Nature programs us to seek out and discover new things as infants. And nature has also seen fit to have infants immediately put in their mouth just about everything they find on the floor or the ground.
And they find lots of things just loaded with all sorts of germs. While you might be inclined to try to prevent this, there is more and more evidence that infants actually need this exposure to germs. Instead of trying to shield your child from germs, allowing the child to naturally develop immunities by exposure to all the normal germs out there may prove beneficial later on.
A recent study supports this. Researchers found that people who grow up with younger siblings close to them in age are less likely to develop multiple sclerosis (MS) than those without such siblings.1 People who had one to five years of contact with their infant siblings had about half the chance of later developing MS compared to people with less exposure.2 As they wrote, “Sloppy kisses from baby brothers and sisters might fend off disease in later years.”3 The study suggests that exposure to infection early on teaches the immune system how to fight these same diseases later in life and how to distinguish between real foreign threats to the body and its own cells. MS is specifically sited as one disease that may be avoided from early exposure to germs because it is caused by the body’s immune system turning on itself.4
Previous studies also support this. One found that children raised in a house with two or more dogs or cats during the first year of life may be less likely to develop allergic diseases and were on average 66 to 77 percent less likely to have any allergic antibodies to common allergens as compared with children raised without pets.5 The pets bring into the house all sorts of germs and allergens that help to teach the immune system not to overreact to these things down the road. Then there was a study that found that only 12% of children with numerous siblings or who were exposed to day care with other children in their first 6 months became asthmatic compared to 21% of children with no day care exposure and no more than one other sibling. So exposure to other children with all their infections and germs reduced the risk of asthma.6 Still a third study of nearly 1000 children found that children who did not contract the normal childhood illnesses were more prone to asthma and allergies later in life7 suggesting the actual disease builds a stronger immune system than vaccinations. 
This same line of reasoning has led some scientists and many chiropractic doctors to question the widespread use of many vaccinations in infants and children. Vaccines expose the immune system to a weakened version of a disease but may not develop and strengthen the immune system as well as overcoming the actual disease. There was a time when parents intentionally exposed their children to the common childhood diseases like mumps, measles, and chicken pox so that they would be immune later as adults when these diseases can be far worse. Now most children are vaccinated for these. Certainly some diseases like polio or smallpox in the past had serious enough consequences to possibly justify vaccination, but for the less serious childhood diseases, some question if the body would not be better off building its immune system.
There are other issues with vaccinations that parents should know about. Many vaccines themselves present risks. One of these risks is the presence of a preservative called Thimerosal, which is a mercury derivative.8 “Mercury is a toxic chemical that can cause permanent brain and nervous system damage to the developing bodies of unborn babies and young children.”9 Even modest doses can cause numbness in fingers and toes, impairment of motor coordination and speech, drowsiness, memory problems and tremors.10 Thimerosal has been used to preserve vaccines since the 1930’s. While in recent years its use has begun to decline, it is still in use and with the increasing number of vaccines being given to children each year, parents should be aware of the risks involved. Often vaccines are available both with and without Thimerosal and if parents choose to have their children vaccinated at all, they should insist on the ones without the mercury. You can find which do and which do not, and add up the total mercury dosage your child may be getting (or has already received) and learn much more about vaccinations by visiting the website of the National Vaccine Information Center at www.909shot.com/Issues/mercury.htm
While infant and child vaccinations have been increasing so have childhood developmental disabilities. The Center for Disease Control estimates that one in six American children are developmentally delayed with a diagnosis of autism, learning disabilities, attention problems or other learning or behavioral problems and as many as one in 166 specifically with autism.11 And a recent detailed study using data from the CDC concluded “The results of the present study, taken with data recently published by a number of researchers, demonstrate a connection between mercury exposure via infant vaccinations and the dramatic increase in autism and other neurodevelopmental disorders in the United States.”12 That study found over 53 million DTaP13 vaccines containing Thimerosal were administered between 1997 through 2000 compared with fewer than 17 million of that vaccine without the mercury. So Thimerosal is still an issue in vaccines that parents need to know about.
We are not saying parents should or should not have children vaccinated. That is up to you the parents. But we are saying you should learn about vaccines and make informed decisions for yourself. The NVIC website has a wealth of information. And we are saying that exposure of infants and children to germs and childhood diseases is normal and natural and likely is beneficial to the developing immune system.
