Cruise Ships Amplify COVID: R0 Jumped to 14.8
Don’t forget, on the Diamond Princess Cruise early in the COVID pandemic the Ro reproductive number for the original lineage went from around 2 to 14.8, cruise ships can be a crucible for respiratory viruses https://t.co/uTxKalftA7

Vaccines Must Evolve for Climate, Megacities, Anti‑Science Era
May 14 I’m at @ucsc Univ California Santa Cruz delivering the annual Sinsheimer Distinguished Lecture in Biology on Global Vaccines in a time of Climate Change, Megacities, and Anti-science https://t.co/R55Ya6D6ys https://t.co/wc3KmeEFeO
Low‑cost Vaccines Delivered, Autism Genes
What a dishonest & ignorant thing to write, I develop low-cost vaccines for global health, 100 million doses administered, without patenting the technology. Also as I’ve detailed we’ve learned a lot about the genetic basis of autism, >100 autism genes,...
Swap Screen Binge for Books, Reclaim Critical Thinking
Someone needs to reduce their screen time, reactivate their public library card, and learn to read a book again. Hopefully gain back some of the critical thinking skills he lost watching Fox News and conspiracy podcasts
Vaccination and Boosters Are Key to Preventing Long COVID
The best way to prevent long Covid is through vaccination and annual updates or boosters https://t.co/m56zh2o2ZY
Pandemic Caused by Zoonosis, Not Conspiratorial Architects
Nonsense. There were no “architects of the last pandemic,” predictions rely on scientific evidence of zoonotic spillover due to climate change/deforestation. But pushing anti-science propaganda or wellness products depends on demonizing real scientists, it relies on their end-user’s gullibility
Debunking Pseudoscience Hurts MAHA's Profit From Overpriced Treatments
So MAHA is not happy that by debunking their pseudoscience, I hurt the sales of their ivermectin, hydroxychloroquine, fenbendazole, which they purchase in bulk, repackage, and sell to you after they jack up the price or pair it with an...

Heat Spike Boosts West Nile Risk—Cover Up, Use DEET

RFK Jr. Deflects Measles
1/n Let’s recount his public statements made in 2025 when he was HHS Scty during our awful measles epidemic in Texas and how he undermined public confidence in public health, as 99 kids/adults hospitalized and 2 kids needlessly died....
CDC Suppresses COVID Vaccine Efficacy Report, Raises Transparency Concerns
There’s no more science at DHHS, just fake MAHA ideologies to benefit the corrupt health wellness industry. A modern version of Lysenko Communism. It’s now up to a patchwork of state govts/NGOs. With no crisis we’ll survive, but if a...

Deadly Epidemics Forged Texas and America's Destiny
For my new book @MITPress “Texas Fever Frontiers: How Deadly Epidemics Shaped the Lone Star State & America’s Destiny,” I’m doing a deep dive into our extraordinary history, from Paleo-Indians, to Cabeza de Vaca, Franciscan Missions, Austin Colony, Republic, Confederate...
MAHA Pushes Revival of Discredited Snake‑oil Cures
In my @BakerInstitute article I explain how MAHA seeks to restore the fake medical cures and snake oils, which the Flexner Report thankfully shut down in 1910, homeopathy, ecclectism, botanicals, so they could sell their nostrums and make money, they...
U.S. Researchers Face Cuts as DHHS Fuels Pseudoscience
1/n For U.S. medical researchers, shrinking labs and bare budgets are the new reality. As I point out: antivaccine is just a foot in the door, DHHS hopes to take down U.S. medical science to prop up wellness influencers &...
Pro‑vaccine CDC
That selecting a physician who understands the importance of vaccines and immunizations is treated as an act of “MAHA betrayal,” likely reflects its payola from corrupt the wellness influencers. If indeed this was the President’s decision, then he did the...
New Rogan‑Spotify Alliance Fuels Anti‑vax Disinformation, Endangering Children
I’m not happy about this new toxic alliance between Children’s Health Defense and Rogan-Spotify. Both are powerful anti-science disinformation organizations, and they don’t care about you or your family. We already had >200,000 needless American deaths from pushing ivermectin and...

Celebrating Science: Discussing #ScienceUnderSiege with Neil Tyson

Vaccines Don’t Cause Autism; Genetics Prove It
Writing garbage in CAPS doesn’t make it true. Not only do we have overwhelming scientific evidence that vaccines don’t cause autism, there’s also the complete lack of plausibility based on what we’ve learned about the >100 autism genes and how...
HHS Ignores Proven Environmental Triggers for Autism
Here’s my statement from @BakerInstitute @RiceUniversity @RiceUNews on why this was always a nonstarter, meanwhile HHS refuses to investigate the few actual know environmental exposures that do interact with autism genes https://t.co/pxLaDLInlf
Exposing Antivaccine Rhetoric Masquerading as Real Science
1/n Here’s a thread on why this is nonsense. I think it’s important to debunk bc increasingly the antivaccine activists and their rhetoric are trying to sound more like real science even though it’s fake.
Patent‑Free COVID Vaccine Reaches 100 Million at $2‑3
Except the opposite, I make low cost vaccines that actually bypass big pharma, our patent-free COVID vaccine reached 100 million people at $2-3 per dose. It’s sad to see so many give up their critical thinking skills for conspiracy sites,...
Low‑cost Vaccines Bypass Big Pharma, Influencers Profit
No, the opposite. I develop low cost vaccines that bypass big pharma. The only shills are those connected to the corrupt wellness influencer industry, which buys whatever it can in bulk cheap so they can jack up the price with...
Anti‑parasitic Drugs Aren’t Cancer Cures, Just Profit Scheme
The congresswoman is wrong. These anti-parasitic drugs do not treat cancer, they’re pedaled by wellness influencers because they are cheap to purchase in bulk, re-package and sell with expensive telehealth visits. It’s for their expensive homes and yachts. Most Americans...
Low‑Cost Vaccine Creator Outshines Rogan’s Diet Critique
I make low cost vaccines for global health, including a Covid vaccine technology for $2-3 per dose reached 100 million people, bypassed big pharma, didn’t make money, and all these Rogan types can talk about is a joke I made...
Great Barrington Declaration: Baseless Propaganda Fueled by Oil Interests

Reassembling ACIP Is Wasteful Under Anti‑vaccine HHS
Look, reconvening ACIP in any form when you have incurious antivaccine activists/ideologues in charge at HHS = waste of U.S. taxpayer dollars. Until there are changes at HHS, there’s no point. For RFK Jr ACIP is meant to legitimize dangerous...
Scientists Advance mRNA Immunotherapies for Cancer, Funding Lags
Now in addition to our @TexasChildrens @BCM_TropMed protein vaccines for global health, our scientists are refining the mRNA technology for new immunotherapies for pancreatic cancer and triple negative breast cancer, if only the grant support would hold… https://t.co/NEgq6DX4qz

HHS Allegedly Fuels Wellness Influencer Pseudoscience Against Vaccines
ANS self evident, Dept HHS had built a pseudoscience parallel universe for the highly corrupt wellness influencer industry. Attacks on vaccines to prop up fake supplements, ivermectin just the beginning, the peptides are next level, but there’s more coming as...

Anti‑vaccine Activism Cost 200‑300k Lives, Says Author
Yes, among people who refused Covid vaccines during the delta and BA.1 omicron waves in 2021-22, that resulted in 200,000-300,000 needless deaths. They were victims of antivaccine activism driven by politics and the corrupt wellness/influencer industry pushing ivermectin, which did...
Low‑Cost Covid Vaccine Tech Delivers 100M Doses, Bypassing Big
So to clarify, Baylor Coll Med licensed our low-cost protein Covid vaccine technology to four entities: BioE (India), BioFarma (Indonesia), Incepta (Bangladesh), ImmunityBio (U.S./S. Africa). The first two produced and delivered 100 million vaccine doses as Corbevax for India and...
Genetic Testing Confirms Autism, Not Vaccine Injury
My daughter with autism and intellectual disabilities was not “vax injured,” a made up term. In fact through Baylor Genetics her autism gene was identified and sequenced and similar to the >100 autism genes published in @CellCellPress https://t.co/93tE96LcmB
Media Vilifies Dissenters to Boost Ratings and Agenda
Actually I was going on Fox News often early in the pandemic but I refused to go along with the fake news about hydroxychloroquine coming out of the White House, and the invitations from the nighttime programming stopped. Midday anchors...
Read Books, Not Conspiracies, to Support Low‑cost Vaccines
Ummm, maybe on the day you decide to visit a library and read a book instead of relying exclusively on fake conspiracy sites to spoon feed you disinformation for their political or financial advantage. So likely never. I develop low...
HHS Undermines U.S. Biotech, Promotes Pseudoscience
Hasn’t HHS already done enough damage to U.S. biomedical science and biotech? Why kill one of the few things that still works in America? ANS: it’s part of a darker dystopian MAHA vision to elevate pseudoscience in its place. My...
Epidemics Shaped Texas History From Cabeza De Vaca
ANS: Not sure I get your point? Much of my scholarship is on the history of science and medicine, and I’ve a passion for the history of Texas. Now I’m writing a new book with @mitpress on how epidemics have...

19th‑Century American Science Shaped Texas' Early History
For my new book on the history epidemics in Texas with @mitpress I’ve been doing a deep dive on the history of science in America in the 19th century, our nation has an extraordinary story of science in the age...
A Fresh Path for Young Physicians and Med Students
Sound and thoughtful advice from @DGlaucomflecken in my recent article on @BakerInstitute website (our policy think thank @RiceUniversity) I’ve proposed an alternative or parallel for young physicians and med students, it’s a bit out there and still half-baked https://t.co/0NN1omZTWk
IAH Airport Chaos Highlights Leadership Failure

Low‑cost, Patent‑free Vaccines Have Helped 100 Million
A “kazarian?” Is that like a Kardashian? What planet are these X trolls from? I develop low-cost often patent-free vaccines for global health and to help humanity. So far 100 million have benefited from access to our vaccine technologies developed...

Low‑cost Patent‑free Vaccines Challenge Big Pharma, Expose Uninformed Freedom Rhetoric
But…I develop low-cost often patent free vaccines that bypass big pharma and provide access to people who can’t afford them. In the past people who espoused freedom were learned and read books. Now they’re just lazy mindless dummies who think...
Low‑cost Vaccines Saved Half‑million Lives, Ignored for Joke
Seriously? I make low-cost vaccines that reached 100 million people, bypassed big pharma, didn’t make a dime, and saved 300,000-500,000 lives, and they focus on a junk food joke I made 6 years ago, this Rogan crowd, a bunch of...
Rebuilding Vaccine Trust After Ideologically Flawed ACIP Recommendations
Good news for America’s children. ACIP was devoid of vaccine expertise and made harmful and ideologically driven recommendations that went against pediatric medical science. Hopefully we can rebuild pubic confidence in vaccines despite their efforts to undermine it, but it...
