Immune Suppression by Live Virus-Containing Vaccines

It is also known that certain viruses powerfully suppress immunity, including the measles virus. The MMR vaccine contains live measles viruses and recent studies have shown that immune suppression after vaccination with this virus suppresses immunity in a profound way that last as long as 6 months. In fact, the CDC recommends separating this vaccine from other live virus vaccines to prevent viral overgrowth (Yet, they combine it with two other live viruses—rubella and mumps viruses).

Yet, they never address the obvious question: wouldn’t this vaccine also make the child more susceptible to other naturally occurring infections such as Haemophilus influenzae type B, meningitis, meningococcal meningitis, persistent measles infection, influenza infection, and even chickenpox? This has been strongly suggested by a number of studies. Not only would they be more susceptible, but severe complications and even death would be more common as well.

When death and severe complications occur due to these infections, pediatricians, the CDC and the American Academy of Pediatrics use this as a justification for more vaccines, never admitting that the increased incidence of these infections and complications was caused by their previous vaccine recommendations.

This risk is especially high in families with a number of other children in the household or in children in day care centers. With prolonged suppression of the immune system, exposure to other sick children would put this child at a high risk of contracting the infection and having complications or dying from the infection as stated.

Studies have also shown that vaccines that cover only a few strains of a virus or bacteria that naturally have a great number of strains (some have more than a hundred strains), can cause a shift in strain dominance so that the strain not included in the vaccine then becomes the dominant disease-causing strain. We see this with the meningococcal and pneumococcal vaccines. This is discussed in the scientific literature but the public is never informed. Most pediatricians are completely unaware of this.

When combined with mercury, which is also an immune-suppressing substance, the effect is compounded. Fluoroaluminum, formed in fluoridated drinking water, also interferes with immune function, as do many insecticides and herbicides used around the home.

Often forgotten, is the substantial evidence that omega-6 oils powerfully induce inflammation and immune suppression when consumed in large amounts. Those eating a Western diet are consuming 50-fold higher amounts of this type of oil (called linoleic acid) than needed for health. These oils include corn, safflower, sunflower, canola, peanut, and soybean oils. So, we see that the average child is exposed to a number of substances in their food and environment that can also alter immunity, making them not only more susceptible to natural infection, but also to vaccine complications.

In essence, by over-vaccinating our children, public health officials are weakening their immune system, making them more susceptible to a number of infections and less able to combat the infections. This gives them an endless source of “horror stories” to justify even more vaccines. Remember also that mercury is an immune suppressant, from both vaccines and seafood contamination.

One can see that a pregnant mother having dental amalgam fillings who eats a diet high in methylmercury-containing seafood and living in an area with high atmospheric mercury, such as West Texas, would be at a greater risk of having an autistic child than one not exposed to these other sources of mercury. These differences in environmental mercury exposure are never considered by those insisting all children have the same vaccines, including mercury-containing vaccines such as the flu vaccine.

The Autistic-Prone Child

It is becoming obvious that certain children are at a higher risk of developing autism than others, for a variety of reasons. It is also obvious that these newborns and small children develop infections at a higher rate than less vulnerable children. This may be due to a developmental immune deficiency, which can affect only a portion of the immune system and may be easily missed by their pediatrician. Indeed, it has been noted that a great number of cases of childhood immune deficiencies are missed by practicing pediatricians, especially the more subtle cases, which may make up the majority of ASD-prone children.

For example, many physicians treating autistic children have noted a high incidence of ear infections. These are treated with broad-spectrum antibiotics, which often lead to a high incidence of Candida overgrowth in the child’s body. Both infections will prime the microglia in the child’s brain—which is the brain’s specific resident immune cell. This priming effect shifts these normally resting microglia immune cells into overdrive. If stimulated again within weeks or even months, they generate extremely high levels of free radicals, lipid peroxidation products, inflammatory cytokines, and the excitotoxins glutamate and quinolinic acid. Studies have shown that this is the major mechanism for both viral and vaccine-related brain injury.

The high incidence of infection in these children indicates the possibility of a preexisting immune system dysfunction. As stated, this also increases the risk of an autoimmune reaction. The stage is then set for the autism cascade to develop and this can be triggered by early vaccination or a recurrent infection. Remember, the microglia have been primed, either by a natural infection or an earlier vaccination (such as the hepatitis B vaccine given soon after birth). The vaccine is different from a natural infection in that the vaccine produces immune stimulation in the brain for very prolonged periods.

It has been proven, in both animal and human studies, that systemic infections or immune activation by vaccines rapidly activate the brain’s microglial system and can do so for prolonged periods. Once the primed microglia are reactivated by the subsequent vaccination or infection, the microglia activate fully and pour out their destructive elements as discussed above.

With a natural infection, the immune system quickly clears the infection and then shuts off the immune activation, which allows the damage to be repaired. This shutting down of the microglia is very important. There is evidence that with repeated and excessive vaccine-triggered immune stimulation, the microglia do not shut down. This is what was found in the Vargas, et al, study, in which they examined the brains of 11 autistic people from age 5 years to 44 years of age who died without active infectious diseases as compared to age-matched controls. That is, they found widespread activation of inflammatory cells (microglia and astrocytes) in the brains of the autistic patients. This explains the widespread brain damage seen in all autism cases.

This study was one of the most carefully conducted, extensive examinations of the immune reactions in the autistic brain ever done and involved immunocytochemistry, cytokine protein assays, and enzyme-linked immunoascorbant assays of the brain tissue. They also performed similar assays of spinal fluid from an additional 6 living autistic patients, which confirmed the intense immune activation and inflammation.

The average child receiving all of the recommended vaccines will have some 23 inoculations by age 2 years and 36 by the time they enter school. Most of these will be spaced within 1 month of each other, which means the priming and activation cycle of the microglia will be continuous. In addition, should they follow the new CDC recommendation they will receive the flu vaccine every year starting at age 6 month through age 18 years. These vaccines contain a full dose of thimerosal mercury.

In addition, we must consider the effect of the measles and rubella portions of the MMR vaccine, which begins at age 1 year. The profound immune suppression, which last up to 6 months after it is given, will not only increase the risk of developing other infections, but will increase the risk of an autoimmune reaction. Cytomegalovirus is also a powerful immune-suppressing virus that commonly infects newborns and small children, especially if they are immune suppressed. So, we see that giving a live, immunosuppressant vaccine early in life can dramatically increase the risk of autoimmune disorders and increase microglial brain injury, as well as increase the risk of infection by other immune-suppressing viruses and pathogenic organisms. And, it dramatically increases the risk of your child developing one of the autism spectrum disorders.

It should also be appreciated that the Candida infections in these children trigger a prolonged systemic immune reaction, which means a prolonged brain immune response as well and a worsening of any autoimmune disorder it may have produced.
