Why Do Anti-Vax Folks Get Excited About Polio Outbreaks?

At least two things happen whenever we hear about a new polio outbreak. And yes, I said polio outbreak.

One is that many people assume it is wild polio and that we are moving further away from finally eradicating polio.

Hopefully folks understand that polio outbreaks wouldn't just stop if we stopped vaccinating...
Hopefully folks understand that polio outbreaks wouldn’t just stop if we stopped vaccinating…

And the other?

Anti-vax folks assume that it is an outbreak of vaccine strain polio and very wrongly use this as a reason to try and scare parents away from vaccinating and protecting their kids.

“The polio outbreak in the Philippines is confirmed to be from a circulating vaccine-derived poliovirus type 2. This is of particular concern, as wild poliovirus type 2 was certified as globally eradicated in 2015. Poorly conducted immunization activities, when too few children have received the required three doses of polio vaccine, leave them susceptible to poliovirus, either from vaccine-derived or wild polioviruses. Full immunization protects them from both forms of the virus.”

As expected, that’s the response we are seeing from anti-vax folks to news of the latest outbreak of polio in the Philippines.

Why Do Anti-Vax Folks Get Excited About Polio Outbreaks?

But isn’t bad that the polio vaccine can actually cause outbreaks?

Of course!

No one wants people to get sick after getting vaccinated. And that’s why we are moving towards stopping the use of the oral polio vaccine that causes vaccine derived polio.

It is also very important to consider the alternative. A lot more people getting wild polio!

“As recently as 30 years ago, wild poliovirus paralysed more than 350,000 children in more than 125 countries every year. In 2018 there were fewer than 30 reported cases in just two countries – Afghanistan and Pakistan.”

“Zero polio transmission and health for all”, WHO Director-General gives new year’s wish to the people of Afghanistan and Pakistan

We also need to remember the reason we typically see outbreaks of vaccine strain polio. It is because vaccination rates have dropped in an area!

Wait, what?

Yes, that’s right. The polio vaccine, in addition to protecting you from wild polio can prevent you from getting the vaccine strain polio too.

But isn’t the polio vaccine causing many more cases of polio than the actual polio virus?

Bob Sears recently shared an article that was two years old about mutant strains of polio causing outbreaks

It once was, but that’s simply because we are getting very close to eradicating polio and there were fewer cases of wild polio!

While there were far more cases of vaccine derived polio than wild polio last year, there were more cases of wild polio earlier in 2019 and it is now about even.

Tragically, we are starting to see more and more cases of wild polio.

Still, we are no where near the numbers of cases of polio and kids getting paralyzed when polio was epidemic in most countries.

And the outbreaks of vaccine derived polio?

They demonstrate what happens when we don’t keep up our immunization rates. And how anti-vax folks either don’t understand or intentionally try to misinform parents about how vaccines work.

Are Mutant Strains of Polio Vaccine Now Causing More Paralysis Than Wild Polio?

Believe it or not, it’s true.

Mutant strains of polio vaccine have been causing more paralysis than wild polio.

Are Mutant Strains of Polio Vaccine Now Causing More Paralysis Than Wild Polio?

Although anti-vaccine folks seem to be having a field day over the news, it doesn’t really mean what they think it means.

It isn’t even true anymore…

Not getting polio is a good thing. A pediatrician, especially one who wrote a vaccine book should understand the benefits of the polio vaccine.

The article Bob Sears shared isn’t even current…

“So far in 2017, there have been only six cases of “wild” polio reported anywhere in the world. By “wild,” public health officials mean the disease caused by polio virus found naturally in the environment.

By contrast, there have been 21 cases of vaccine-derived polio this year.”

Mutant Strains Of Polio Vaccine Now Cause More Paralysis Than Wild Polio

It was from two years ago.

There were only 22 cases of wild polio in the world in 2017. We are on track for many more cases this year.

He doesn’t even mention the main reason that mutant strains of polio vaccine are now causing more paralysis than wild polio.

“Global efforts to immunise children with the oral polio vaccine (OPV) have reduced wild poliovirus cases by 99.9% since 1988.”

Fact Sheet: Vaccine-Derived Poliovirus

And that is simply because most people are vaccinated and protected and we are very close to eradicating polio!

“As recently as 30 years ago, wild poliovirus paralysed more than 350,000 children in more than 125 countries every year. In 2018 there were fewer than 30 reported cases in just two countries – Afghanistan and Pakistan.”

“Zero polio transmission and health for all”, WHO Director-General gives new year’s wish to the people of Afghanistan and Pakistan

Nor does he mention that vaccine derived polio virus strains mutate when too many people are unvaccinated.

What else does Bob Sears leave out of his post?

Polio this week as of 24 July 2019, with more paralysis from wild polio viruses than mutant strains of the polio vaccine.
Polio this week as of 24 July 2019, with more paralysis from wild polio viruses than mutant strains of the polio vaccine.

So far, this year, we are tragically seeing more paralysis from wild polio than mutant strains of the polio vaccine!

What’s the last thing Bob Sears left out of his post?

Most of the “mutant strains” of polio vaccine are from the type 2 vaccine virus, which isn’t being used anymore. In 2016, all countries switched to bivalent OPV, which doesn’t include the type 2 polio virus strain.

And since most cases of wild polio are in just a few countries, namely Pakistan and Afghanistan, we will hopefully get back on track to eradication and also see a drop in paralysis from the mutant vaccine strains. That’s when we can stop using the oral polio vaccine all together.

At least we will if folks stop listening to anti-vaccine misinformation and propaganda that scares them away from vaccinating and protecting their kids.

Alternative Names for Vaccine Preventable Diseases

You know all of the names – measles, mumps, rubella, diphtheria, whooping cough, etc.

But do you know why they used to call 10-day measles?

And which disease causes a 100-day cough?

Alternative Names for Vaccine Preventable Diseases

Back in the day, when these diseases were more common, they used much more descriptive terms and nicknames, in addition to their official names.

Why was measles known as 10-day measles?

Because there was also a 3-day measles!

MeaslesRubella
10-day measles3-day measles
red measlesGerman measles
rubeola

Unfortunately, 10-day measles made you feel miserable for 10 days!

Although a vaccine was available, it took a little more time to get measles under better control.

Can you guess which disease was known to cause a 100-day cough?

That’s right, it’s whooping cough or pertussis.

“I honestly felt like it was never going to go away. The doctor told me it was 100 day cough, so I was counting the days while Googling to see if there was anything that could help. I tried everything, you name it, I tried it, and nothing worked. It came to 120 days and I couldn’t understand why it wasn’t gone. I then researched and found that babies take longer to get over whooping cough.”

Fern’s Story – Whooping Cough

Fortunately, the cough doesn’t typically last that long if you are vaccinated and still get pertussis.

What do they call rabies?

Mad dog disease.

But that’s an easy one.

Which disease was known as “the Strangling Angel?”

“The breathing became much more difficult, with a kind of rattling stertor, as if the patient was actually strangling, the voice being exceeding hoarse and hollow, exactly resembling that from venereal ulcers in the fauces. This noise, in speaking and breathing, was so peculiar, that any person in the least conversant with the disease might easily know it by this odd noise; from whence, indeed, the Spanish physicians gave it the name of garrotillo, expressing the noise such make as are strangling with a rope.”

Edward Headlam Greenhow on Diphtheria

How about “The Crippler?”

Polio, also known as infantile paralysis, was known as “The Crippler.”

Even mild smallpox, as depicted on this WHO Smallpox Recognition Card, included flu like symptoms, a few weeks of pustules, and then waiting for the lesions to scab over…

We forget these names, because we don’t see these diseases anymore.

“…for those trained in pediatrics in the 1970s, Hib (Haemophilus influenzae type b) was a horror.”

Walter Orenstein

Do you remember that measles was called a “harmless killer?”

Be sure to think about how these now vaccine-preventable diseases got their nicknames before you think about skipping or delaying your child’s vaccines.

Have Normal Childhood Diseases Become More Deadly?

Weren’t measles and chicken pox once a rite of passage for kids?

Yes, in the pre-vaccine era, almost all kids got measles, chicken pox, and other now vaccine-preventable diseases in early childhood.

It was considered a rite of passage.

That she doesn't understand survivorship bias doesn't mean that you shouldn't vaccinate your kids.

But these diseases were never benign.

They were considered a rite of passage only because we all had to endure them. They weren’t something anyone looked forward to.

After all, you don’t typically die from a benign disease.

Have Normal Childhood Diseases Become More Deadly?

But what about the idea that folks never used to worry about these diseases, at least not until vaccines were developed? Or that we only fear diseases that are vaccine-preventable?

It’s easy to say that no one worried about measles in the pre-vaccine era when you are just trying to scare folks away from getting vaccinated.

That’s one of the more ridiculous arguments anti-vaccine folks make.

A measles epidemic hit New York City in 1951, as this front page NYTimes article reports.
A measles epidemic hit New York City in 1951 and made headlines in the New York Times. That’s not surprising, as there were 683 measles deaths in the United States that year.

And also one of the easiest to refute.

When was the last time that you saw a headline warning about congenital rubella syndrome?

These diseases that are now vaccine-preventable routinely made headlines in the pre-vaccine era.

Even the schools were closed in San Antonio when polio came to Texas in 1946.
Even the schools were closed in San Antonio when polio came to Texas in 1946.

And it was surviving these diseases that was considered a rite of passage, at least for those who were fortunate enough to survive.

So no, childhood diseases have not become deadlier.

They have always been serious and life-threatening!

Of course, not everyone died who got them, but they were rarely a walk in the park. Remember, even a mild case of measles includes a high fever for 4 to 7 days. That’s why folks often end up seeking medical attention multiple times, even if they don’t end up having any complications and don’t need to get admitted to the hospital

Lassie got shot, but ended up saving the day, getting help for Timmy, after they ran out of gas taking a short cut rushing home.
The Lassie episode about measles, in 1958, was called ‘The Crisis.” There were 552 measles deaths in the United States that year.

But what about the Brady Bunch measles episode, Is There a Doctor in the House? Is that really why you think vaccine-preventable diseases are mild?

In 1969, when that episode first aired, there were 25,826 reported cases and 41 deaths from measles in the United States.

Why don’t we see that many deaths now?

That’s easy.

We don’t see as much measles now. Most folks are vaccinated and protected.

If more people skip or delay their vaccines though, we will see more and more outbreaks, with greater chances that people will die.

Believe it or not, we still don’t have cures for measles, chicken pox, congenital rubella syndrome, and hepatitis B, etc. So while these diseases haven’t become any more deadly, they haven’t become any less deadly either, even with all of the advances of modern medicine.
