Did the AAP Say That Vaccines Cause Severe Brain Injury?

Bob Sears is telling folks that the American Academy of Pediatrics says severe brain injuries are caused by vaccines.

Bob Sears doesn’t mention that measles is much more likely to cause severe brain injury and death, or more recent studies that counter his post.

Did the AAP say that?

“A causal relationship they say.” Bob Sears

No, they didn’t.

The researchers in Pediatrics didn’t even say that…

Did the AAP Say That Vaccines Cause Severe Brain Injury?

What did they say?

“This clustering suggests that a causal relationship between measles vaccine and encephalopathy may exist as a rare complication of measles immunization.” Weibel et al on Acute Encephalopathy Followed by Permanent Brain Injury or Death Associated With Further Attenuated Measles Vaccines: A Review of Claims Submitted to the National Vaccine Injury Compensation Program

The study was about reports to VAERS…

Over 23 years, the researchers (in 1998) found reports of 48 cases of acute encephalopathy among about 75,000,000 children who were vaccinated, some clustered in the second week after they received a measles containing vaccine.

Does that mean that those measles containing vaccines caused the encephalopathy?

“In the absence of a specific test to determine vaccine causation, these 48 cases may include some nonvaccine cases representing background rates.” Weibel et al on Acute Encephalopathy Followed by Permanent Brain Injury or Death Associated With Further Attenuated Measles Vaccines: A Review of Claims Submitted to the National Vaccine Injury Compensation Program

No, it doesn’t.

It was a signal that got some attention though.

And as it has been further investigated, there has been no evidence that measles containing vaccines cause encephalitis, at least not above 1 in a million background rates.

What does cause encephalitis?

“About 1 child out of every 1,000 who get measles will develop encephalitis (swelling of the brain) that can lead to convulsions and can leave the child deaf or with intellectual disability.” Complications of Measles

Measles.

Measles, a life-threatening vaccine-preventable disease, causes encephalitis.

Are your kids vaccinated and protected with two doses of MMR?
