It is impossible to reconcile this administration's alleged commitment to "Gold Standard Science" with their harmful actions against important biomedical research

The damage done - Nature Medicine
When clinical trials are suddenly halted by US funding cuts, there are repercussions for investigators and patients, and they do not stop at borders.

Ever since I learned about this study enrolling I have been eagerly awaiting the results. Researchers in Uganda took a centuries-old cultural practice mothers carrying babies on their backs in cloth wraps and turned it into a public health tool. You got to love it!

Thanks for sharing, Mikki. Just wanted to note for anybody curious and/or in a similar position that babies can receive an MMR shot starting at 6 months.

SO the people actively sowing distrust in vaccines (i.e. many of the people in RFK's new ACIP) are also saying that we need to change safe and highly effective vaccine schedules because of this same lack of trust. Make it make sense!

Finally, an answer came back: we must make changes because trust in vaccines has decreased. “The signal that is prompting this is not one of safety, but one of trust,” said member Robert Malone. 3/

ACIP voted 7-3 to NOT recommend MMRV combo vaccine for kids <4yo. Then in a confusing second vote (1 yes, 8 no, 3 abstentions - some citing confusion), they kept VFC coverage for the same vaccine they just said not to use.
This chaos matters for every family. 1/8

Here's the upshot on hepatitis B vaccination at birth:
- it's extremely safe
- the earlier it's given, the better it protects against transmission from mother-to-child
- screening fails to capture many cases and is not done at all in many cases
- perinatal HBV infection is catastrophic

Do NOT allow them to rewrite history with disinformation. #COVID vaccines worked remarkably well and allowed us to come out of a global pandemic. A picture is worth a thousand words.

AAP's immunization recommendations are based only in the science, the needs of children, and the care that pediatricians have for the children in every community. If you have any questions about our recommended schedule, reach out to your pediatrician.

New and important #NatureMedicine correspondence on the health consequences of forced displacement in Gaza

I cannot emphasize enough that the playbook being used against mRNA vaccines (and vaccines in general) is IDENTICAL to the playbook used to restrict voting rights after the 2020 election: actively sow public distrust, then cite the distrust you sowed as an independent reason for your desired policy

As a vaccine for broad public use, mRNA technology has failed to earn the public’s trust.

The mainstream media has already forgotten about this, of course. It's not convenient to explore the fact that the HHS secretary and his MAHA movement are quite literally jeopardizing the safety of healthcare workers by amplifying dangerous (and incorrect!) conspiracy theories.

Rocky start for new #CDC director Susan Monarez, whose first week was punctuated by Friday's attack. Her first all-hands meeting lasted ~13 minutes, with technical challenges with dead air for a time & some staff unable to join the call. "This is a mess," one said. www.statnews.com/2025/08/12/c...
CDC leaders attempt to reassure staff after shooting, but meeting is brief
An all-hands meeting at the CDC to discuss the attack on the agency on Friday was brief and chaotic, staffers say.

Agree, it makes very little sense. I also genuinely wonder about the logistics and ethics of conducting trials to establish potential efficacy of anti-measles antibody therapeutics. This is a very different setting than, say, for testing anti-RSV antibodies.

Important to remember that Russell Vought has directly benefitted from NIH-funded research. His daughter, who has cystic fibrosis, takes Trikafta: www.motherjones.com/politics/202...
Sadly, it seems that he is perfectly OK destroying innovative research that could benefit other families.

🤔I am curious about the ethics and logistics of demonstrating efficacy of an anti-measles antibody & about the strangely optimistic perspective that anti-vaccine/vaccine-hesitant parents would be willing to give their children a drug like this given their general attitudes towards modern medicine.

As the US hits a 33-year high in measles infections, there is now a "race" to find a treatment for the disease.

One pharma company "is banking on a continuing decline in vaccination rates to fuel a need for measles treatments—and in turn, more investor interest"

The Race to Find a Measles Treatment as Infections Surge
The measles vaccine was so effective the disease was considered eliminated in the U.S., but a resurgence of outbreaks is spurring a need for drugs.

(2/2) It's also problematic that this @nytimes.com article has no quotes from Republican Senators who provided the decisive votes for RFK -- Cassidy, Collins, Murkowski. It appears RFK perjured himself at the confirmation hearings -- do they care? Do they care about the toll of his decisions?

(1/2) "At the outset of his tenure, it seemed that Mr. Kennedy might not allow his skepticism of vaccines to influence national policy"

Huh? Lots of people warned that this would happen...

The mRNA vaccine platform has already been assessed across diverse clinical indications, many with remarkable progress:
—cancer neoantigen vaccines [in patients with refractory disease (e.g. pancreatic)]
—more than 15 infectious diseases
—autoimmune diseases
—rare disease for genome editing

Horrible decision but sadly par for the course for the HHS secretary.

Pandemic preparedness in the US has been leveled a crippling blow with the cancellation of multiple #BARDA contracts to help develop mRNA vaccines. No other vaccine platform produces vaccine so quickly; without mRNA, Americans will have a long wait for pandemic vax. www.statnews.com/2025/08/05/m...

Vaccine experts and people steeped in pandemic preparedness expressed horror at the news that RFK Jr. has shut the door in U.S. investment in mRNA vaccine research.
