Vaccine Ineffective If The Exposed to Chemicals

Chemical compounds are perfluorinated compounds (PFCs) are widely used in everyday equipment such as bags of food wrap, carpet to nonstick cookware. Exposure to these chemicals can result in a vaccinated child so it is not immune.

Found that higher levels of PFCs in the blood, the fewer antibodies produced by the body after the children were given diphtheria and tetanus vaccines.

Children are more exposed to PFCs also have low levels of antibodies that can not provide protection against infectious diseases.

Exposure to PFCs cause the immune system is weaker children when vaccinated. In addition to making antibodies do not work, your body will also produce some antibodies.

The number of antibodies produced by the vaccine is an indication of immune system function properly. These findings suggest that the PFC has a negative effect on the immune system, even beyond the effects of the vaccine.

Although not yet able to identify how PFC can enter the body, experts suspect food, drinking water and chemicals contaminated products could be a major source of exposure to PFCs. Animal studies have found links between exposure to PFCs with changes in immune function.

To determine whether the chemical can affect the human immune system, Grandjean and her team took blood samples from 587 pregnant women in 1999 to 2001.

Researchers then tested the samples for the presence of the five most common types of PFCs encountered. When the children born reached the age of 5 years, researchers repeated the same process by using blood samples from children.

All the children and mothers in this study lived in the Faroe Islands are located between Iceland and Scotland. Faroe Islands have many sources of PFC contaminated food and eating whale meat from contaminated waters. The average levels of PFCs in the blood of children Faroe PFC levels comparable to American children.

The researchers also measured levels of diphtheria and tetanus antibodies in children's blood twice. First at the age of 5 years after the children had been given three doses of tetanus vaccine and the second is two years later when the children were injected with vaccine boosters.

The high PFC exposure before birth associated with decreasing the amount of antibodies at the age of 5 years. Children whose blood showed a lot of exposure to PFCs at age 5 years had fewer antibodies when he was 7 years old. PFC exposure at age 5 years to double the amount estimated to reduce by half of the antibody when the age of 7 years.

If a child is vaccinated, including the children who are exposed to PFC so it does not respond to the vaccine, the possibility of an epidemic could be higher than the level of vaccination.

That it is impossible to completely avoid PFC because this material is pervasive in the environment. PFC-free products do exist, but tend to be expensive and hard to find.

Children and adults can be exposed to PFCs in food through a food container. Unfortunately, what the exact number of PFC levels that can be mixed in food remains unclear.
