08/24/2023 Dr. Peter A. McCullough: The reason that we are seeing primarily heart problems from Covid vaccine is that the heart can’t tolerate much inflammation while many other organs can tolerate some inflammation. A paper by Avolio showed the support cells in the heart take up the mRNA more avidly than others and then translate the mRNA. The spike protein is expressed on the cell surface of these parasites, causing the body’s immune system to attack the heart.
