But metallic Mercury is perfectly safe when injected into small children in vaccines, and only a tinfoil hatted lunatic would claim otherwise.
Explanation: as science shows, vaccines are indeed very safe. But the vaccines tested in the lab are not those delivered to the people. The former are just vaccines; the latter have been adulterated with various chemicals to prolong their shelf life. And those chemicals have not even been tested, let alone proven safe.
Thiomersal has been removed from children’s vaccines, JFTR. It’s still present in most adult influenza vaccines, though. It’s not metallic mercury any more than table salt is metallic sodium and gaseous chlorine, but at higher doses it is very toxic, metabolizing to ethyl mercury.
