" It’s very important the person being vaccinated has healthy kidneys as they are a vital part of eliminating aluminum (Al) from the blood. We wonder if many doctors test infants and children for healthy kidneys before vaccinating them. A good test for this would be to check the Glomerular Filtration Rate (GFR)[105]. This tells us how well the kidneys (glomerulus) are filtering the blood. To know how much aluminum the kidneys can handle, we must know their GFR. "
