Measles prevents cancer? Another anti-vaccine myth with no evidence

Darla Shine, a former Fox News producer, and wife of the White House deputy chief of staff of communications, of course, posted a dangerous and ignorant tweet that implied that measles prevents cancer.

Shinee is repeating a thoroughly debunked anti-vaccine religious trope, but what do you expect from a Trump sycophant? The truth? Especially since Trump has a history of anti-vaccine rhetoric.

Of course, there is a reason why this myth has legs, but it’s not based on what we call robust evidence – it’s based on pseudoscience, misinformation, and nonsense.

Why do the anti-vaxxers think that measles prevents cancer?

As I’ve written dozens of times, anti-vaxxers look for anything that supports their predetermined conclusion – that’s one of the signs of pseudoscience. Real science develops conclusions based on ALL of the evidence that derives from the scientific method.

I have no personal investment as to whether vaccines are safe and effective, although I am thrilled that they are. My only concern is what the evidence tells me, and it’s overwhelming – vaccines are safe and effective.

On the other hand, the anti-vaxxers want to believe something, anything, that will “prove” that vaccines are not safe, not effective, or not useful for health. Thus, they promote measles prevents cancer trope. 

Before we start, here’s a big hint. If anyone says that they have the miracle prevention or miracle cure to cancer, then stop, take a deep breath, and laugh. Laugh very loud and very.

Cancer is not one disease, it is 200, probably a lot more, different diseases with different etiologies, different pathophysiologies, different treatments, and different outcomes. There’s really no similarity between cancers except for the phenotype – excessive and uncontrolled growth of cells. There never will be one cure to cure them all. 

This strange belief is based on a “study” published 20 years ago in the Medical Hypotheses,  which at that time was not peer-reviewed. The journal was well known as a garbage dump for whacky ideas in medical science like HIV-AIDS denialism. Furthermore, the “research” was performed by anthroposophic doctors in Switzerland. 

Furthermore, the study wasn’t a high-quality case-control or retrospective cohort study. It was a questionnaire, which is subject to massive confirmation and observation biases along with memory issues. This type of study is considered quite low on the hierarchy of biomedical research.

Anthroposophic medicine is an alternative medicine that utilizes occult ideas to make it appear they have something more than science-based medicine. Dr. David Gorski, who addressed the appearance of this junk medicine at his alma mater, the University of Michigan Medical School, made a key observation about this pseudoscience:

  • Many illnesses, especially benign ones, should not be artificially prevented, but should be allowed to occur and be treated and healed. The patient thereby gains strength and experience, both biologically and spiritually. [This would appear to be the basis for so many anti-vaccine beliefs that permeate every aspect of anthroposophic medicine and the education taught in Waldorf schools. After all, what is vaccination, but preventing illness? I guess your kids get so much stronger, spiritually and biologically, if you just let them, take their chances with measles, mumps, whooping cough, and Haemophilus influenzae type B. Because, you know, that worked out so well for children in terms of childhood mortality back in the days before vaccines could prevent these diseases. Oh, wait. No it didn’t.]

Maybe it’s not obvious to everyone, but it is to me. Of course, an anthroposophic doctor would think that getting a measles infection would prevent cancer because that fits into their bias about their view of medicine.

However, let’s put it this way – if someone had real evidence that a measles infection reduced the risk of any of the 200 or more different cancers, then it would be published in any of 100s of highly respected journals with that research repeated over time. And there would be hundreds of articles discussing how measles prevents cancer. But that hasn’t happened.

What does science say about measles prevents cancer?

Well, science does say something, but not quite in the way the anti-vaccine radicals would want you to think. In fact, there is a growing body of evidence that a measles infection could be linked to some cancers:

Are any of these studies convincing? Not really, but they are intriguing. And they are much more powerful (and published in highly respected journals) than the garbage study published by the anthroposophic doctors. 

Since I’m a real scientist I’m not going to say that the measles vaccine will prevent cancer. But I could if I followed the same ethical standards as the anti-vaccine crackpots like the Trump lackey, Darla Shine. 

Of course, there are vaccines that do prevent cancer. The HPV and hepatitis B vaccines certainly prevent cancer. 

There are a couple of other research studies that may have contributed to the anti-vaccine nonsense that measles prevents cancer. Some scientists have developed a method to carry molecules that kill cancer cells to those cancer cells with an engineered measles virus, but that’s not what circulates in the wild. It’s altered to do a specific job.

And there is an ongoing clinical research effort where another bioengineered measles virus, again not the wild type virus, may be useful in treating some types of cancer. 

Let me repeat myself, just in case it’s not clear. Neither of these measles viruses is what your children (or yourself) would encounter circulating in the current measles outbreaks. They are measles viruses that are genetically engineered to do a very specific job – kill cancer cells.

Let’s remember what measles does

On the other hand, measles does actually cause some serious complications:

  • death
  • hospitalization
  • encephalitis
  • SSPE
  • pneumonia
  • seizures

And the MMR vaccine prevents all of these complications. 


Donald Trump minion, Darla Shine, passed along a solid lie about the measles. Getting the virus does not prevent cancer unless you accept the results of a bunch of pseudoscience-pushers who put together a garbage study then published it in a garbage non-peer-reviewed garbage journal.  

There is no robust, repeated, high-quality evidence that has ever shown a causal link between measles infection and preventing cancer. None.

In fact, there is some weak evidence that measles infection is linked to certain cancers – a link that, along with the known serious complications of measles, should be enough to make parents reconsider any thought that measles is some harmless disease. It is not. 

Measles is a dangerous and deadly disease. And the measles vaccines prevents that.
