Pfizer adds tromethamine to their Kid’s COVID shots. Thoughts are that they added this drug so the kids will have a delay before the side effects and heart problems kick in. They replaced the saline buffer with this blood thinner. A warning is that the Tris drug should not be injected into muscle because it will destroy the tissue. They are adding additional drugs, usually used intravenously, to an injection for the children. So is Pfizer admitting that the shots aren’t safe?
