That Time Del Bigtree Admitted He Manipulates Folks and Their Fears of Vaccines
It seems that we got an answer this week with a new edition of Fault Lines, The Viral Threat: Measles and Misinformation.
Our latest @AJFaultLines delves into the debate over vaccines. In this clip I sat down with one of the leading voices in the anti-vax movement, Del Bigtree. This is 2 mins of what was a long & difficult discussion. Find a link to the whole episode pinned at the top of my feed. pic.twitter.com/gxTb59iDM1
He knows that when he talks about 400 reported vaccine deaths on his show, it doesn’t really mean that 400 people died from vaccine injuries. He knows that they aren’t confirmed vaccine deaths, even though he never says that on his show.
John Rushing: The numbers the way you’re using them though, it implicitly warns against using them that way.
Del Bigtree: Yeah. Yes.
John Rushing: You’re saying that there are 412 deaths last year.
Del Bigtree: I – no. What I’m saying is there’s 412 reported deaths. I never said there were 412 confirmed deaths reported.
John Rushing: So, so some of those causes of death on VAERS
Del Bigtree: Yeah.
John Rushing: one was a drowning.
Del Bigtree: Sure.
John Rushing: One was from co-sleeping. One was from a pre-existing heart condition. There’s no – because a death is reported in VAERS – there’s no way to show causation to the vaccine.
Del Bigtree: Okay.
John Rushing: But in watching your speech and watching your show – man, you would come away thinking 400 people died from vaccines last year.
Del Bigtree: Okay.
John Rushing: And then I can start to see
Del Bigtree: Okay.
John Rushing: where they get the number. And then I go to the source and the source says “don’t use the number that way.”
Most parents understand that vaccines are safe, with few risks, and necessary, but some are still scared to get their kids vaccinated and protected.
Some even get anxious at the idea of going to their next visit to their pediatrician, because it might mean their baby is going to get shots.
They have likely heard some of those vaccine injury stories and got to thinking – how could all of those parents be wrong?
Mistaking Subsequence for Consequence
It’s easy to make a hasty judgement about something.
We jump to conclusions and try to link things together when they occur at about the same time as each other.
That’s because we often mistake subsequence (the state of following something) for consequence (a result of an action).
For example, developing multiple sclerosis (the consequence) six weeks after (subsequent) getting a vaccine, doesn’t mean that the vaccine caused you to develop multiple sclerosis.
Although the source of the quote on subsequence and consequence is Dr. Samuel Johnson, an 18th century writer, it got new life when Justice Jeremy Stuart-Smith used it in a DTP vaccine trial verdict.
“Where given effects, such as serious neurological disease or permanent brain damage, occur with or without pertussis vaccination, it is only possible to assess whether the vaccine is a cause, or more precisely a risk factor, when the background incidence of the disease is taken into account. The question therefore is, does the effect occur more often after pertussis vaccination than could be expected by chance?”
Instead of thinking that things could simply be the result of chance or a coincidence, we typically want more of an explanation when something happens, and sometimes, we simply want someone or something to blame.
“Establishing or disproving cause and effect, particularly for events of major consequence, proved difficult. Although the original allegations of causation were largely anecdotal and based on the fallacious assumption that subsequences and consequences were synonymous, they raised great concern and stimulated the search for an improved vaccine.”
Vaccines (Seventh Edition)
That leads us to fallacious thinking – post hoc ergo propter hoc (after this, therefore, because of this).
It shouldn’t though.
“Most of you will have heard the maxim “correlation does not imply causation.” Just because two variables have a statistical relationship with each other does not mean that one is responsible for the other. For instance, ice cream sales and forest fires are correlated because both occur more often in the summer heat. But there is no causation; you don’t light a patch of the Montana brush on fire when you buy a pint of Haagan-Dazs.”
Remember, “correlation does not imply causation.”
That maxim becomes easier to understand when you see all of the things that correlate together, like ice cream sales and forest fires, but once you think about them, there is no way that one could cause the other.

“It is incident to physicians, I am afraid, beyond all other men, to mistake subsequence for consequence.”
Dr Samuel Johnson
Fortunately, it is not as “incident to” (likely to happen to) physicians these days to “mistake subsequence for consequence.”
There are certainly some vaccine friendly pediatricians who pander to the fears of parents and push so-called alternative, non-standard, parent-selected, delayed protection vaccine schedules, who seem to believe in anecdotal evidence above all else, but most doctors understand that vaccines are safe and necessary.
They also know that because correlation can sometimes equal causation, we don’t ignore possible vaccine injuries. And that’s why we have strong vaccine safety systems that can detect and warn us of true vaccine risks.
“…the measles outbreak was made out to be a unfounded panic created by big pharmaceutical companies and meant to push legislative agendas. Del Bigtree, a celebrity in the anti-vaccine movement, spoke with “Dr. Bob Sears.” My mom and I sat down, watching this video so she could prove her beliefs were not unfounded. In this video, Dr. Bob Sears claims that in the past 15 years there hasn’t been a single death to the measles. In contrast, 449 people have had fatal reactions to the MMR vaccine.”
Testimony of Ethan Lindenberger Student at Norwalk High school Before the Senate Health, Education, Labor, and Pensions Committee March 5th, 2019
These and many other comments didn’t make it into his oral statements.
“Although Ethan did not include this information in his verbal testimony, it was part of his original verbal statements (which were leaked), then edited out – for obvious reasons.”
The obvious reason is that each witness only had five minutes to speak, not some conspiracy as Dr. Bob seems to be implying!
And his original, written statements weren’t leaked. Like the statements of every other witness, they were posted on the Senate Committee website.
After clearing up all of that, do we still need to discuss how Dr. Bob is trying to justify any of his statements about the MMR vaccine?
Even though you can guess where this is going, let’s go ahead and do it to be complete, especially since Dr. Bob really does seem to want folks to know where “the fact” of the 459 fatal reactions to the MMR vaccine come from.
You likely already know this, but they are simply reports to VAERS. And you likely also know that “inclusion of events in VAERS data does not imply causality.” That little fact is included in a disclaimer when you search the VAERS database, which is why anti-vaccine folks created their own search tool at MedAlerts – the reference Dr. Bob uses.
But just because we understand that these reports aren’t proof of causality doesn’t mean that we dismiss them. No one dismisses VAERS reports as unscientific, as Bob Sears claims.
“And if you are the type of doctor, or Legislator, who likes to dismiss VAERS reports as “unscientific,” then please explain why HHS even bothers to collect the data? Spend millions of dollars collecting scientific data, then do nothing with it? Who does that? And what type of scientist ignores data? Is that what Congress had in mind when it created the VAERS system as a Federal Law?”
“VAERS is used to detect possible safety problems – called “signals” – that may be related to vaccination. If a vaccine safety signal is identified through VAERS, scientists may conduct further studies to find out if the signal represents an actual risk.”
CDC on How VAERS is Used
Remember, it was using VAERS data that CDC and FDA vaccine experts quickly discovered that the first RotaShield rotavirus vaccine was associated with an increased risk of intussusception.
“In addition, the American Academy of Pediatrics warned about this in a 1998 publication in Pediatrics that confirmed 48 cases of severe or fatal encephalopathy after Measles Vaccination in the 70s and 80s: 8 children died, and the rest survived but were neurologically devastated.”
What about the AAP warning about encephalopathy and the measles vaccine?
Dr. Bob is talking about a 1997 paper, 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, which concluded that “this clustering suggests that a causal relationship between measles vaccine and encephalopathy may exist as a rare complication of measles immunization.”
“Nevertheless, with a denominator of 75,000,000 vaccinees throughout 23 years, the incidence of acute encephalopathy caused by measles vaccine in this cohort can reasonably be described as very low.”
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
Bob left that part out, didn’t he?
Considering how many children used to die and develop measles encephalitis each year, this small risk would still seem to greatly outweigh the risk of remaining unvaccinated and at risk to get measles.
Fortunately, even that risk is something we likely don’t have to worry about!
“We did not identify any association between MMR vaccination and encephalitis, aseptic meningitis, or autism.”
Mäkelä et al on Neurologic disorders after measles-mumps-rubella vaccination.
Although encephalopathy or encephalitis is still a table injury, studies have shown it is likely not associated with getting the MMR vaccine.
“For encephalitis and aseptic meningitis, the numbers of events observed within a 3-month risk interval after vaccination were compared with the expected numbers estimated on the basis of occurrence of encephalitis and aseptic meningitis during the subsequent 3-month intervals. “
Mäkelä et al on Neurologic disorders after measles-mumps-rubella vaccination.
And then there is the 2012 IOM report, Adverse Effects of Vaccines: Evidence and Causality, which found inadequate evidence to be able to conclude that encephalitis was caused by vaccines.
“The last child to die from measles infection in the United States was back in 2003. Since then, over 100 fatal VAERS reports have been filed for the MMR vaccine. At what point would mandating this no longer be considered in the interest of the greater good? “
Bob ignores those reports and ignores the fact that a woman died in 2015.
He also ignores the fact that you don’t even have to go all of the way back to 2003 to find the last child who died of measles.
a 17-year-old died of SSPE in 2004
a 1-year-old died of measles in 2005
an 11-year-old died of SSPE in 2005
an 8-year-old and a 12-year-old died of SSPE in 2006
a 19-year-old died of SSPE in 2007
a 13-year-old died of SSPE in 2008
a 17-year-old died of SSPE in 2011
an infant died of SSPE in 2012
More importantly though, he ignores that fact that the only reason that there aren’t even more measles deaths these days is because most people are vaccinated and protected! Even Bob used to understand this…
“I also warn them not to share their fears with their neighbors, because if too many people avoid the MMR, we’ll likely see the diseases increase significantly.”
Bob Sears in The Vaccine Book
Unfortunately, people shared their fears with their neighbors… And we are seeing the consequences of what happens when folks scare parents away from vaccinating and protecting their kids.
Anti-vaccine folks like to talk about death and measles, as long as they can talk about vaccine deaths, something they seem to think happens commonly.
“Over the past ten years in the U.S., there has been one reported death from the measles, and it is unclear based on the medical history of the patient whether and how measles played a role in their death. During the same time period (based on Vaccine Adverse Event Reporting System (VAERS) reports), there have been 105 reported deaths associated with the MMR or MMRV vaccinations.”
Measles Madness: Dr. Brian Hooker’s Statement to WA Legislators
There are two big problems with this statement, that is so often repeated that it is clearly a PRATT – a point refuted a thousand times.
The reports in VAERS about deaths after MMR are not proof of a cause-and-effect relationship.
“Reports of all possible associations between vaccines and adverse events (possible side effects) are filed in VAERS. Therefore, VAERS collects data on any adverse event following vaccination, be it coincidental or truly caused by a vaccine. The report of an adverse event to VAERS is not documentation that a vaccine caused the event.”
Guide to Interpreting VAERS Data
In fact, studies have shown that most of the reports of deaths submitted to VAERS are coincidental and not causally associated with a vaccine.
There are plenty of those that anti-vaccine folks love to ignore.
Where are they?
These deaths are all in the CDC Wonder database.
Before the death of the woman in Washington in 2015, the CDC caused a lot of confusion by stating that “the last verifiable death in the United States from acute measles infection occurred in 2003 when there were 2 reported deaths.”
Does that mean that the measles deaths in 2005, 2009, 2010, and 2012 didn’t happen?
Of course not!
The information in the CDC Wonder database comes from death certificates that are sent in from all over the United States to the National Vital Statistics System. The system isn’t like VAERS though, where just anyone can send in a report. Still, they are unverified, which is why the CDC doesn’t mention them all.
