For decades, the medical and scientific communities have been attempting to discover the causal factors for autism spectrum disorder because during the last few decades its prevalence has dramatically risen. This, of course, is a major problem because the debilitating disorder can make everyday activity a struggle. With that said, some previous investigators have presumed the onset of autism is due to genetic mutations while others suggest diagnostic substitution from other diagnoses, such as mental retardation (MR) and/or cerebral palsy (CP) to pervasive developmental disorder (PDD), are contributing factors behind the increased rates of autism.
However, this suggestion of diagnostic substitution made autism researchers and expert David A. Geier investigate that theory of autism onset. They examined medical records with SAS® and StatsDirect software for subjects within the Vaccine Safety Datalink database that were HMO-enrolled at birth until they were diagnosed with an International Classification of Disease (ICD-9) outcome of PDD, MR or CP. After examination of the data, they suggest that diagnostic substitution cannot fully explain the increased prevalence of PDD during the 1990s in the United States.
Autism falls under the diagnostic category of pervasive development disorders (PDD) and the diagnosis typically occurs before a child reaches the age of 3. They may demonstrate problems with social and communication skills like difficulties relating to people, playing with toys in unusual ways and showing body movement or behavior patterns in a repetitive manner. At any rate, the researchers cite that the prevalence of PDD has increased 20 to 30 fold since studies were conducted during the ’60s and ’70s as it was estimated to only affect 1 in 2,500 children or 0.04%. However, by the 2000s, the prevalence changed to 1% to 2% of all children.
The goal was to find out why it rose and previous research was attempting to presume the increase was due to diagnostic substitution from other diagnoses was the ultimate reason. But, that was not the case as the data from the VSD database was significantly different populations and the differences in that diagnostic substitution cannot explain the increase of PDD cases in the US. Additionally, as time progressed, more environmental factors have come into play like the number of childhood vaccinations, which many of the vaccines are formulated with toxic compounds like aluminum and mercury. Both toxins have been extensively study and research has produced strong evidence that they can affect the central nervous system and neurodevelopment. All of which purport toxic exposure and the possible onset of autism spectrum disorder and other neurological conditions.
There are a number of substances and chemicals that have proven harmful and pose a threat to the health of people. The Food and Drug Administration (FDA), Centers for Disease Control and Prevention (CDC), public health officials and medical professionals have worked to safeguard individuals by eliminating or removing substances that can cause diseases and/or illness. However, parents and individuals have raised much concern regarding mercury found in the flu vaccine and its connection to illnesses.
Although flu shots are promoted as safe and effective at shielding individuals from getting sick, because of the mercury found inside of them, they can present a risk. While the FDA claims that the amount of mercury used is at a safe level, there is no safe level of any toxin. Any level of a substance, chemical or toxin injected into the body can pose a threat in many ways. Scientist David Geier explores the use of mercury in vaccines and the effects that follow.
The Harmful Effects of Mercury isn’t New
The toxicity of mercury and its threat to human health is nothing new. In fact, many schools and retail stores have removed mercury-induced items such as thermometers and thermostats because the mercury inside these items poses risk. Children are most frequently exposed to mercury when it is mishandled or improperly cleaned up.
But it’s not just about mercury being toxic that poses risk. What we must also factor in the fact that everyone has different levels of susceptibility to its effects. Every individual has a different level of tolerance for mercury and will react differently. Yet when given the flu shot, every individual is given the same amount of mercury. Therefore, those with weaker immune systems are not likely to react as strongly as those with stronger immune systems.
Mercury in Vaccines
Thimerosal is a mercury-based preservative used in vaccines. Vaccines are produced in multi-dose vials or single-dose units. The multi-dose units use thimerosal as a preservative in order to prevent accidental contamination of the vial. According to the CDC, because the amount of mercury in thimerosal is present in trace amounts, it does not pose a threat to health. The single-dose units are created without thimerosal since they are intended to be used only once.
David Geier has worked effortlessly and conducted years of research into the effects of mercury toxicity and its relationship to various illnesses and disorders in order to raise awareness.
Taking your child to get vaccinated is no easy task. Every parent wants their child to be healthy, but can naturally be a little worried about getting their child vaccinated. There are so many risks and unknown factors when it comes to childhood vaccinations, and it’s only natural that parents want to make sure that the shots they’re giving their kids are effective and aren’t dangerous. Autism and vaccine experts like David Geier want to help parents and put the power back into their hands when it comes to vaccine information and decisions. If you’re concerned about your child’s vaccinations, there are some questions you should have answers to before you take them to the doctor.
Have I or any family members had adverse reactions to vaccines?
You’re worried about how your child will react to a vaccination, but you should really be concerned about yours and your family’s history of vaccine reactions. Your family’s medical history can tell you a lot about how your child will react when they’re vaccinated. Do you remember getting sick after getting a shot? Are any of your family members allergic to certain vaccines? If you remember you or your family having any difficulties, you should discuss your concerns with doctors.
Do I have information about side effects?
When we say information about side effects, we don’t mean general information about what could go wrong with vaccines. Every vaccine is different, and certain side effects that can happen with one may not happen with the other. Take time to research the specific vaccine your child will be getting, and the potential side effects that are associated with it. While we’re on the topic of knowing about potential side effects, we should mention the importance of having the answer to the following question of…
Do I know how to identify a serious reaction to a vaccine?
A low fever after getting a shot isn’t very worrisome, but a high fever or a fever that lasts for days should be cause for concern. Minor redness or swelling around the injection site is very normal, but bruising, the appearance of pus, or moderate pain can be the beginning signs of a bad reaction. It can be easy to identify anything out the ordinary as a sign of severe reaction, and worrying your doctor or your child won’t do any good. Before you start to panic or take them to a doctor, make sure that you know that you’re dealing with something serious.
