🧵 BREAKING: The biggest medical scandal you've never heard of?
For decades, we've given Tylenol to babies like candy. Now mounting evidence suggests it may be linked to the autism epidemic, greatly amplifying the profound damage vaccines have done to children's brain development.
New data shows autism rates hit 1 in 31 children in 2025.
Here's what they don't want you to know👇
For decades, we've given Tylenol to babies like candy. Now mounting evidence suggests it may be linked to the autism epidemic, greatly amplifying the profound damage vaccines have done to children's brain development.
New data shows autism rates hit 1 in 31 children in 2025.
Here's what they don't want you to know👇
1⃣Meet Dr. William Parker - the immunologist who spent 28 years at Duke University before being mysteriously ousted after his Tylenol research got "too controversial"
His crime? Publishing peer-reviewed studies showing acetaminophen might trigger autism in susceptible children
❌Even now, Pharma-biased outlets like the Atlantic publishes smear pieces against him with impunity, ignoring the mountain of evidence he provided them when interviewed. Learn more here: sayerji.substack.com/p/the-tylenol-…

2⃣The evidence is staggering:
💠15+ animal studies ALL show brain damage in infant mice given Tylenol
💠Male mice affected 4x more (mirrors autism's gender gap)
💠Kids given Tylenol after MMR vaccine: 8x higher autism risk vs ibuprofen
💠Zero increased risk with ibuprofen (which itself is a relatively toxic drug).

3⃣The smoking gun: A 2020 NIH study measured acetaminophen in umbilical cord blood
Results? Babies with highest levels had 3.6x autism risk
This isn't surveys or correlation - it's biological proof measured at birth

4⃣Here's where it gets dark:
When Duke shut down Parker's lab in 2021, the university's Chancellor and President were BOTH on Johnson & Johnson's board (Tylenol's parent company)
Duke rejected an anonymous donor offering to fully fund Parker's research. Why?

5⃣The timeline is chilling:
💠1980s: Aspirin abandoned for kids (Reye's syndrome fears)
💠Tylenol becomes THE children's painkiller
💠Autism rates explode from 1 in 1,000 to 1 in 31 today
💠Countries with limited Tylenol access? Autism remains extremely rare
🚨NOTE: Vaccines and their brain-damaging effects are the primary driver of autism, but together with Tylenol (up to half of pregnant women take it), the mystery of the exploding rates are solved.

6⃣A 2024 Swedish study claimed to "debunk" the link, but Parker's team found a fatal flaw:
They adjusted away the very factors that make kids vulnerable to Tylenol
It's like saying matches don't cause fires after removing wood and oxygen from your analysis.

7⃣The biochemistry: Infants can't properly metabolize acetaminophen. Instead of breaking it down safely, their bodies create NAPQI - a toxic metabolite that attacks the developing brain
We've been accidentally poisoning babies' brains while monitoring their livers

8⃣🚨91 scientists published a consensus statement in Nature warning about acetaminophen in pregnancy
The medical establishment's response? "Keep calm and carry on - Tylenol is safe until DEFINITIVE proof exists"
How many kids affected while we wait for "definitive"?

9⃣RFK Jr's HHS is reportedly preparing to acknowledge the link
Kenvue (Tylenol's owner) stock crashed 9% on the news. Their CEO personally lobbied RFK Jr to suppress the findings📉
The same "safe and effective" playbook we've seen before

🔟This isn't about banning Tylenol overnight. It's about:
💠Informed consent
💠Using alternatives first (natural, evidence-based and safe pain relievers are abundant)
💠Reserving acetaminophen as last resort
💠Researching antidotes like N-acetylcysteine
Parents deserve the truth

1⃣1⃣The most heartbreaking part?
Every parent who gave their child Tylenol was following medical advice. Every pediatrician was following guidelines.
The failure is systemic - from regulators who never required brain safety testing to institutions that silenced warnings

1⃣2⃣We're potentially looking at the most preventable tragedy in modern medicine
💊If even partially true, we could dramatically reduce autism rates by simply changing an over-the-counter recommendation
After billions spent on research, the answer might be: use less Tylenol

1⃣3⃣Bottom line: The evidence can't be ignored anymore
30+ independent lines of evidence point the same direction. Animal studies unanimous. Human epidemiology consistent. Biochemical mechanisms identified.
How much proof do we need before precaution?
Time for answers.
