EFFECT OF POLLUTANTS ON VACCINES IN CHILDREN

vaccinesVaccines administered to children are supposed to trigger production of antibodies which help the immune system to fight off infections. There are certain chemicals however, if present in the body of such children may slow down or even stop the vaccines from producing enough amounts of antibodies. This can lead to weakening of the immune system therefore making the child vulnerable and prone to infections. These substances are called PFOA and PFOS and are mainly located in the blood stream.

The chemicals are found in a class of compound known as Perfluorinated Compounds (PFCs) which have been yielded by the productions of chemicals used widely in homes. This is because of the fact that they make utensils and fabrics stain repellant and also they induce non stick properties. For example, Teflon and Scotchgard. These chemicals pollute the water and food. They end up being ingested by children leading to lower immune response even after immunization. The body is not able to produce enough antibodies to fight infections.

Many research scientists were shocked by such revelations especially Philippe Grandjean who is a physician at Harvard Medical school. His team carried out research by closely examining some 587 children in Denmark as they grew from birth until they were seven years old. The research was conducted by examining the amount of PFCs in their bloodstream. The children were immunized normally for infections such as tetanus and diphtheria.

The immune response of the children was the carefully checked over the years as they grew. It was discovered that those with a high concentration of the PFCs pollutant had a slow response to the vaccine. This proved that the chemical’s effect on the children was weakening the immune system. The response was the same before and after the shots.

With the slow immune response, it is feared that children might end up being vulnerable to allergic reactions, asthmatic attacks or even autoimmune diseases. Children who are more exposed to the PFOA, PFOS and another closely associated compound, have inadequate immune response with low antibody levels. It is clear that such children will be prone to illness if care is not taken.

Biologically response to toxins is majorly the role of the immune system to detect. In case of being exposed to PFOS, the antibody production is highly derailed hence when foreign bodies are introduced they may not be detected. With such incidences immunization will become obsolete as the process is made inactive as no antibodies are produced.

Toxicologists highly anticipate such findings especially those in the field. Cell based studies have also detected a similar problem brought about by the presence of PFOS and PFOA. Manufacturers may have decided to end the use of PFC compounds, Corsin Emanuela of University of Milan in Italy remarks that the chemicals remain as a great toxin threat.

Generally vaccines are produced for helping prevent infection in children. However, with production of PFC compounds such will be ineffective in helping prevent infection. It is important to do all it takes to make sure that children are healthy.

Monitoring Software

The Internet can be tricky for parents to deal with because kids often need to use the Internet for school, but parents parents are often worried about the various activities that their children might be engaged in. Peer-to-peer file sharing can lead to lawsuits and even a criminal prosecution. Some teens might engage in activities online that are embarrassing to the family or may lead to viruses or hackers accessing the computer. Fortunately, there are various forms of monitoring software that can offer parental control.

Monitoring software can also be very helpful when parents are trying to learn what their children are up to, such as whether they are attending class or doing their homework.

Many teens use the computer purchased specifically for schoolwork to play computer games or chat with friends. Monitoring software can not only record activities on the computer, but smartphone software such as Mobile Spy can silently record the teen's GPS information, text messages and phone call information.

Monitoring software sits silently on a computer or mobile device and monitors all of the activities carried out on the device, encouraging the teen to consistently use the device for communication. Activity is usually uploaded to an online account so that the parent can monitor activity from anywhere without having to get close to the phone. This is crucial since parents will usually not have physical access to the phone without arousing suspicion.

Many monitoring programs also come with keystroke loggers, which log keys recorded on the computer, a contextual blocker, and features that allow parents to block certain websites. All of these features allow parents to have a peace of mind when allowing their teens to use the Internet.
