The poisonous public attacks on Katie Wright this week–for revealing that her autistic son Christian (grandson of NBC Chair Bob Wright), has recovered significant function after chelation treatments to remove mercury ­ surprised many observers unfamiliar with the acrimonious debate over the mercury-based vaccine preservative Thimerosal.

But the patronizing attacks on the mothers of autistic children who have organized to oppose this brain-killing poison is one of the most persistent tactics employed by those defending Thimerosal against the barrage of scientific evidence linking it to the epidemic of pediatric neurological disorders, including autism. Mothers of autistics are routinely dismissed as irrational, hysterical, or as a newspaper editor told me last week, “desperate to find the reason for their children’s illnesses,” and therefore, overwrought and disconnected.

But my experience with these women is inconsistent with those patronizing assessments. Over the past two years I’ve met or communicated with several hundred of these women. Instead of a desperate mob of irrational hysterics, I’ve found the anti-Thimerosal activists for the most part to be calm, grounded and extraordinarily patient. As a group, they are highly educated. Many of them are doctors, nurses, schoolteachers, pharmacists, psychologists, Ph.D.s and other professionals.

Many of them approached the link skeptically and only through dispassionate and diligent investigation became convinced that Thimerosal-laced vaccines destroyed their children’s brains. As a group they have sat through hundreds of meetings and scientific conferences, and studied research papers and medical tests. They have networked with each other at meetings and on the Web. Along the way they have stoically endured the abuse routinely heaped upon them by the vaccine industry and public health authorities and casual dismissal by reporters and editors too lazy to do their jobs.

Many of these women tell a story virtually identical to Katie Wright’s ­ I have now heard or seen this grim chronology recounted hundreds of times in conversations, e-mails and letters from mothers: At 2-1/2 years old, Christian Wright exceeded all milestones. He had 1,000 words, was toilet-trained, and enjoyed excellent social relations with his brother and others.

Then his pediatrician gave him Thimerosal-laced vaccines. He cried all night, developed a fever and, over the coming months, this smart, healthy child disappeared. Christian lost the ability to speak, to interact with family members, to make eye contact or to point a finger. He is no longer toilet trained. He engaged in stereotypical behavior–screaming, head-banging, biting and uncontrolled aggression, and suffers continuously the agonizing pain of gastrointestinal inflammation.

After hearing that story a couple dozen times, a rational person might do some more investigation. That’s when one encounters the overwhelming science ­ hundreds of research studies from dozens of countries showing the undeniable connection between mercury and Thimerosal and a wide range of neurological illnesses. In response to the overwhelming science, CDC and the pharmaceutical industry ginned up four European studies designed to disguise the link between autism and Thimerosal.

Their purpose was to provide plausible deniability for the consequences of their awful decision to allow brain-killing mercury to be injected into our youngest children. Those deliberately deceptive and fatally flawed studies were authored by vaccine industry consultants and paid for by Thimerosal producers and published largely in compromised journals that neglected to disclose the myriad conflicts of their authors in violation of standard peer-review ethics. As I’ve shown elsewhere [see www.robertfkennedyjr.com], these studies were borderline fraud, using statistical deceptions to mislead the public and regulatory community.

The CDC and IOM base their defense of Thimerosal on these flimsy studies, their own formidable reputations, and their faith that journalists won’t take the time to critically read the science. The bureaucrats are simultaneously using their influence, energies and clout to derail, defund and suppress any scientific study that may verify the link between Thimerosal and brain disorders. (These would include epidemiological studies comparing the records of vaccinated children with those of unvaccinated populations like the Amish or home-schooled kids who appear to enjoy dramatically reduced levels of autism and other neurological disorders.)

The federal agencies have refused to release the massive public health information accumulated in their Vaccine Safety Database (VSD) apparently to keep independent scientists from reviewing evidence that could prove the link. They are also muzzling or blackballing scientists who want to conduct such studies.

Ironically, it is the same voices that once blamed autism on “bad parenting,” and “uninvolved” moms that are now faulting these mothers for being too involved.

Due to this campaign of obfuscation and public deception, Thimerosal-based vaccines continue to sicken millions of children around the world and potential treatments ­ like the chelation that benefited Christian Wright ­ are kept out of the hands of the mainstream doctors now treating autistic kids with less effective tools. Like thousands of other mothers of autistic children, Katie Wright knows what sickened her child. Her efforts to spare other families this catastrophe, deployed with a cool head and calm demeanor, are truly heroic.

Maybe it’s time we all started listening. Maybe it’s time to start respecting and honoring the maternal instincts and hard work of Katie and her fellow mothers by aggressively funding the studies that might verify or dispute them.
