Tdap Vaccine Study Provides More Evidence That Flu Vaccine Causes ASD

Whenever they try to clear vaccines of causing autism, the vaccine people implicate them more. The latest fairy tale evidence used in favor of vaccination is yet more evidence implicating influenza vaccination in autism spectrum disorder.

Last year, another large study by the health insurance industry showed influenza vaccination during pregnancy was associated with an increased ASD risk. This year, a study of Tdap ironically did the same by showing that not getting a flu vaccine was associated with a decreased risk for ASD among children whose pregnant mothers got the Tdap vaccine.

While the association was a decreased risk of 15%, last year’s influenza vaccine study showed a risk for ASD as high as 25% for first-trimester influenza vaccination.

The Tdap study is the second ASD-vaccine cohort study by Kaiser Permanente and the third by the insurance industry in the last three years. It is abundantly clear that as the increase in ASD continues, the insurance companies are increasingly going to have to pick up the tab. The doctors and drug companies are shielded from the litigation. The government won’t compensate for the ASD cases it caused. So the burden now falls on the health insurance industry.

And of course, the insurance industry gets pharma funding for vaccine studies. It is also a partner in the CDC’s Vaccine Safety Datalink Project. Finally, influenza vaccinations still contain the mercury-based preservative thimerosal.

JAMA Must Correct Study As Linking Flu Vax to Autism

Since the journal JAMA Pediatrics published a study which showed an association between flu vaccine and autism despite concluding there was none, scientists have published letters in the journal to complain. One of those was by Dr. Brian Hooker, biochemist and autism father who was the first person contacted by the CDC’s vaccine safety whistleblower William Thompson.

The study found an elevated risk for autism from flu vaccination in pregnant women during the first month of pregnancy. Yet the authors attempted to explain this away with incorrect statistical methods and then issued the flawed recommendation that no changes in vaccination policy should be made. In 2004, the CDC expanded its flu vaccine recommendations in pregnant women to include the first trimester of pregnancy. Many cite this an an explanation for why the reported CDC prevalence of autism – generally speaking – did not decline as the mercury-based preservative thimerosal had been removed from other vaccines. Thimerosal remains in multi-dose vials of flu vaccine given to pregnant women.

In Denmark, the reported autism prevalence went down by as much as a third as thimerosal was removed from childhood vaccines there during the 1990s. The elevated risk for autism associated with influenza vaccination during the first trimester of pregnancy was 20-25%. The potential implications of such a finding is profound.

The study was conducted by Kaiser Permanente, a Health Maintenance Organization (HMO) that is in partnership with the CDC and other HMOs in a heavily guarded federal research project known as the Vaccine Safety Datalink (VSD). JAMA journals’ publisher the American Medical Association sent a press release applauding a 2004 report from the Institute of Medicine that the CDC paid to have whitewash associations between vaccines and autism. The involvement of such institutions in the conduct and publication of such a study should only diminish public confidence in its integrity, along with its flawed conclusion and recommendation.

Nonetheless, the conclusion and recommendation should still be corrected. JAMA Pediatrics can be contacted here.
