both use adenovirus as vectors”>
However, consider this excerpt from a Jan. 12 NYT report on the case of a Florida doctor who had taken the Pfizer mRNA vaccine:
“Dr. Gregory Michael, a 56-year-old obstetrician and gynecologist in Miami Beach, received the vaccine at Mount Sinai Medical Center on Dec. 18 and died 16 days later from a brain hemorrhage, his wife, Heidi Neckelmann, wrote in a Facebook post.
Shortly after receiving the vaccine, Dr. Michael developed an extremely serious form of a condition known as acute immune thrombocytopenia, which prevented his blood from clotting properly.”
The case of the doctor may have been very different, as it involved bleeding rather than blood clots. However, platelet problems were involved here, too.
thrombotic thrombocytopenia causes BOTH abnormal clotting AND bleeding:
