Were 38% of the Disneyland Measles Cases a Vaccine Strain?

Why do some people think that 38% of the Disneyland measles cases were caused by a vaccine strain of measles?

There were no vaccine strain measles cases in the Disneyland outbreak.
There were no vaccine strain measles cases in the Disneyland outbreak.

Maybe because anti-vaccine folks have been pushing this propaganda for years now…

Were 38% of the Disneyland Measles Cases a Vaccine Strain?

Jim Meehan wasn’t the first to make the claim.

Kenneth Stoller made the claim as part of his factual background and under “penalties of perjury” when he was being investigated for writing fraudulent medical exemptions in California.

There were no vaccine strain measles cases in the Disneyland outbreak.

And it has been repeated over and over again.

There were no vaccine strain measles cases in the Disneyland outbreak.

And not just about California.

There were no vaccine strain measles cases in the Disneyland outbreak.

Larry Palevsky seems to think that the big outbreaks in New York could have just been folks with vaccine-strain measles…

“All measles cases this year have been caused by measles wild-type D8 or B3.”

Of course, none of this is true.

There were no vaccine strain measles cases in the Disneyland outbreak.

There were no vaccine strain measles cases in the Disneyland outbreak!

What the California Department of Public Health reported were recently vaccinated persons who developed a febrile rash, which is a common side effect of the MMR vaccine. They were tested because they were in the middle of a measles outbreak and they wanted to make sure that these folks didn’t have measles. And they didn’t.

A few studies even describe the methods they used.

“Here, we describe a real-time reverse transcription-PCR (RT-PCR) method that detects the vaccine genotype (MeVA RT-quantitative PCR [RT-qPCR]) and that can provide rapid discrimination between wild-type-virus infections and vaccine reactions.”

Again, the “vaccine reaction” is not that they developed measles! They developed a rash and/or fever, a common side effect of the MMR vaccine.

So how do we know that most cases in other outbreaks aren’t recently vaccinated persons with a febrile rash illness?

“During outbreaks, measles vaccine is administered to help control the outbreak, and in these situations, vaccine reactions may be mistakenly classified as measles cases.”

Well for one thing, most of the cases are in folks who aren’t vaccinated!

And measles symptoms are much more severe than the few days of fever and rash that you might get after being vaccinated.

But if necessary, testing can be done to see if it is a vaccine strain and to see if they don’t actually have measles.

And can everyone now stop saying that that 38% of the Disneyland measles cases were caused by a vaccine strain of measles?

  1. Lol, you guys make me laugh.

    The goal with this vaccine is to deliberately infect a child with measles so that they gain immunity.

    This is done by injecting a *live virus* into the child. It’s attenuated but it’s still a live, infectious agent that must infect the child sufficiently or the body won’t produce the necessary antibodies.

    Then we observe a rash (the expected response from an infection), perform a PCR test, see that it’s genotype A and somehow it’s no longer what it obviously is: a measles infection.

    Good thing people are waking up to the shell game you folks are playing.
