Weird some scicomm accounts gave the new “Tylenol in pregnancy & autism” review some weight. They don’t know the lead author, Baccarelli, had the exact claims thrown out of federal court for having ZERO scientific merit, when he was a paid “expert witness” in lawsuits against Tylenol makers. 1/

Toxicology principle that needs to be mainstream: The dose makes the poison. That’s true of everything. Water. Oxygen. Vitamin A. Vitamin D. Aspartame. Formaldehyde. A single pear contains 120 times MORE formaldehyde than what might be in a vaccine. 1/

I spoke at a clinical toxicology conference today about how chemophobia & disinformation harms science, medicine, & health. It rounds out a busy couple weeks of conference talks. While we’ve been watching targeted attacks on vaccines, there are MANY other biomedical fields under attack too. 1/

It’s cool that RFK Jr and his cherry-picked team of science deniers are going to try to prevent Americans from accessing a medicine that can prevent nearly all cases of chronic hepatitis and 50% of liver cancers this week. So healthy, right?

RFK Jr is using CDC’s Advisory Committee on Immunization Practices to undermine life-saving vaccines. Instead of credible vaccine & regulatory experts, he filled it with science deniers and conspiracy theorists like Robert Malone, Martin Kulldorff, & Retsef Levi. Watch ⬇️ youtu.be/_2N86lnN3vA?...

Appointing anti-science conspiracy theorists to our national advisory panel for vaccine recommendations won’t make ANYONE in the US healthier. It WILL make us less healthy, especially kids. Reducing access to vaccines will cause more acute AND chronic illness. For all of us.

Example: Charlatans “prescribe” vitamins & minerals for cancer. What happens? People die more frequently and faster than those who take meds. Pseudoscience and medical conspiracism is deadly. More detail in this article I wrote: 🔗 news.immunologic.org/p/cancer-mis... 🔗

Gun violence is the leading cause of childhood death in the US today.

“I think it's worth to have a cost of, unfortunately, some gun deaths every single year so that we can have the Second Amendment to protect our other God-given rights” —Charlie Kirk Gun violence is not an inevitability in the US. Data-driven regulation can save lives. Will people see the benefit?

Vaccines don’t cause autism. Tylenol (acetaminophen) doesn’t cause autism. Miniscule trace pesticide residues don’t cause autism. Aluminum doesn’t cause autism. Fluoride doesn’t cause autism. The biggest predictor of autism? Genetics. And we recognize autism better today. 1/

RFK Jr’s HHS endorsed personal belief vaccine exemptions. We’ve been here before: 2015, California. School vaccine “requirements” let parents opt out for any personal belief. In some counties, kindergarten MMR rates dropped to 50%. A measles outbreak starts at Disneyland. 1/

RFK Jr’s HHS endorsed religious exemptions for vaccines. We KNOW what will happen. 1991, Philadelphia. 2 fundamentalist churches that reject vaccines & medical care have schools filled with unvaccinated kids. Measles rips through the school & neighborhoods. 1/

Reminder: RFK Jr has made MILLIONS demonizing a vaccine that blocks viral infections AND prevents CANCERS Cervical cancer Penile cancer Oropharyngeal cancer (throat) Vaginal cancer Anal cancer Vulvar cancer I guess he DOESN’T care about reducing chronic illness after all… 1/

Any Senators here? I’m a biomedical scientist with immunology, cancer, infectious disease expertise. RFK Jr lied to you in his confirmation hearings. Repeatedly. Provably. He’s lied to EVERYONE for 30+ years. Repeatedly. Provably. He WILL lie today. Repeatedly. Provably. 1/

Florida’s decision to erase school vaccine requirements will cause preventable illness and death. Not just for kids in Florida. For whole communities. Of all ages. Across the country. Because pathogens don’t follow state lines. 1/

What’s wild to me: NOW, media outlets & medical organizations are “stunned” by the damage RFK Jr. is doing to CDC, other health agencies, & public health. Me & my colleagues have been screaming about him for years. Years. Even more so in the last year. We were called hyperbolic. 1/

RFK Jr cut half a billion dollars in research funding for mRNA vaccines. He & Marty Makary claim mRNA vaccines are “risky” so they’ll shift to “traditional, older” vaccine tech that’s “safer.” Guess what? We used to immunize people by blowing powdered smallpox scabs up their noses. 1/

Just to follow on: The Environmental Working Group (EWG) ALSO wrote a “report” decades ago blaming mercury in vaccines for autism. They tried to wipe that from their history, conveniently. EWG is probably the 2nd worst anti-science org behind RFK Jr’s Children Health Defense.

For those unaware: RFK Jr has been spreading anti-vaccine lies for over 20 years. This is not new. This is not “since COVID.” He wrote a 2005 article in Rolling Stone blaming vaccine ingredients for autism. Be aware of this history. He is a millionaire because of the disinformation HE created.

Hi, immunologist here: (a scientist who studies immune & inflammatory processes) RFK Jr is talking absolute bullshit when he says he can “see in kids faces that they have inflammation” That’s NOT how immunology works. He is an anti-science profiteer. Start calling him such.

Andrew Huberman is a wellness influencer: his appearance on Bill Maher is amplification of that. Don’t forget Bill Maher platforms anti-science rhetoric, including germ theory denialism. I've written a LOT about Huberman and his pseudoscience tactics. news.immunologic.org/p/is-andrew-... 1/

Sterilizing immunity: the latest anti-vaccine rallying cry. A real thing co-opted by anti-vaccine activists to undermine vaccines. By anti-vax logic, if a vaccine doesn’t doesn’t block all infections, it’s a “failure.” MOST vaccines don’t elicit sterilizing immunity. No one pretends they do. 1/

Why is Red Dye 40 not banned? Because science is based on evidence, not vibes. Not only is it not banned, it’s deemed safe by experts globally. Red 40 has the SAME acceptable daily intake in US, Europe, Canada, Australia, Japan: 7 mg per kg body weight per day. Watch⬇️ youtu.be/yHPm_hxNorw?... 1/

People weren’t healthier “back in the day.” In 1960s, life expectancy was in the 60s vs. 79 today. Testicular cancer? 95% fatal. Today? 95% survivable. Same with MANY cancers. Infections. Vaccine-preventable illness. We live longer & healthier lives today bc of science. youtu.be/rDx7LrBiMH0?...

mRNA STILL doesn’t change your DNA. That’s true whether it’s mRNA made by every cell in your body ALL THE TIME or mRNA molecules in medicine. Anti-science activists weaponize their lack of basic science knowledge to spread fear & harm society. Watch⬇️ youtu.be/UzdMMq60mmU?...

It’s my birthday. I’ll be at the vet oncologist with Maxwell, diagnosed with large cell lymphoma last week. Hoping 38 is kinder than last year. For my birthday, sign up for my free newsletter. I want you to have & use accurate science information with friends & family. 🔗 news.immunologic.org

Now that RFK Jr has tried to bully a scientific journal into retracting a huge study showing —AGAIN — that vaccines aren’t linked to autism… Is the media ready to stop calling him a “vaccine skeptic” and say what he really is? An anti-science conspiracist who profits by LYING to people. 👀

My latest: Pseudoscience Support @wired.com I cover it ALL. RFK Jr & MAHA misinformation, Calley Means’ cancer lies, glucose monitors, hormones in milk, food dyes, Dirty Dozen, fluoride, mRNA vaccine, chemicals, diabetes, hep B, beef tallow, seed oils, and more. Watch ⬇️⬇️ youtu.be/hfBJTpewWos?si

A study concludes: more colorectal cancer diagnoses in adults 45-49 is a result of…screening age being lowered to 45 in 2021. 😐 ⬅️ my surprised face. I wrote about this exact thing when media outlets were fear-mongering about “skyrocketing cancer rates” among adults <50. 1/

Lyme pseudoscience is not new. It’s been around for decades & is a model for “newer” pseudoscience trends. Lyme disease is a popular scapegoat among the affluent elite. It undermines real science & public health work being done on this infection. 1/

🧂Table salt doesn’t explode when you add it to soup. 💉Saline solution doesn’t explode when injected into your veins. 🥤Your organs don’t explode when you drink Nuun, Tailwind, Gatorade, or other electrolyte drinks. Everyone agrees on these, right? These aren’t issues that are debated. 1/

Vinay Prasad resigned as head of FDA’s CBER. CBER oversees all biologics: cell & gene therapies, monoclonal antibodies, blood products, vaccines. It’s good since he is 100% unqualified & spreads anti-science rhetoric, but conspiracist Marty Makary likely has another ally ready to install.

The reference dose of METHYLmercury is: 0.1 μg/kg/day. 🐟 A 6 oz can of albacore tuna contains 30-50 μg of METHYLmercury. That’s 4.4-7.3 TIMES more methylmercury than the daily threshold if you weigh 150 lbs (68 kg). Do you panic about eating a can of tuna? I bet no. 1/

RFK Jr & his HHS has declared thimerosal dangerous. It’s not. The result? US will no longer recommend vaccines with thimerosal (a safe preservative). This lie, now policy, will ripple around the world, destroying vaccine trust, access, & uptake. A thread ⬇️ 1/

Happy Tuesday! And they say chivalry is dead.

Sucrose (cane sugar): glucose & fructose molecule bonded. Your body sees 50% glucose, 50% fructose. High fructose corn syrup is ALSO roughly 50/50 glucose/fructose. Corn syrup: 100% glucose. Enzyme glucose isomerase converts ~50% to fructose. Swapping HFCS for cane sugar in soda ain’t doing shit.

In news, scientists are forced to waste valuable time & resources to conduct ANOTHER largescale study that shows vaccines are safe, effective, save lives, and Don’t cause autism or other health issues. Why? Because anti-vaxxers lie, undermine science, harm children, & erode public health.

I think the issue is people and media have historically sought the wrong people as experts who aren’t equipped to speak about the science behind concerns, so they aren’t addressed adequately. Ex: pediatricians are NOT vaccine scientists so they don’t have detailed knowledge of formulation science.

Why do we have universal newborn hepatitis B vaccine recommendations? Because it saves lives. Hepatitis B Virus (HBV) is NOT just sexually transmitted. It spreads through close contact with a variety of bodily fluids. 1/

Vaccines save 2-3 million lives every year. They are incredibly safe. The risk of a serious adverse event after vaccination is ~1 in 1,000,000. Context: The risk of dying in a car crash: 1 in 100. The risk of peanut allergy: 1 in 200,000. The risk of dying from choking on food is 1 in 2500. 1/

Expansion of Ixodes range (& Lyme as a result) is unlikely related to climate change —though it’s a common assumption. The range has expanded predominantly southward, opposite of climate-change based pattern. It is more about urbanization & human interaction with natural hosts of the tick species.

Lyme disease was not created as a bioweapon. This lie circulates every year. The bacteria have existed for AT LEAST 60,000 years. I spoke with Politico last year after Tucker Carlson lied about it. Joe Rogan is repeating the same bullshit. ⬇️⬇️ www.politifact.com/factchecks/2...

Is there a “diabetes epidemic” among children in the US? No. 0.35% percent of people under the age of 20 have diabetes. 86.6% of those are type 1 diabetics, which is autoimmune. 0.046% of people under the age of 20 have type 2 diabetes in the US. RFK Jr & MAHA love to lie about basic facts.

Why do newborns get hepatitis B vaccine? Because 90% of hepatitis B infections in kids become chronic hepatitis. Because chronic hepatitis causes 60% of liver cancers. Hepatitis B is NOT just sexually transmitted, it’s via ANY bodily fluids. Infants get infected at birth or via family members. 1/

Independence Day is supposed to honor American ideals set forth by our founding fathers: freedom, equality, democracy, opportunity, & collective progress. USA wouldn’t exist without science & public health. We won the Revolutionary War because George Washington mandated smallpox immunization. 1/

If my stepdad Bill hadn’t died in April, the cuts to Medicaid, SNAP, & health services passed by Congress would be fatal. 17 million will lose health insurance. Millions will lose access to food. Hospitals will close. Bill worked his whole life but relied on these. This bill will kill people.

If an “alternative” cancer treatment worked—you can be damn sure scientists would be developing it for physicians to use. No one is hiding natural cures for cancer. Can we STOP listening to people like Mel Gibson, Joe Rogan, Marty Makary, and RFK Jr? Watch ⬇️⬇️ youtu.be/RhUJytYCTyY?... 1/

Acute Lymphoblastic Leukemia (ALL) had a survival rate of 10% in the 1960s. 75% of ALL cases are in kids under 6, btw. Today? It has a survival rate over 90%. That's thanks to: Chemotherapies Scientific research Biopharmaceutical therapies Evidence-based medicine 1/

There’s a statewide recall of raw milk here in PA because it’s contaminated with Campylobacter jejuni. Campylobacteriosis cases are linked to Meadow View Jerseys Dairy milk. If only there was a way to avoid illness like that… 1/

This is thimerosal. It is NOT mercury. You can see that clearly by the chemical structure. It has an ion that contains mercury as a component. That’s it. That’s like saying water is “hydrogen” or air is “nitrogen” — it’s wrong. It’s ALSO been extensively studied for safety. 1/
