The counties where the anti-vaccine movement thrives in the US | Health

While working in the Northeast, I had heard a few things about the anti-vaccine movement. As both a vaccine scientist and a father of four, including a daughter diagnosed with autism and intellectual disabilities, I followed the emergence of doubt over vaccine safety in the general public. Ultimately, in scientific circles, any debate ended when an overwhelming body of scientific evidence demonstrated there was no association between vaccines and autism.

But then, in 2011, I relocated to Houston’s Texas Medical Center. I soon learned that, unlike in the Northeast, where the anti-vaccine movement so far seems restricted to small groups, the Texas anti-vaccine movement is aggressive, well-organized and politically engaged.

There are now at least 57,000 Texas schoolchildren being exempted from their vaccines for nonmedical reasons, about a 20-fold rise since 2003. I say “at least” because there is no data on the more than 300,000 homeschooled kids.

I then began to wonder about other parts of the U.S. Together with colleagues from Baylor College of Medicine and Texas Children’s Hospital, where I work, we did an in-depth study of kindergarten schoolchildren who receive vaccine exemptions across the country. Currently, 18 states allow nonmedical vaccine exemptions for either “conscientious objector” or “philosophical/personal belief” reasons. We were able to obtain information on 14 of those states.

A clear picture emerged: Vaccine exemptions are on the rise in 12 of the states we looked at. Indeed, anti-vaccine activities appear to be more of a western phenomenon, especially in the Pacific Northwest (Idaho, Oregon and Washington) and the American Southwest (Arizona, Missouri, Oklahoma, Texas and Utah).

What exactly is going on in the West, where many parents shun vaccines and take their children out of vaccination programs? Researchers are still at the early stages of understanding the reasons behind the anti-vaccine movement. A couple of these states, Oklahoma and Texas, host well-organized political action committees that lobby their legislatures and even raise campaign funds for candidates to endorse anti-vaccine positions. These committees appeal to parental fears of unwarranted government interference.

What’s more, some studies suggest that vaccine refusal is linked to affluence, and possibly with affluence there is greater access to the internet. There are now hundreds of anti-vaccine websites on the internet, many of which still allege that vaccines cause autism or that autism is a form of “vaccine injury,” neither of which is true.

Of course, scientists have proven the safety of vaccines over and over again. As the father of a daughter with autism, I have recently written “Vaccines Did Not Cause Rachel’s Autism.” My book details both how and why vaccines cannot cause autism based on the scientific literature, as well as the challenges my wife Ann and I face daily as parents and guardians of Rachel, now an adult living with significant intellectual disabilities.

However, my newest concern are the counties in the American West, where a high percentage of kids are being opted out of vaccination programs. I believe that these are the areas most vulnerable to terrible measles or pertussis outbreaks in the coming years. In the past year, Europe has been inundated with measles, including dozens of deaths, due to large declines in vaccine coverage. I’m concerned the U.S. could suffer a similar fate.
