V primeru, da pokličete Ameriško zvezo pediatrov in jih vprašate, kolikšna je količna derivatov živega srebra, aluminija in formaldehida, ki jo je še varno injicirati v dojenčka, lahko posumijo na zlorabo otroka. Potem, ko se pomirijo, vam bodo pojasnili, da varna količna ne obstaja, saj so to vse potencialno karcinogene snovi. Toda derivati živega srebra, aluminij in formaldehid so sestavni elementi večine cepiv. Kako je mogoče, da so le ta varna? Odgovor je odvisen od tega, kdo jih injicira. Če vi ali jaz v svojega otroka vbrizgamo živo srebro ali formaldehid, nas bodo zaprli. Toda, če farmacevtska družba in zdravnik vbrizgata enake kemikalije, potem so popolnoma varne.

 
If you call the American Association of Pediatrics and ask them what is the safe dosage of mercury derivatives, aluminum and formaldehyde to be injected into an infant, they may suspect child abuse. After they have calmed down, they will explain that there is no safe dosage because these are all potentially carcinogenic substances. But mercury derivatives, aluminum and formaldehyde are ingredients in most vaccines. How is it possible that they're safe? The answers depends on who is injecting them. If you or I inject our child with mercury or formaldehyde we are going to jail. But if a drug company and a doctor inject the same chemicals then they are perfectly safe.
