Now, the argument should be over. This study effectively puts the nail in the coffin to the now disproven theory that the MMR vaccine is associated with or causes autism. Period.

My Take?

Even though there were many parents who, in the past, did not have their children vaccinated for the now disproven theory that vaccines cause autism, Reuters is reporting that U.S. toddlers got the recommended vaccinations against childhood diseases at record levels in 2007.

My Take?

The Miss America winner was reputed to have become permanently deaf because of a bad DTP vaccine, but this story was totally false. Her deafness actually occurred after she contracted bacterial meningitis caused by Haemophilus influenzae type b (Hib), a bacterium for which a vaccine has since become available. Fortunately, the Hib vaccine has virtually eliminated Hib meningitis and its resulting deafness. 

You can read more about vaccines and vaccine myths in my book God’s Design for the Highly Healthy Child.

In 1999, a study revealed that the preservative thimerosal, a mercury-containing compound present in many vaccines, caused several infants to have levels of mercury in their blood that exceeded guidelines recommended by the Environmental Protection Agency (EPA).

Preservatives are used in vaccines to reduce the risk of contamination by bacteria once the vial is opened. 

Exposure to high levels of mercury, especially in the developing child before birth, is associated with neurological disturbances. Therefore, parents began to fear that thimerosal may cause neurological difficulties, like autism.

When this study was first described, physicians, scientists, and public health officials quickly assessed the situation and found that:

Natural infection with certain viruses can weaken the immune system. So when children are infected with one virus, they can’t fight off other viruses or bacteria as easily. 

This happens most notably during natural infection with chicken pox or measles. Children infected with chicken pox are susceptible to certain bacterial infections (MRSA or flesh-eating bacteria, for example). 

Children infected with measles are more susceptible to bacterial infections (resulting in sepsis) of the bloodstream. 

But vaccines are different.

It is true that natural infection almost always causes better immunity than vaccination. In fact, only the Hib and tetanus vaccines are better at inducing immunity than natural infection.

Natural infection causes immunity after just one infection, but vaccines usually create immunity only after several doses over a period of time.

The Myth - Infants are too young to get vaccinated.

The Truth - It’s very important to make sure that infants are fully immunized against certain diseases by the age of six months.

Despite what is often falsely reported in the media and at many scaremongering web sites, all recommended vaccines are extraordinarily safe. 

When you consider that the 3.5 to 4 million children born every year in the United States receive more than twenty different vaccines to protect them from at least eleven different preventable diseases by the time they are six years old, and that some of these vaccines have existed for more than fifty years, I think you’ll agree that the record of vaccine safety in this country is remarkable.
