New Quality-Control Investigations on Vaccines: Micro- and Nanocontamination
SYNOPSIS
Italian scientists find unexpected contaminants in all pediatric vaccines, including lead, stainless steel, tungsten, iron, and chromium

SUMMARY
Scientists found contaminants in all vaccines that are not listed on the label of the vaccines. “The analyses carried out show that in all samples checked vaccines contain non biocompatible and bio-persistent foreign bodies which are not declared by the Producers, against which the body reacts in any case. This new investigation represents a new quality control that can be adopted to assess the safety of a vaccine. Our hypothesis is that this contamination is unintentional, since it is probably due to polluted components or procedures of industrial processes (e.g. filtrations) used to produce vaccines, not investigated and not detected by the Producers. If our hypothesis is actually the case, a close inspection of the working places and the full knowledge of the whole procedure of vaccine preparation would probably allow to eliminate the problem.”
Interindividual variations in the efficacy and toxicity of vaccines
SYNOPSIS
Researchers warn of sizable difference in individual reaction to vaccines, stress need to avoid increasing side effects of vaccines.

SUMMARY
“A number of currently available vaccines have shown significant differences in the magnitude of immune responses and toxicity in individuals undergoing vaccination. A number of factors may be involved in the variations in immune responses, which include age, gender, race, amount and quality of the antigen, the dose administered and to some extent the route of administration, and genetics of immune system. Hence, it becomes imperative that researchers have tools such as genomics and proteomics at their disposal to predict which set of population is more likely to be non-responsive or develop toxicity to vaccines.. With the increasing number of side effects associated with a number of vaccines reported over the years, it has become imperative to develop new technologies that can effectively assist in the development and evaluation of vaccines for efficacy and toxicity.”
