Vaccines are tested one at a time and no consideration is given to the fact that they are injected simultaneously. They are also not tested with a genuine placebo (i.e. water or a sugar pill) – instead another vaccine is used as a placebo, or a noxious substance like aluminium that is capable of causing multiple side-effects.
Completely unvaccinated children are never used as a comparison because medical authorities say it would be ‘unethical’ to withhold vaccines from them. This is despite the fact that there are thousands of unvaccinated children around including my own who would be more than willing to be a comparison. Because they will not have a genuine study of the health of vaccinated and totally unvaccinated children.
When the term ‘unvaccinated’ is used in studies it refers to one specific vaccine, for instance, the child is unvaccinated for MMR (but had DTaP/IPV/Hib etc), or it can refer to people who were previously vaccinated who no longer show any antibodies. Study researchers will even exclude children from their study results or refer to them as ‘unvaccinated’ if they get the disease they were vaccinated for within two weeks of the shot or if they die.

There have been a couple of studies looking at risk factors for allergy that weren’t specifically about vaccines that looked at the health of Steiner children (a large proportion of whom are unvaccinated and use alternative medicine) and they found that they have less allergies and fewer doctor visits.
Another problem is that when researchers test whether a new vaccine causes any more disease than in the normal population they don’t test disease rates against unvaccinated children, they test them against the general population. Since the vast majority of the public are vaccinated, they are essentially testing the study group against itself. If the rest of the population are neurologically damaged, it’s not going to seem as if the test vaccines cause a spike in neurological illnesses.
