Polio Wasn’t Vanquished, It Was Redefined

Perhaps the most egregious example of clever sleight of hand (… not to mention the outright, blatant rewriting of history) on the part of public health officials in the United States occurred in 1954 when the U.S. government changed the diagnostic criteria for polio.1 It was the year that medical researcher and virologist Jonas Salk produced his inactivated injectable polio vaccine ((IPV). The vaccine was licensed in 1955 and began to be used to inoculate millions of children against polio.

The Salk vaccine has been widely hailed as the vanquisher of polio, and it is commonly used as the shining example of how vaccines are the miracle drugs for combating infectious diseases… and now even against diseases that are not infectious. Pick any disease, illness or disorder you want. You got cancer, cholera, peanut allergies, stress, obesity… we’ll develop a vaccine for it.

What the apologists for the Salk vaccine regurgitate from a common script (… some might say scripture) is that before the vaccine was introduced and tested on one million children—the so-called “Polio Pioneers”—in 19542 more than 50,000 people in the U.S. were contracting polio each year, and that by the end of the 1950s the numbers were down to less than 10,000.3 Ergo, the Salk vaccine saved the U.S. from polio. Open and shut case.

Hmm, not so fast.

What is conveniently omitted from this heroic story is that the reason the number of polio cases in the U.S. dropped so precipitously following the mass introduction of the Salk vaccine in 1955 was not medical, but rather administrative. Yes it’s true, in 1952 there were 52,879 reported cases of polio in the U.S. And yes, in 1955 the number went down to 28,985, and by 1959 it had dropped to 8,425.3 But first of all, it’s important to note that the numbers were already declining significantly prior to the initial use of the Salk vaccine. In 1953, there were 35,592 cases of polio in the U.S.3 So there were other things going on in the U.S. at the time totally unrelated to the Salk vaccine.

More importantly, though, in 1954 the U.S. government simply redefined polio. Yes, the government can do that. It does this kind of stuff occasionally in order to help it meet its public policy objectives when it is unable to actually achieve them. How often have you heard of Congress playing smoke and mirrors, gimmicks with the national budget deficit, or on the issue of the unemployment rate? Exactly.

When it comes to government and public policy, the truth is seldom absolute. That’s just the nature of the beast.

According to Dr. Bernard Greenberg, head of the Department of Biostatistics of the University of North Carolina School of Public Health:

In order to qualify for classification as paralytic poliomyelitis, the patient had to exhibit paralytic symptoms for at least 60 days after the onset of the disease. Prior to 1954, the patient had to exhibit paralytic symptoms for only 24 hours. Laboratory confirmation and the presence of residual paralysis were not required. After 1954, residual paralysis was determined 10 to 20 days and again 50 to 70 days after the onset of the disease. This change in definition meant that in 1955 we started reporting a new disease, namely, paralytic poliomyelitis with a longer lasting paralysis.1

As I wrote in my piece “The Salk ‘Miracle’ Myth“…

Under the new definition of polio, thousands of cases which would have previously been counted as polio would no longer be counted as polio. The change in the definition laid the groundwork for creating the impression that the Salk vaccine was effective.4

So as radio broadcaster Paul Harvey used to say for decades at the close of each of his charming commentaries, “And now you know… the rest of the story.”

    What utter rubbish I was one of there at one of the last outbreaks. I saw by the end of 6 weeks 5 empty desks 2 to never return because of death 1 for paralyalsis and 1 with leg irons the other with a withered hand and that was with the new Russian oral vaccine being brought in early. Reality Polio kills and maims and on that basis some 15% of the young population as there was 33 in the class. If you want to risk that on your kids carry on but please make the decision on the truth and remember I WAS THERE.
