The CDC is an emergency response agency, whether that means responding to a cancer cluster, a measles outbreak, lead poisoning or the next pandemic.

I spoke with @cnn.com about how chaos there jeopardizes the country. kffhealthnews.org/news/article...

Vinay Prasad had YouTube censor Jonathan Howard’s channel because he didn’t like how it made him look.

A petty act by a vindictive, unqualified hack. And more evidence that these frEe sPeEcH warriors have always been petty censors out to silence criticism that they just can’t cope with.

My YouTube channel has like 300 followers and 99% of it is just videos of our medical establishment.

Today, I learned they are trying to censor me, instead of doing their job.

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...
Health secretary RFK Jr. shuts door on U.S. investment in mRNA vaccine research
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.

NEW: With deep job cuts at the FDA, inspectors say the ongoing strain could compromise policing an industry spread across more than 90 countries.

“Things will be missed, we are going to have a lot less safe drugs,” a former inspector said.
FDA Layoffs Could Compromise Safety of Medications Made at Foreign Factories, Inspectors Say
Beyond staff cuts, the departures of some longtime investigators in recent months have left less experienced people tasked with rooting out dangerous manufacturing practices.

Things are very bad for U.S. vaccination policy these days and are only going to get worse. In @nejm.org, I examine the recent news about COVID-19 vaccines and ACIP, what likely lies ahead, and what the medical and public health communities should do to lessen the damage www.nejm.org/doi/full/10....
Revised Recommendations for Covid-19 Vaccines — U.S. Vaccination Policy under Threat | NEJM
A series of recent actions by the Trump administration upend the country’s approach to Covid-19 vaccination and may portend a broader shift in the government’s role in protecting the public health.

BREAKING: The FDA has approved a twice-yearly injection that provided a near-perfect shield against H.I.V. infection in clinical trials. But the Trump administration has gutted the programs that might have paid for it in low-income countries

Feeling a lot like I did in early days of the pandemic these days. It is so clear what’s coming: The people that will die because of cuts in global health, because of cuts to research, because of the concerted anti-vaccine push.
It’s clear what’s coming, but we will have to wait to count the dead.🧪

Reminder: Nobel-prize winning PCR (1983), used in basically all genetic tech today, was only possible because of extremophile bacterium discovered in 1964 in Yellowstone funded by a small ~$80k NSF grant with no obvious application at the time. #science 🧪

the 10 out, 1 in policy is agency-wide, not at all specific to cell/gene therapies and there was no mention at that meeting of deregulating or changing any regs (RFK was talking about adding some, and asking for requests/lists on which to cut)
amwhelan.bsky.social
RFK Jr's tenure at HHS is shaping up to be one of inconsistent, nonsensical, and dangerous overregulation (see, e.g., vaccines) and underregulation (see, gene and cell therapies)

“President Trump has given us an executive order that says for every regulation that we put in place, we have to get rid of 10." HHS & FDA apparently moving forward with broad deregulatory agenda for cell & gene-based medical interventions. www.fiercebiotech.com/biotech/fda-...

An increase of 10.9 million uninsured people, plus millions of others who will lose coverage if enhanced ACA premium tax credits expire this year, would reverse much of the gains in insurance coverage from the ACA.

NEW - A new FDA AI tool that could speed up reviews of medical devices is struggling with simple tasks, like uploading documents, according to two people familiar.

A separate tool, called Elsa, which was rolled out to FDA employees Monday is also having issues.

If someone has to read halfway through your story before finding out Kennedy's step on COVID vaccination today is not in alignment with the scientific evidence you are doing it wrong.
