New Quality-Control Investigations on Vaccines: Micro and Nano Contamination


Vaccines  are  being  under  investigation  for  the  possible  side  effects  they  can cause. In order to supply new information, an electron-microscopy investigation method was applied to the study of vaccines, aimed at verifying the presence of solid contaminants by means of an Environmental Scanning Electron Microscope equipped  with  an  X-ray  microprobe.  The  results  of  this  new  investigation  show the presence of micro- and nanosized particulate matter composed of inorganic elements in vaccines’ samples which is not declared among the components and whose unduly presence is, for the time being, inexplicable. A considerable part of  those  particulate  contaminants  have  already  been  verified  in  other  matrices and  reported  in  literature  as  non  biodegradable  and  non  biocompatible.  The evidence  collected  is  suggestive  of  some  hypotheses  correlated  to  diseases  that are mentioned and briefly discussed. …

“Feligen, the only veterinary vaccine tested (out of 44 vaccines), proved to be the only sample free from inorganic contamination…”
