Ending routine vaccination for hepatitis B at birth, as health secretary RFK Jr. has proposed, would increase the number of chronic infections by as much as 83 percent. www.nytimes.com/2026/10/19/h...

Despite RFK Jr's appointment in the Trump administration and an all Republican congress, regulations that keep Americans healthy are nowhere to be found. In fact, the EPA has quietly revised its website, which for years claimed that PFOA and PFOS had been “phased out” in the US.

So fucking deranged

Indeed they did. This is an important change that will make biomedical science like cancer and dementia research worse, by allowing newly political roles (program officials now under Schedule F/P/C and IC directors chosen by politicals) free rein to choose projects to fund.

Should read the whole thread. When Stand Up for Science, usually a relentless advocate for science, shows why a study should NOT be done, it’s time to listen.

Additional details on what @standupforscience.net found when it sent an on-the-ground investigator to Guinea-Bissau to examine the ethics approval process for the controversial hep B vaccine trial: 🧵👇

It's unconscionable to give some children a vaccine we know works and deny it to others.

The NIH proposal to conceal reviewer scores from program officers, investigators, and advisory councils is ill-conceived, introduces disproportionate weight to small percentile differences, diminishes the role of scientific peer review, and should be withdrawn in its entirety. a 🧵

To this day, the @standupforscience.net work I'm most proud of is fighting this study. Please help us stick a fork in it by signing our petition to Congress: www.standupforscience.net/petition-to-...

In Feb 2026, we dispatched an experienced associate with decades of West Africa investigative journalism expertise to conduct an on-the-ground fact-finding investigation. We presented this to Congress in a closed briefing. A thread of our findings🧵 www.standupforscience.foundation/policy-and-a...

Can't get to an in-person rally Saturday? @standupforscience.net has you covered with this official virtual rally! Big name speakers are joining us, don't miss it!! 👇👇👇

Michael Lewis, @authormichaellewis.bsky.social , best-selling author of Moneyball, The Big Short &, most recently of Blockers, the story of the DOGE destroyers & the federal employees & others who resisted is scheduled to speak at our Virtual & Accessible Get Out the Vote Rally on Oct 17th, 7pm ET!

It's time to take immediate action to halt RFK Jr.’s malicious and harmful study, which will intentionally withhold life-saving Hepatitis B vaccine from thousands of newborns in Guinea-Bissau.

I was surprised how different this was from the movie, especially the ending. Both 10/10 in their own right for me.

This is some spineless garbage from @apapsychiatric.bsky.social. The APA isn’t achieving neutrality with their censorship, they are aligning themselves with the Trump admin. I’ve put them on the running list of compromised institutions.

Whether you are someone with accessibility challenges, stuck at work, a caregiver with parents, kids or patients, or live in a No Kings rally desert - you are welcome at the SUFS No Kings GOTV Rally on October 17th @ noon: tr.ee/zdelKk

The CDC just re-opened a previously shelved study that would withhold the hepatitis B vaccine from children in Guinea-Bissau, despite decades of evidence showing it is safe and effective. This is a violation of human rights, using “science” to harm some of the most vulnerable people in the world.

This is a deep and powerful report from the @standupforscience.net Foundation. It is thorough and deep but worth the time to read. www.standupforscience.foundation/forging-the-...

This is a big deal and an amazing piece of writing from my brilliant colleagues at @standupforscience.net. Go read it. Then join us in the fight.

Today we launched our Assessment section; How We Got Here: Right Wing Strategies and Tactics where we take a deep dive into the players, objectives, and tactics used to rob the scientific ecosystem of its value to the public.

Forging the Future of Science and Democracy is a guide for rebuilding a resilient scientific ecosystem that works for the public good. 4 steps we must take to ensure we don’t rebuild a system with the same injustices & vulnerabilities: Assessment, Accountability, Deconstruction, & Reconstruction.

The anti-science, anti-democracy Trump Administration has placed the American scientific ecosystem in a precarious position. We needed reform before Trump 2.0…but now we need a full reconstruction. This is a once in a lifetime opportunity to dream big about a brighter future for science & democracy.

People have asked why we aren't involved with Neil deGrasse Tyson...this is why. @standupforscience.net does not endorse candidates with accusations of sexual misconduct and we do not collaborate with people who have accusations of sexual misconduct. PERIOD. Welcome to the matriarchy.
