Studies comparing vaccinated to unvaccinated populations
Updated, 1/7/2016
According to Barbara Loe Fisher of the National Vaccine Information Center:
1 highly vaccinated child in 45 develops autism in America today;24 1 in 6 has learning disabilities; 25 1 in 9 has asthma;26 1 in 10 has ADHD;27 1 in 12 suffers with depression;28 ,29 1 in 400 become diabetic30 and millions more struggle with other kinds of immune and brain disorders marked by chronic inflammation in the brain and body.31,32, 33, 34

Note: In response to correspondence from a reader, this page was edited on 2/8/2015. Two references to broken links (now showing as “suspended page“) were removed. And, since the sample size of 94 compared to another sample size of over 13,000 cannot provide reliable data, we have removed commentary on the rate of infections and atopy in certain age groups.
Are health outcomes different when one compares vaccinated children with unvaccinated children? To date, there has never been an independent, adequately designed, prospective, randomized placebo-controlled study on this subject containing enough “n” (numbers of children) to have statistical significance.
In fact, this sort of study, that would give the most definitive answer (i.e., long-term total health outcome in the prospective randomized placebo-controlled trial of the whole vaccination schedule) is considered “unethical” by the establishment so only small, biased or “meta-analysis” studies are put in front of consumers. You can find this list of studies at the bottom of this article.
The following is taken in part from Public Testimony of Dr. Heather Rice at the Vermont Department of Health hearing on Act 157, 10/19/2012:
No true prospective, randomized and controlled study of health outcomes of vaccinated people versus unvaccinated has ever been conducted in the U.S. by CDC or any other agency in the 50 years or more of an accelerating schedule of vaccinations.
However, a German study published in 2011 compared the health outcomes of 94 unvaccinated children versus 13,359 vaccinated children (Dtsch Arztebl Int. 2011 February; 108(7): 99–104.”Vaccination Status and Health in Children and Adolescents; Findings of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS).” (pdf of article – reply#1 – reply#2 – reply#3 ). Because the number of unvaccinated children included in the analysis is so small, statistical evaluation is nearly impossible.

Abstract
BACKGROUND:
Whether unvaccinated children and adolescents differ from those vaccinated in terms of health is subject to some discussion.
METHOD:
We evaluated data on diseases that are preventable by vaccination, infectious and atopic diseases, and vaccinations received that had been collected between 2003 and 2006 in a representative sample of 17 641 subjects aged 0 to 17 years in the framework of the German Health Interview and Examination Survey for Children and Adolescents (Kinder- und Jugendgesundheitssurvey, KiGGS).
RESULTS:
Evaluable data on vaccinations were available for 13 453 subjects aged 1-17 years from non-immigrant families. 0.7% of them (95% confidence interval: 0.5%-0.9%) were not vaccinated. The lifetime prevalence of diseases preventable by vaccination was markedly higher in unvaccinated than in vaccinated subjects. Unvaccinated children aged 1-5 years had a median number of 3.3 (2.1-4.6) infectious diseases in the past year, compared to 4.2 (4.1-4.4) in vaccinated children. Among 11- to 17-year-olds, the corresponding figures were 1.9 (1.0-2.8) (unvaccinated) versus 2.2 (2.1-2.3) (vaccinated). The lifetime prevalence of at least one atopic disease among 1- to 5-year-olds was 12.6% (5.0%-28.3%) in unvaccinated children and 15.0% (13.6%-16.4%) in vaccinated children. In older children, atopy was more common, but its prevalence was not found to depend on vaccination status: among 6- to 10-year-olds, the prevalence figures were 30.1% (12.9%-55.8%) for unvaccinated children versus 24.4% (22.8%-26.0%) for vaccinated children, and the corresponding figures for 11- to 17-year-olds were 20.3% (10.1%-36.6%) versus 29.9% (28.4%-31.5%).
CONCLUSION:
The prevalence of allergic diseases and non-specific infections in children and adolescents was not found to depend on vaccination status.
