Public health is under attack by a deluge of misinformation. We offer a consensus report from the American Psychological Association summarizing what we know & what interventions are effective in countering it. We provide 8 concrete recommendations. Open-access - awspntest.apa.org/fulltext/202...

No FR announcement, inside 15-days, and now meeting date updated to “TBD” on ACIP website.

One of my wonkiest yet. A deep dive on the single data point from Pfizer's COVID-19 maternal vaccine trial that's being used to argue against vaccination. www.factcheck.org/2025/10/vacc...

Trump is back to calling global warming a "hoax." We break down some of his claims in his U.N. speech. www.factcheck.org/2025/09/trum...

For those with questions about Tylenol, in light of the White House press conference, please see our story: www.factcheck.org/2025/09/trum...

So many claims in the autism presser, many of them familiar to us. Check them out here, including Trump's more novel claim about giving the vaccines in MMR separately. That goes back to Andrew Wakefield (yikes!) & it's not even possible to do! www.factcheck.org/2025/09/repe...

Some good background reading before today's White House announcement, by @kateyandell.bsky.social. www.factcheck.org/2025/09/the-...

Dear ACIP, Informed consent is a state issue. The Vaccine Information Statement is a federal document that needs to be give to people before vaccinating. CDC can change it - after a long process, and in consultation with the Advisory Commission of Childhood Vaccines. 1/2

Today, #ACIP will be voting on #CovidVaccination. I will be examining a PhD viva at the time and won't be able to follow live. So, to anticipate some of the claims that may be made on COVID vaccination in #pregnancy... 🧵 www.cidrap.umn.edu/sites/defaul...

#ACIP meeting today is veritable rehash of many vaccine misinfo claims. Focused a lot on dubious claims of DNA contamination in the COVID-19 vaccines. Please see here: www.factcheck.org/2023/10/scic...

If you read 1 thing today, please make it this: my so-talented colleague @ericboodman.bsky.social explains why babies in the US are vaccinated at birth against hep B — and what the human costs of changing that policy would be. www.statnews.com/2025/09/11/n...

Our comment on the DOE CWG report is done. It tips the scales at 439 pages, approx. 3x longer than the DOE report. This is related to Brandolini's law: The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it. Example: refuting one sentence.

This NYT story links to my story detailing the many flaws in a study RFK Jr. cited during Senate testimony to argue that there is reliable evidence that vaccines cause autism (there isn't). nytimes.com/2025/02/12/u... Final vote on RFK Jr. begins in about 20 minutes.

Let me highlight one claim here that hasn't received a lot of media attention, even though it is a blatant falsehood. (1/4) www.factcheck.org/2025/02/fact...

I was interviewed and extensively cited in this factcheck.org article discussing the methodological flaws in the Mawson paper cited by RFK, Jr. in his confirmation hearings yesterday, and mentions other much more rigorous studies finding no vax/autism association. www.factcheck.org/2025/01/rfk-...

Really nice FAQ!

Make no mistake: Despite what he says (not "anti-vaccine," "an evidence-based person"), RFK Jr.'s track record on multiple health issues says otherwise. A non-exhaustive summary of our previous fact checks of Trump's pick to head HHS. bit.ly/4icMrtw

Just joined! Hoping to find some semblance of the old "science Twitter" here.
