Fact Checking an Anti-Vaccine Measles Outbreak Quiz

Anti-vaccine folks have gotten pretty good at pushing propaganda to keep you scared to vaccinate and protect your kids.

Now, they even have quizzes to help test how much of that misinformation you remember!

Fact Checking an Anti-Vaccine Measles Outbreak Quiz

A quiz about measles outbreaks by the ironically named Physicians for Informed Consent was recently promoted by Dr. Bob Sears.

How did Dr. Bob get 12 out of 12 correct if most of the answers are really wrong?

Let’s take a look at some of the questions and the anti-vaccine answers

There is only so much that better hygiene, sanitation, and nutrition can do, which is why about 400 to 500 people were dying of measles in the 1950s and early 1960s just before the first measles vaccines were developed.

While mortality rates did indeed decline for most diseases and conditions in the early part of the 20th century because of advancements in living conditions, nutrition, and health care, that effect had plateaued by the mid-1930s.

Being unvaccinated and unprotected is the main reason why people in underdeveloped countries die from measles, not low vitamin A…

It is true that vitamin A deficiency increases the risk for more severe complications and death from measles, which is why it can be more deadly in undeveloped countries where malnutrition is a big problem.

“Because of gaps in vaccination coverage, measles outbreaks occurred in all regions, while there were an estimated 110 000 deaths related to the disease.”

Measles cases spike globally due to gaps in vaccination coverage

Unfortunately, the other big problem in many of these countries is that these kids are unvaccinated because of a lack of access to vaccines.

This child doesn’t appear to have measles…

Immune globulin is a treatment option if you have been exposed to measles, but it is not actually a treatment once you have measles. And high dose vitamin A mainly benefits those with a vitamin A deficiency, which is unlikely in an industrial country, like the United States.

The only benefit of having measles, which you have to earn by having measles and surviving without complications, is that you will have developed immunity to measles.

In addition to having no other benefits, you will then be at risk for SSPE and may have wiped out your immune system for a few years.

While you are at risk for encephalitis and seizures after a natural infection, after getting a dose of MMR, one risk is a febrile seizure, which is typically thought to be benign.

The risk of having a febrile seizure after the first dose of the MMR vaccine is about 1 in 2,500 doses. There is also a small risk of having a febrile seizure if the flu vaccine is given at the same time as a Prevnar or DTaP vaccine.

It is important to note that vaccines are not the only reason that children have febrile seizures. Many infections, including vaccine preventable infections, can trigger febrile seizures, in addition to causing more serious types of non-febrile seizures.

This is not true.

It is very unlikely that any of the kids who develop febrile seizures after a vaccine will later develop epilepsy.

“Febrile seizures can be frightening, but nearly all children who have a febrile seizure recover quickly, are healthy afterwards, and do not have any permanent neurological damage. Febrile seizures do not make children more likely to develop epilepsy or any other seizure disorder.”

Febrile Seizures Following Childhood Vaccinations, Including Influenza Vaccination

Without any risk factors (parent or sibling with epilepsy, having complex febrile seizures, or abnormal development), a child with febrile seizures has the same risk of developing epilepsy has any other child.

Do anti-vaccine folks really read the inserts?

Like many other vaccines, the package insert for MMR does say that it has “has not been evaluated for carcinogenic or mutagenic potential, or potential to impair fertility.” That doesn’t mean that it hasn’t undergone safety studies for its potential to cause cancer, genetic mutations, and impaired fertility though.

Wait, what? Yeah, all vaccines have preclinical toxicology studies, including single and/or repeat dose, reproductive and developmental, mutagenicity, carcinogenicity, and safety pharmacology. If any issues are found, further studies are done.

The only way to think that a natural measles infection is safer than the MMR vaccine is if you believe that all reports to VAERS have been confirmed as being caused by the vaccine (they aren’t) and you don’t think about the fact that relatively few people get measles any more (so you don’t see or hear about many measles deaths) because most folks are vaccinated and protected!

How did you do on the quiz?

Did you easily spot all of the anti-vaccine propaganda?
