Does Mercury Cause Autism?

More importantly, does the preservative, thiomerosal, a mercury compound that is used as a preservative for multi-dose vaccines so they can be taken from the same vial without contaminating it, cause autism in children who take those vaccinations?

Reports of autism cases per 1,000 children grew dramatically in the US from 1996 to 2007. It is unknown how much, if any, growth came from changes in autism’s prevalence. (Photo credit: Wikipedia)

A 2011 scientific article called the vaccine-autism connection the most damaging medical hoax in the last 100 years.

If Robert F. Kennedy, Junior believed it when he wrote an article about CDC’s own study in 2005, why are scientists still saying there’s nothing to it?

How Did This Rumor Get Started?

In 1998, a British gastroenterologist claimed that autism could be triggered by environmental factors, like the measles, mumps, rubella (MMR) vaccination.

After 10 years of investigation, he was found guilty of ethical, medical and scientific misconduct. The data he had presented was fraudulent.

In 2003, a former NIH researcher published a paper linking autism and vaccines.

The American Academy of Pediatricians found the scientist’s methods flawed and conclusions unsupported.

His medical license was suspended in 2011.

Is Autism Increasing?

The Centers for Disease Control and Prevention (CDC) says, yes, the number of cases is rising.

They’re not sure why, but list several possible factors that they believe all contribute to the rise:

  • Better diagnosis so doctors recognize it more often
  • Broader definition of autism spectrum disorders (ASDs)
  • Possibly a true increase in the number of people with ASDs for an unknown reason.

People with ASD are now believed to represent one percent of the population, much higher than previously thought.

Autism was added as a special education category for public schools in the early 1990s.

By 2010, nearly 420,000 children between 3 and 21 were receiving special education services for autism.

For children between 6 and 21, autism represents about 6% of the special education population.

A CDC survey in 2000 found autism rates for children lower than for intellectual disability/mental retardation, but higher than for cerebral palsy, hearing loss or vision impairment among eight-year-olds.

What Is the Current Status of Thiomerosal?

In 1999, the CDC and the American Academy of Pediatricians (AAP) asked vaccine manufacturers to remove thiomerosal from vaccines.

No vaccines recommended for children contain the mercury-based preservative and it is being eliminated from all vaccines.

It remains in some flu vaccines.

Have you heard parents say they are not going to get their children vaccinated?

Have your grandchildren had their shots?

Do you know anyone who is autistic?

To you and the continued good health of your grandchildren.
