Two Verifiable Anecdotes are the Mathematical Proof that Vaccines Cause SIDS and Autism
By STEVE KIRSCH
I’m going to share two, verifiable anecdotes, that prove, without a doubt, that vaccines cause SIDS and autism. Basically, the medical community claims black swans don’t exist. I easily found them.
Executive summary
Most of the SIDS cases (likely 75% or more) are due to the childhood vaccines. Vaccines are the main cause of autism as well, likely 75% or more.
In fact, pediatric clinics that avoid vaccines have zero, or near-zero, rates of SIDS and autism.
In this article, I’m going to discuss how just two black swans can destroy the medical consensus by proving that the medical community couldn’t have gotten it right on their claims that vaccines don’t cause autism or SIDS:
- A police officer who investigated 300 SIDS cases over a 7 year period (about 3 to 4 cases per month), observed that 75% of the cases happened within 48 hours after a vaccine.
- A couple who got their triplets (not identical) vaccinated all developed autism within hours after the shot (and each other).
These anecdotes happened, and they are “statistically impossible” to have happened by chance (at least not in our lifetime).
I don’t believe it is possible to attack this data or explain it away.
Too many SIDS cases happened within 48 hours of the vaccine for the vaccine not to have caused the deaths
At the time, I wasn’t sure how to calculate the probability of that happening.
But now, thanks to Professor Norman Fenton, I do.
If SIDS is just randomly happening to babies, and babies are vaccinated every 60 days like clockwork, the chance of a SIDS death happening within any 48 hour window post-vaccine is 1/30.
So if there are 300 babies who died of SIDS, we’d expect that 10 of them, on average, would happen within every 48 hour window post vaccine.
So what are the chances of 75% of these deaths (or more) happening within 48 hours after the shot?
The calculation is trivial to get the chance of seeing 225 deaths or more:
>>> poisson.sf(225-1,10)
3.7718601504237225e-213
That’s not a typo. 10 to the -213. That’s as close to impossible as it gets.
In other words, if SIDS is randomly happening with respect to the time of vaccination, it is impossible to have made this observation. We can cherry pick all we want, we’ll never find a cherry like this to pick. Ever.
This leads to the inevitable conclusion that the vaccines are the primary cause of SIDS, and that they are, at a minimum, causing 75% or more of all SIDS cases.
What’s so special about this police officer
Few other police officers in the world would ever ask such a question because they all know that “it couldn’t be the vaccine.”
So we were lucky enough to find a police officer that asked the question for each of her cases.
And by the way, even if she got it wrong and only 10% of the cases were within 48 hours of the vaccine, there is, by random chance, less than 1 chance in a million of observing that.
Our autism anecdote is also impossible if vaccines aren’t causing autism
Did that happen by chance? It happened within hours of their vaccine injection.

The McDowell triplets are conclusive proof that vaccines can cause autism. All three kids got autism the same day. The chance of that happening if autism is happens randomly to kids is less than 1.66e-13.
Meaning it wasn't "bad luck." It was the vaccine. https://t.co/UGSQuFFO1P

Again, the calculation is trivial.
Say kids only get autism between ages 1 and 4 to be conservative, so an exposure window of 3 years = 1095 days. The current rate of autism is 1 in every 35 kids per the CDC, but the McDowell triplets were vaccinated on June 25, 2007.

So around 1 in 100 kids would get autism in the 1095 day exposure period back in 2007.
So what’s the expected number of cases of autism in a single day per child? Pretty darn low: 1e-5. So if you have 3 kids, you’d expect to get 3e-5 autism cases in any 24 hour period, on average in 2007.
To see 3 (or more) events in a 24 hour window when you expected to see 3e-5 events is:
>>> poisson.sf(2,3e-5)
4.499898751214992e-15
This means that the McDowell triplets couldn’t have possibly happened by “bad luck.”
The vaccine they were given just hours earlier is the only possible way this event could have happened.
This means vaccines can cause autism.
We didn’t need more than one anecdote to prove that conclusively.
Speculation re: genes cause autism to happen at the same time
If you want to make the hand-waving argument that it is just a coincidence because triplets all get autism at the same time, simply show me a case where the autism happened in triplets all on the same day where a vaccine was not involved.
Also, explain this anecdote where one twin was given the vaccine and developed autism, and the twin not given the vaccine didn’t. You can simply show us the opposite anecdote where after the vaccine shot, the twin who did not get the vaccine got autism and the twin who got the vaccine did not get autism.
If you cannot provide evidence for either, your argument lacks evidentiary support and is simply not credible.
These two verifiable “black swan” anecdotes should be all that is needed to disprove the null hypothesis and totally discredit the medical community on these important issues
It takes only a single verifiable sighting of a “black swan” to prove that the consensus was wrong.
That’s what we have here: a black swan for SIDS, and a black swan for autism.
The medical community would be best to embrace this and admit their mistake now because the longer they deny this, the less credible they will be in the eyes of the public.
They surely cannot argue against either of these observations.
But I welcome challenges by anyone who thinks they can!
See my pinned tweet for details for how to challenge me.
Fact checkers wanted! Your opportunity to be a hero!!
Think of the enormous good you would do by validating that the medical community has been misinforming the public on SIDS for decades!
And of course the McDowell story is easily verifiable without contacting me; just watch this short clip from Vaxxed II.
You will accomplish four valuable things by fact checking me:
- Embarrass the medical community
- Create enormous distrust in “medical consensus”
- Cause parents of kids who died from SIDS to seek justice
- Save lives by letting parents know just how dangerous the vaccines are
Summary
Will the medical consensus change? Unlikely, even if these are published as case reports in the medical literature, they’d ignore it as an “anecdote” because that’s what they do. But that’s not science. Both anecdotes are verifiable and would be impossible to happen under the null hypothesis. So any real scientist would have to reject the null hypothesis. The problem is that there are too few real scientists left in the world because they would lose their job, lose their NIH funding, and/or lose their medical license if they speak out against the medical consensus.
So even though the medical consensus won’t change, I thought you all should know the truth: vaccines are the primary cause of SIDS and autism.
