Request

After the COVID injection vaccine spike proteins enters cells modifying them to manufacture more spike proteins. Which cells do they enter? Are there now, or were there ever checks for COVID vaccine particles/spike proteins in donated blood? If not, bearing in mind spike protein production in the vaccinated lasts for years, possibly indefinitely, why not? Please list the viruses, bacteria, spike proteins, nucleotides and all undesirable elements that you test for before allowing blood to be transfused into patients. How do you remove these items to make the blood safe? (Do you have standard procedures, for example filter techniques or absorption?) How about specifically from immune cells and exosomes? How many people have received a transfusion after the vaccination program? Have people who received a transfusion after the vaccination program been tested for spike protein expression? If this is not being actively researched, why not?
