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.
