Who Gets SSPE?

Have you heard that you can get SSPE from the MMR?

Apparently it’s in the vaccine insert

Who Gets SSPE?

Subacute sclerosing panencephalitis (SSPE) occurs after a natural measles infection.

You won't get SSPE if you don't get measles.

It is not caused by MMR or any measles containing vaccine.

Of course, the measles vaccine is not 100% effective, so it is possible that you could still get measles after being vaccinated. And those folks who get measles after getting vaccinated could be at risk to get SSPE, but even then, their SSPE would be caused by wild measles virus, not a vaccine strain.

“Available epidemiological data are consistent with a directly protective effect of vaccine against SSPE mediated by preventing measles.”

Subacute sclerosing panencephalitis and measles vaccination

Again, SSPE is caused by natural measles infections and the wild type measles virus.

Tragically, after big outbreaks of measles, we start to see more cases of SSPE, with the greatest in children who get measles at a young age.

And SSPE is universally fatal in these children, who develop symptoms about six to eight years after recovering from having measles.

That the symptoms of SSPE don’t develop until long after you have recovered from measles is why the condition is often described as a time-bomb.

A time-bomb that you can’t stop.

Want to avoid getting SSPE? Get vaccinated and protected against measles.

Why You Have No Business Skipping the MMR Vaccine?

Believe it or not, some folks are still pushing misinformation to scare people away from getting vaccinated and protected against measles.

The Disney outbreak was not caused by a vaccine strain!
The Disney outbreak was not caused by a vaccine strain!

Ironically, this guy talks about propaganda, manipulating parents, and media lies without saying anything that is truthful.

As I’m sure you are aware, the Disney measles outbreak was not caused by a vaccine strain.

Anti-vaccine folks frequently misinterpret the meaning of these vaccine strain cases. They are people who were recently vaccinated and develop a fever and rash. They do not have measles and are not part of the outbreak counts.

The outbreak strain during the Disney outbreak was B3, which can be traced to outbreaks in Africa and the Eastern Mediterranean. Neither the Disneyland outbreak nor any outbreak has been caused by a vaccine strain of measles.

What about the idea that measles is now harmless???

Or that measles isn’t deadly is a developed country with a well-nourished population???

In response to a post praising Italy's decision to dilute their new vaccine laws, some folks thought it was funny that people were dying of measles.
Italy is a developed country with a very well-nourished population, and still, there have been at least 12 measles deaths since 2017.

Why have so many people died with measles in Europe recently if it is so harmless?

Yes, research it for yourself and you will find the complications of recent measles infections he left out, including the pregnant woman with who had a miscarriage during the 2013 measles outbreak in Brooklyn.

And the 8 SSPE deaths since 2009.

Are you wondering why he started his measles counts from 2014? It was to avoid mentioning the death of the woman in Washington in 2015.

Mostly remember that the reason we don’t see even more measles cases, measles complications, and measles deaths in the United States is simply because most people are vaccinated and protected.

Vaccines are safe, with few risks, and are obviously necessary.

Is the MMR Safe for 6-Month-Old Babies?

Most parents understand that the first dose of the MMR vaccine is routinely given to children when they are 12 to 15 months old, at least in the United States.

In some other countries, the first dose is routinely given as early as 8 to 9-months of age.

And in high-risk situations, the MMR can safely be given to infants as early as age 6-months.

Is the MMR Safe for 6 Month Old Babies?

An early MMR, is that safe?

This type of pure anti-vaccine propaganda is what caused the measles outbreaks in New York in the first place...
This type of pure anti-vaccine propaganda is what caused the measles outbreaks in New York in the first place…

Yes, it is safe.

What about the package insert?

“Local health authorities may recommend measles vaccination of infants between 6 to 12 months of age in outbreak situations. This population may fail to respond to the components of the vaccine. Safety and effectiveness of mumps and rubella vaccine in infants less than 12 months of age have not been established. The younger the infant, the lower the likelihood of seroconversion (see CLINICAL PHARMACOLOGY). Such infants should receive a second dose of M-M-R II between 12 to 15 months of age followed by revaccination at elementary school entry.”

MMR II Package Insert

The package insert says to give infants who get an early dose another dose when they are 12 to 15 months old! It doesn’t say to not protect these babies!

But what about the idea that the safety and effectiveness of MMR hasn’t been proven for infants under 12 months of age?

In general, the package insert is only going to list studies that the manufacturer used to get FDA approval for their vaccine. Since it is an off-label recommendation of the ACIP, they would not include the studies that show that an early MMR is safe and effective.

“In conclusion, this study indicated that the MMR was well tolerated and immunogenic against measles, mumps and rubella with schedule of first dose both at 8 months and 12 months age. Our findings strongly supported that two doses of MMR can be introduced by replacing the first dose of MR in current EPI with MMR at 8 months age and the second dose at 18 months in China.”

He et al on Similar immunogenicity of measles-mumps-rubella (MMR) vaccine administrated at 8 months versus 12 months age in children.

Before 8 months, an early MMR isn’t likely to be as effective as giving it later. That’s because some maternal antibodies might linger in a baby’s system and can interfere with the vaccine working, even after six months. How many antibodies and how much interference?

It’s almost impossible to tell for any one child, but the risk that this maternal protection has begun to wear off and these infants are at risk to develop measles is too great. That’s the reason that they get an early MMR, even though we know it won’t be as effective as a dose given later and we know it will have to be repeated.

Is this early dose safe?

“This review did not identify any major safety concerns. These findings may facilitate discussions about the risks and benefits of vaccinating infants who are potentially exposed to this life-threatening disease.”

Woo et al on Adverse Events After MMR or MMRV Vaccine in Infants Under Nine Months Old

Of course! Although the complications of measles can be serious, even deadly, we aren’t going to recommend something that is even worse.

“Early MMR vaccination is well tolerated, with the lowest AE frequencies found in infants aged 6-8 months. It is a safe intervention for protecting young infants against measles.”

van der Maas et al on Tolerability of Early Measles-Mumps-Rubella Vaccination in Infants Aged 6-14 Months During a Measles Outbreak in The Netherlands in 2013-2014.

So an early MMR is safe, with few risks, and is likely effective at preventing measles.

And by now you know what’s not safe. That’s right, getting measles.

Why Do We Include SSPE When Counting Measles Deaths?

Anti-vaccine folks often like to push the idea that parents shouldn’t worry about measles and that it is just a rash with a little fever.

They leave out the part that it is a week of having a high fever, irritability, and other symptoms too.

In addition to downplaying the symptoms of measles, they never talk about the possible complications, such as encephalitis, seizures, and death.

Why Do We Include SSPE When Counting Measles Deaths?

They certainly never talk about SSPE or subacute sclerosing panencephalitis.

“Subacute sclerosing panencephalitis (SSPE) is a progressive neurological disorder of children and young adults that affects the central nervous system (CNS). It is a slow, but persistent, viral infection caused by defective measles virus.”

Subacute Sclerosing Panencephalitis Information Page

SSPE is a late complication of having a natural measles infection.

That’s why it should be included when counting measles deaths.

“Available epidemiological data, in line with virus genotyping data, do not suggest that measles vaccine virus can cause SSPE. Furthermore, epidemiological data do not suggest that the administration of measles vaccine can accelerate the course of SSPE or trigger SSPE in an individual who would have developed the disease at a later time without immunization. Neither can the vaccine lead to the development of SSPE where it would not otherwise have occurred in a person who has already a benign persistent wild measles infection at the time of vaccination.”

Subacute sclerosing panencephalitis and measles vaccination

It is not a complication of having a measles containing vaccine. If it were, then why didn’t we see more cases of SSPE as more and more people got vaccinated, instead of a drop in SSPE cases and deaths, corresponding to a drop in measles cases?

But SSPE isn’t gone yet, just like measles hasn’t yet been eradicated.

32 of these SSPE deaths have been since 2000. Source is the CDC Wonder database.

Since 2000, when the endemic spread of measles was eliminated in the United States, there have been at least 37 SSPE deaths.

“Investigators learned that, in 2012, at age 11 years, the boy, who was previously healthy and developmentally normal, had been admitted to a tertiary care children’s hospital in Oregon with severe, progressive encephalopathy. Before the onset of his neurologic illness, the patient had been a straight-A, fifth-grade student who played soccer and basketball. The symptoms began approximately 4 months before the hospital admission, when the patient began to struggle with homework, drop utensils, and doze off during meals, eventually progressing to falling asleep while walking.”

Notes from the Field: Subacute Sclerosing Panencephalitis Death — Oregon, 2015

I say at least, because the CDC Wonder database doesn’t list the 2015 SSPE death of a boy in Oregon.

Anti-vaccine folks like to ignore the fact that yes, people have died of measles recently. And measles puts you at risk for SSPE, which is always fatal.

We are fortunate that no one has died since 2015, but as we get more and more measles cases, tragically, in addition of the risk of someone dying of measles directly, it increases the risk that someone will eventually develop SSPE.

“Decreasing rates of vaccination in the United States, particularly among preschool-aged children (children <5 years of age) living in inner-city areas, resulted in a resurgence in the number of cases of measles reported during 1989–1991; during this period, 55,622 cases of measles and 123 measles-associated deaths were reported.”

Bellini et al on Subacute Sclerosing Panencephalitis: More Cases of This Fatal Disease Are Prevented by Measles Immunization than Was Previously Recognized

Remember, there were at least 12 extra SSPE deaths following the large measles outbreaks of the late 1980s.

Will we see any after the rise in the cases the last few years?

Vaccines are safe, with few risks, and obviously necessary.

Don’t risk a complication of measles. Don’t risk getting SSPE.
