This isn’t about a single controversial claim.

According to NewsGuard, 118 provably false narratives have been promoted by Robert F. Kennedy Jr. and Children’s Health Defense since 2016.

This is a pattern. 🧵 2/ The Pattern

This isn’t about a single controversial claim.

It’s a systematic pattern across domains:
• Vaccines
• COVID-19
• HIV/AIDS
• Public health policy
• Food & environment

When false claims span everything, it’s not just skepticism—it reflects a broader pattern.

1/ In debates about vaccine history, people often point out that deaths from infectious diseases were falling long before vaccines arrived.

This is a FACT. But it’s not a "gotcha" against vaccines—it’s a triumph of engineering and infrastructure. Let’s dive in. ⬇️ 2/ If we look at the first half of the 20th century, mortality (death) plummeted.

Why? Because we stopped living in "filth" conditions.

The biggest hero wasn't a pill or a needle; it was the civil engineer. 🛠️🏙️

1/ RFK Jr. often tells Congress that medical measures (vaccines/antibiotics) only caused 3.5% of the mortality decline since 1900, citing McKinlay (1977).

It sounds like a "gotcha," but it relies on a massive misunderstanding of public health. 2/ McKinlay’s study measured MORTALITY (death). By 1960, deaths from diseases like measles had dropped because of better supportive care and nutrition.

But death isn't the only metric for a "successful" society. What about the suffering in between?

1/ RFK Jr. claimed before Congress that the Guyer study (2000) proves vaccines had “almost no” role in reducing mortality. He called it a “CDC study.” This is misinformation. The truth is much more complex—and supportive of vaccines. ⬇️ 2/ First, Guyer et al. (2000) wasn't a "CDC study." It was published in Pediatrics by academic researchers, though it used national statistics. The researchers' actual conclusions were the opposite of what Kennedy claimed.

1/ In recent testimony, RFK Jr. cited studies by Guyer (2000) and McKinlay (1977) to claim vaccines didn't save us. The claims sound academic, but the interpretation is a masterclass in cherry-picking. Let’s look at the actual data. ⬇️ 2/ RFK Jr. claims a "CDC study" shows vaccines had no role in reducing mortality, referring to Guyer et al. (2000). While sanitation/nutrition helped early on, Kennedy ignores what the authors actually concluded about the modern era.

A promised cause.
A year of shifting claims.

In 2025, RFK Jr. said we’d soon know what causes autism.
That answer never arrived.

Here’s what the evidence actually shows. 🧵 1/ In 2025, a definitive “cause” of autism was promised on a political timeline.

Biology doesn’t resolve that way.

Complex neurodevelopmental conditions do not yield single-cause answers on demand.

THE PLAYERS

“Disinformation has a supply chain.” 1/ Disinformation doesn’t spread itself.

It has a supply chain.

THE PROBLEM

“This isn’t random. It’s a system.” 1/ We talk about misinformation like it’s random.

It’s not.

It’s structured.

And it works because incentives are aligned.

1/ They just turned Ozempic into a pill.

No injections. No friction. Just take it daily and lose weight.

Sounds like a breakthrough.

But there’s a biological tradeoff almost nobody is explaining—and it matters. 2/ GLP-1 drugs don’t directly “burn fat.”

They suppress appetite.

Eat less → weight drops.

But your body doesn’t care about aesthetics. It cares about survival.

And survival changes what tissue gets sacrificed.

1/ During measles outbreaks, vitamin A gets mentioned for a reason.

But recommending cod liver oil for prevention crosses a critical line—from evidence-based care to biochemical risk.

Here’s what actually happens in the liver. 👇 2/ Vitamin A is not just a nutrient.

It’s a fat-soluble signaling molecule stored in the liver.

Unlike water-soluble vitamins, excess isn’t easily excreted—it accumulates.

That’s where the problem begins.

1/ c19early looks like a massive meta-analysis. It’s not.

It’s an advocacy platform that aggregates studies using nonstandard methods that make weak evidence look strong.

Let’s walk through the core methodological problems 👇 2/ Problem #1: Outcome mixing
They pool “the most serious outcome” from each study.

That means:
• Death in one study
• Hospitalization in another
• Viral clearance in another

→ Combined into ONE effect size

That’s not clinically coherent.

Three autism “studies” are circulating online today.

Each reports a striking correlation.

But good science depends on something most viral posts ignore:

the methods.

Before reacting to the conclusions, take a moment to read the abstracts carefully. 2/ Study #1

Researchers surveyed 15,000 families and found that 97% of autistic children had at least one vaccinated parent.

At first glance, the number looks compelling.

But pause for a moment.

What percentage of adults in the general population are vaccinated?

1/ John Beaudoin’s book The Real CDC claims COVID deaths were inflated through manipulated death certificates in Massachusetts.

But what do the data — and public health audits — actually show?

Let’s take a look. 🧵 2/ Massachusetts revised how it counted COVID deaths in 2022.

Why?

To increase accuracy — not inflate numbers.

The state shifted from a 60-day to a 30-day positive test window to better reflect deaths actually caused by COVID.

Transparency ≠ conspiracy.

THE NANOPARTICLE REVOLUTION: Re-educating the Blood-Brain Barrier.

New research from a Spanish and Chinese consortium has unveiled a "supramolecular drug" capable of repairing the BBB's natural waste-disposal system to treat Alzheimer’s.

A thread on the future of AD therapy. 1/ The Problem: In Alzheimer’s, the Blood-Brain Barrier (BBB) stops working as a filter and starts acting as a wall.

Toxic proteins like Aβ build up because the brain's natural "trash shoot" is broken.

The Solution: Activating the endogenous efflux pump.

Big Pharma vs Big Wellness….. 1/ Everyone loves criticizing “Big Pharma.”

But almost no one applies the same skepticism to “Big Wellness.”

If profit motives invalidate one industry’s claims…

Why don’t they invalidate the other’s?

About that 10-20X figure:

1/7 In early Dec 2021 → Apr 2022, vaccines + boosters were widely available in the US. The key question isn’t “who died” in raw counts—it’s age-adjusted death RATES by vaccination status. 2/7 Age-adjusted death rate ratio (RR) = (death rate in unvax) ÷ (death rate in vax/boosted), standardized for age. That’s how you compare “like with like” when risk rises steeply with age.

1/ If you’ve ever seen someone post a VAERS screenshot and say: “Look how many people died after this vaccine!” This thread is for you. Let’s walk through what VAERS is — and what it is not.

1/ Cardiometabolic health = integrated function of vascular + metabolic systems that drives ASCVD, HF, CKD, MASLD, and T2D risk. Domains: adiposity distribution, BP load, atherogenic particles, glycemia/IR, ectopic fat, end-organ injury.

1/ 🧵 A CHD manuscript (Feb 2026) argues aluminum vaccine adjuvants cause ASD and claims it “meets all 9 Bradford Hill criteria.” It’s a narrative synthesis, not a randomized trial or new cohort study. (PDF p1–2) 2/ Their headline statistic: ASD prevalence rose “80-fold” and “correlates” with vaccine schedule expansion (r=0.91). That’s a time-trend correlation—useful for hypotheses, weak for causation. (PDF p1)

GLP-1 is often framed as a drug target—but it’s first a physiologic gut hormone, released in short pulses when nutrients reach distal L-cells. This thread explains how modern diets silence that system—and how endogenous GLP-1 signaling can be restored. 🧵👇 1/ GLP-1 isn’t just a drug target. It’s a native gut hormone designed to be released in short pulses when nutrients reach distal intestinal L-cells. Modern ultra-processed diets short-circuit this system.

📚 Incretin effect (Nauck et al.)

1/ GLP-1 receptor agonists work—but they bypass normal physiology. This thread reviews how endogenous GLP-1 signaling is suppressed by modern diets, and how gut-centric interventions can restore physiologic, pulsatile incretin release. 🧵👇 2/ The incretin effect shows that oral glucose triggers far greater insulin and satiety responses than IV glucose. This gut-dependent amplification is mediated primarily by GLP-1 and GIP—not by glucose alone.
