Politics trump science during GOP debate regarding vaccines
Children in the United States are at greater risk from preventable diseases today than they have been in decades, mostly because of misinformation about vaccines.
And when given a chance to spread truth and science during a presidential debate, three Republican candidates chose instead to add to the problem.
At issue: the decades-old, long-ago-debunked theory that vaccines cause autism.
It’s a myth. It’s no more true than the theory that the moon is made of cheese.
But that doesn’t keep a surprising number of people from spreading and believing misinformation about childhood vaccines.
Donald Trump is among those who has claimed vaccines cause autism. When asked about his statements during a debate featuring Republican candidates earlier this month, he backed off, but only a little, and then he tried to edge back, using an anecdote that seemed to indicate that he indeed did think vaccines caused autism.
The moderators then turned to candidates Ben Carson and Rand Paul, both of whom are medical doctors. And while both stated that they believed vaccines were safe and the research solid, they went on to hint that, well, maybe there was cause to be concerned. And Carson pointed to the number of vaccines administered during what he considered a short amount of time.
A fourth candidate also weighed in. Candidate Mike Huckabee noted there’s controversy about the subject.
Well of course there is controversy, because people such as Huckabee, Paul, Carson and Trump prefer politics over science.
And the science is clear. It has been for more than a decade. I’m not sure how many times it has to be said: Vaccines do not cause autism.
The timing of vaccines isn’t a medical concern either, according to the research. Pediatric experts note that earlier vaccines mean earlier protection for children.
Those who continue to espouse mythical dangers of vaccines are turning their backs on established medicine and legitimate research.
Either that, or they make the common mistake of confusing “correlation” with “causation.”
There is a correlation between young children receiving vaccines and young children being diagnosed with autism. But that doesn’t mean one causes the other.
You don’t have to go far to understand why “correlation” can’t be used to presume a cause and effect.
Let’s say we apply the “link” Trump sees to a study by a consulting firm that examined the kinds of alcoholic beverages Americans drink.
As reported by the Washington Post, what the data from the firm GFK MRI – and analyzed by Jennifer Dube of National Media Research Planning and Placement – found is that there is a correlation between people’s political views and what kinds of alcoholic beverages they drink.
Bourbon drinkers tend to be conservative, for example, while those who drink vodka tend to be liberals, according to the data.
Now, no one claims that bourbon makes a person conservative, or that drinking vodka inspires liberal beliefs.
Similarly, it is true that most young children get vaccines. It’s also true that autism is often first suspected or diagnosed in young children. However, that doesn’t mean that one causes the other.
On the autism front, researchers recently have found surprising correlations between parents’ ages and the tendency for autism. Rates of autism rise when parents are older, and also when there is a gap between the ages of the father and the mother.
Scientists don’t pretend to know why this link exists. They stress that what they have at this point is a correlation, one that may mean nothing.
That is what makes them different from politicians, conspiracy theorists, bad-science enthusiasts and others who go looking for a cause-and-effect and cling to it even after the facts have proved them wrong.
Since the anti-vaccine crowd gained traction, especially in celebrity circles, vaccination rates in many states, including Kansas, have started to fall.
Falling vaccine rates create risks that are not theoretical. More children are suffering from measles, whooping cough and other preventable diseases, and more of them are dying.
Right now, it’s not a big number. For example, there were more than 48,000 cases and 20 deaths from whooping cough (or pertussis) in 2012, according to the Centers for Disease Control. That’s not many, but there were more cases in 2012 than in any year since 1955, according to the CDC.
Unless vaccination rates head back in the right direction, more children will be left unprotected, and that makes outbreaks of disease more likely.
The outbreak of measles that was traced last December to Disneyland in California provides an example of how quickly and how far a contagious disease can spread.
Despite quick action by authorities, by the end of January, more than 80 people in 14 states had gotten sick. By the time medical professionals brought the outbreak to an end in the spring, nearly 200 people in 24 states had gotten sick.
This year also saw the first death from measles in the United States in 12 years.
Americans have never been very discerning when it comes to health claims. We have a long history of quacks and quackery that continues into the 21st century.
But we should be able to count on those who would lead the country to base their health policies on science, not debunked research and specious theories.
