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.

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.

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.
