RFK is lying about thimerosal. 🧪 Thimerosal = ethylmercury ≠ toxic 💉 Used safely for decades 🌍 Needed for global flu vaccine access I explain thimerosal & everything else in vaccines. 🎧 Listen or read: www.infectiousdose.com/post/episode... #Vaccines #Science #ThimerosalTruth

New episode out now!!! Think COVID’s over? Think again.

Thank you AAP!!!

This is a travesty & a nightmare. The US was a founder of @gavi.org. It lowers global vaccine costs, has vaccinated 1B children, & averted 19M deaths. This pull out will cost 100s of thousands of children's lives a year - and RFK Jr will be personally responsible. www.politico.com/news/2025/06...

Teen Vogue has some of the best US political analysis anywhere:

I only took one picture at the NSF. The meetings were confidential and we took our work seriously. We approached our responsibility to evaluate taxpayer-funded work with both great care & excitement about the future. It's incredibly sad to watch the casual destruction of so much hard, essential work

Up to 40% of Hepatitis B infections are actually acquired in childhood and kill thousands of Americans per year.

Dropping at midnight: a new Infectious Dose episode — COVID Critical: Complacency and Consequences in an Unfinished Pandemic Explore the cost of policy drift, reinfection risk, long COVID, and the illusion of normalcy. The pandemic isn’t done with us. #COVID19 #LongCOVID #InfectiousDose

If we trust genetic engineering to save a child from leukemia, why reject it when it could save a child from blindness, malnutrition, or death? We cure cancer with genetic engineering but ban it on the farm. Celebrating one but demonizing the other fuels disinformation that costs lives. 1/

oops turns out some of the new ACIP members have conflicts of interest too www.bloomberg.com/news/article...

Very understandable and I go in-depth on why aluminum as an adjuvant or stabilizer and residual formaldehyde from inactivation are perfectly safe in vaccines in my episode: www.infectiousdose.com/post/episode...

OMG THIS👇

This thread of questions for RFKjr is for you, @aoc.bsky.social

Great idea but fair warning: I've been doing it for years and look how it's turned out for me and everyone like me - defunded, marginalized, passed over in favor of people who are easier to get along with, easier to listen to, less intense. Solidarity, I've discovered, is most important of all

22 years ago I pivoted from working on antibiotic resistance to pandemic viruses. Since then, I've argued that if we care about saving US lives in expectation, advance capacity for producing bird flu vaccine offers by far the greatest expected return on investment. ... We were so goddamn close.

Thank you for explicitly stating that this is a direct contradiction of the @nejm.org piece published last week by Makary and Prasad. It also contradicts CDC guidance. It would be nice if the related @nytimes.com article on this decision was corrected rather than retaining wishy washy phrasing...

Studies show pregnant women and their babies get dangerously sick from COVID and the mRNA vaccines are safe in pregnancy. As usual RFK will get people killed from preventable infectious diseases while he and his family remain safely vaccinated. www.infectiousdose.com/post/episode...

Return trip x2 from #SierraLeone in the last month. #mpox is an awful disease…and preventable - vaccines desperately needed as this outbreak expands. Thanks to our amazing team for helping get supples and PPE delivered. Our work continues…

We tested our H5 mRNA-LNP vaccine in calves (!!!), and I’m happy to report that the vaccine was highly immunogenic. Current studies are underway to evaluate the vaccine in lactating dairy cattle. Fantastic collaboration between Penn and the USDA, funded via the NIH. www.biorxiv.org/content/10.1...

To be clear, these kinds of breakthroughs are going to come to a screeching halt with the current NIH funding cuts. This new treatment is only possible because of decades of basic research. What might be possible 20 years from now if we don't destroy basic research? www.nature.com/articles/d41...

Check out this news story that @nature.com wrote describing our recent preprint where we tested our H5 mRNA vaccine in calves. The data look good and we are currently testing the vaccine in lactating cattle...more to come!

Bird Flu news: Pre-print out of the Hensley lab on May 6th shows "that the H5 mRNA-LNP vaccine induced a robust antibody and CD8+ T cellular-mediated immune response and conferred protection against clade 2.3.4.4b H5N1 infection." This is one to watch! www.biorxiv.org/content/10.1...
