Kids & Autism: Peer-Reviewed Studies That Make Anti-Vaxxers Squirm

Posted by Jerry De Luca on Saturday, July 9, 2016

See “Anti-Vaxxers Aren’t Welcome at My Practice” below

Following the three videos is just a small sampling of peer-reviewed research exposing anti-vaxxers.

“In this large sample of privately insured children with older siblings, receipt of the MMR vaccine was not associated with increased risk of ASD (autism spectrum disorders), regardless of whether older siblings had ASD. These findings indicate no harmful association between MMR vaccine receipt and ASD even among children already at higher risk for ASD.”   http://jama.jamanetwork.com/article.aspx?articleid=2275444

“In this study of managed care organization members, increasing exposure to antibody-stimulating proteins and polysaccharides in vaccines during the first 2 years of life was not related to the risk of developing an autism spectrum disorder.”   http://www.ncbi.nlm.nih.gov/pubmed/23545349

“As persistent infections are typically associated with high antibody levels, our results support the arguments against a role of measles-mumps-rubella (MMR) vaccination as a causal factor or co-factor in development of autism spectrum disorders.”   http://www.ncbi.nlm.nih.gov/pubmed/23606694

“The California Department of Developmental Services (DDS) data do not show any recent decrease in autism in California despite the exclusion of more than trace levels of thimerosal from nearly all childhood vaccines. The DDS data do not support the hypothesis that exposure to thimerosal during childhood is a primary cause of autism.”   http://www.ncbi.nlm.nih.gov/pubmed/18180424

“Timely vaccination during infancy has no adverse effect on neuropsychological outcomes 7 to 10 years later. These data may reassure parents who are concerned that children receive too many vaccines too soon.”  http://www.ncbi.nlm.nih.gov/pubmed/20498176

“In 1998, the English physician Andrew Wakefield suggested that the MMR vaccine insults the guts of children who then regress developmentally and become autistic. Although his research did not provide firm evidence for this hypothesis, many believe that (a) the MMR vaccine can cause autism; (b) children with autism typically have gastrointestinal problems; and, (c) a necessary component of treating autism is ‘treating the gut’ through dietary restrictions. Research has subsequently shown that Wakefield's hypothesis is unquestionably false, children with autism are not more likely to have gastrointestinal problems, and there is no sound evidence that diets are a valid treatment for autism. This paper will critically review these topics.”   http://www.ncbi.nlm.nih.gov/pubmed/22479671

“The evidence presented does not show a causal relationship between the measles-mumps-rubella (MMR) vaccine and autism. Myths presented to potentially support any relationship between the MMR vaccine and autism have not been proven. Expert testimony refuting initial scientific theories has led to Supreme Court decisions that do not support a link between the MMR vaccine and autism. Pharmacists and all health care providers are responsible for informing and educating parents and families regarding this information so that they can make informed decisions about immunizations.”   http://www.ncbi.nlm.nih.gov/pubmed/21071320

“Concerns have been raised that children may be receiving too many immunizations under the recommended schedule in the USA. We used a publicly available dataset to evaluate the association between antibody-stimulating proteins and polysaccharides from early childhood vaccines and neuropsychological outcomes at age 7-10 years …. We did not find any adverse associations between antigens received through vaccines in the first two years of life and neuropsychological outcomes in later childhood.”  http://www.ncbi.nlm.nih.gov/pubmed/23847024

“Although immunization is known to provide effective life-saving benefits for children, it has sometimes been blamed for an array of diseases that have unknown causes (eg, autistic spectrum disorder [ASD], multiple sclerosis and sudden infant death syndrome). This is not surprising, given that immunizations are common and that humans are primed to attribute causality to events that precede an incident. We all use the ‘after it, because of it’ logic. This is how we learned not to touch a hot stove as young children. Unfortunately, this logic can be faulty. Causality assessment requires careful consideration of a wide range of factors. Beyond the temporal relationship, the consistency of the finding, the strength of the association, the specificity of the association and the biological plausibility, all need to be evaluated before attributing causality. The present article reviews recent controversies surrounding immunizations and ASD, and concludes that there are no data to support any association between immunization and ASD.”      

“Adverse Effects of Vaccines reviews the epidemiological, clinical, and biological evidence regarding adverse health events associated with specific vaccines covered by the National Vaccine Injury Compensation Program (VICP), including the varicella zoster vaccine, influenza vaccines, the hepatitis B vaccine, and the human papillomavirus vaccine, among others. For each possible adverse event, the report reviews peer-reviewed primary studies, summarizes their findings, and evaluates the epidemiological, clinical, and biological evidence. It finds that while no vaccine is 100 percent safe, very few adverse events are shown to be caused by vaccines. In addition, the evidence shows that vaccines do not cause several conditions. For example, the MMR vaccine is not associated with autism or childhood diabetes. Also, the DTaP vaccine is not associated with diabetes and the influenza vaccine given as a shot does not exacerbate asthma.”   

“Twenty epidemiologic studies have shown that neither thimerosal nor MMR vaccine causes autism. These studies have been performed in several countries by many different investigators who have employed a multitude of epidemiologic and statistical methods. The large size of the studied populations has afforded a level of statistical power sufficient to detect even rare associations. These studies, in concert with the biological implausibility that vaccines overwhelm a child’s immune system, have effectively dismissed the notion that vaccines cause autism.”   http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2908388/

“The increased diagnoses of autism and developmental disorders in recent decades, together with the childhood vaccination program, has led to the hypothesis that vaccination in general, and the measles, mumps, and rubella virus live vaccine, and vaccines that contain mercury, in particular, cause autism. It has been hypothesized that intestinal infection caused by live virus vaccines change the permeability of the intestinal wall, and subsequently, the passage of peptides through the intestinal wall to the blood, and from there to the brain. It has been suggested that the accumulation of these peptides in the central nervous system causes autism. Studies that investigated this theory did not find an association between vaccine administration and between digestive system symptoms and autism.

“According to a second hypothesis, an organomercury compound (Thimerosal), used as a preservative in vaccines that do not include live viruses, is a cause of autism. Like the former, this hypothesis has been well researched, and refuted. Some studies have in fact found an increase in autism diagnosis among children who were vaccinated after Thimerosal was removed from the vaccine preparation. Recent studies have refuted the theory that the consecutive administration of vaccines weakens the young immune system in children, and leads to an autoimmune process that causes autism. The etiology of autism is still unknown, with research continuing from different directions. The extensive research conducted so far indicates that childhood vaccination is not a cause of the sharp increase in autism diagnoses in recent decades.”   http://www.ncbi.nlm.nih.gov/pubmed/20812501

“There has been enormous debate regarding the possibility of a link between childhood vaccinations and the subsequent development of autism. This has in recent times become a major public health issue with vaccine preventable diseases increasing in the community due to the fear of a ‘link’ between vaccinations and autism. We performed a meta-analysis to summarise available evidence from case-control and cohort studies on this topic (MEDLINE, PubMed, EMBASE, Google Scholar up to April, 2014). Eligible studies assessed the relationship between vaccine administration and the subsequent development of autism or autism spectrum disorders (ASD) ….. Five cohort studies involving 1,256,407 children, and five case-control studies involving 9,920 children were included in this analysis.

“The cohort data revealed no relationship between vaccination and autism or ASD, nor was there a relationship between autism and MMR, or thimerosal, or mercury. Similarly the case-control data found no evidence for increased risk of developing autism or ASD following MMR, Hg, or thimerosal exposure when grouped by condition or grouped by exposure type. Findings of this meta-analysis suggest that vaccinations are not associated with the development of autism or autism spectrum disorder. Furthermore, the components of the vaccines (thimerosal or mercury) or multiple vaccines (MMR) are not associated with the development of autism or autism spectrum disorder.”    http://www.sciencedirect.com/science/article/pii/S0264410X14006367

Anti-Vaxxers Aren’t Welcome at My Practice

“According to a new study in the journal Pediatrics, about 20 percent of pediatric practices dismiss patients whose parents refuse one or more of the standard vaccines recommended during infancy. Mine would likely count as one of them. Though we don’t technically ‘fire’ patients for not getting vaccinated, we don’t accept them to our practice in the first place, which is close enough.” http://www.thedailybeast.com/articles/2015/11/03/anti-vaxxers-aren-t-welcome-at-my-practice.html

A biologist and researcher exposes the flaws and fallacies of anti-vaccine arguments:

“As you read through this, I want you to pay very careful attention to an important difference between the original article and my rebuttal. Namely, the ‘sources’ for the original were almost entirely quack websites like Natural News, Whale.to, Info Wars, etc. Indeed, there were only citations to a few (I think three) peer-reviewed papers in the entire post, and most of them weren’t about vaccines. In contrast, I constantly back up my claims with peer-reviewed studies or statistics from reputable groups like the CDC and WHO. I may direct you to blogs for more detailed explanations, but I always back up factual claims with proper sources. On that note, if you disagree with my arguments, please do not bother to post unless you include references to the peer-reviewed literature. To be blunt, I do not give a crap about your anecdotes, gut feelings, opinions, or ‘hours of research.’ Unless you can back up your position with properly conducted studies, your position is invalid.”

Side Effects: 

“Any vaccine can cause side effects. For the most part these are minor (for example, a sore arm or low-grade fever) and go away within a few days. Listed below are vaccines licensed in the United States and side effects that have been associated with each of them …… Remember, vaccines are continually monitored for safety, and like any medication, vaccines can cause side effects. However, a decision not to immunize a child also involves risk and could put the child and others who come into contact with him or her at risk of contracting a potentially deadly disease.”   http://www.cdc.gov/vaccines/vac-gen/side-effects.htm
