This article does not address the concentration of vaccine residue in whatever “shedding” occurs. If you take an aspirin your blood concentration of salicylic acid goes up, because it is the main ingredient in aspirin. After you excrete it, it goes into the sewer and from their into a river, etc. The same is true of antibiotics, Xanax, any medicine you take. However the concentration of these medicines in the water you drink is probably 1 million times lower than it was in your blood. If you gave someone a Covid vaccine with a concentration of MRNA 1 million times lower than a full dose, I don’t think it would have much of an effect. Stop the bedwetting, Alex Jones.
