CDC has been a global leader in public health & played a key role in smallpox eradication. Health depts in red states & blue states rely on CDC expertise & support. The CDC EIS program trains the next generation of public health leaders & disease detectives.

They are burning it to the ground.
JAMA Health Forum Oct 9, 2025 by LO Gostin and P Lurie.
Abstract
The Centers for Disease Control and Prevention (CDC) has long served as the cornerstone of the US
public health system, combining technical expertise, evidence-based policy recommendations, and high-quality health information. Yet, it is undergoing profound weakening by the Trump administration, including major funding cuts, the dismissal and resignation of experienced senior staff, and the erosion of its scientific independence. With tightening political control, public trust in
the CDC is diminishing. Undermining the agency’s reputation and capacities will reverberate for generations, making the nation less prepared for future health emergencies, including diseases of
pandemic potential. At this perilous moment, we document the current assault on the CDC that will inevitably have serious repercussion

BREAKING: Friday night massacre underway at CDC. Doznes of "disease detectives," high-level scientists, entire Washington staff and editors of the MMWR (Morbidity and Mortality Weekly Report) have all been RIFed and received the following notice:

The license remains valid even if the product is not sold in the US. For example, the live shingles vaccine (Zostavax) is still licensed but Merck does not sell it in the US. The left the US market after ACIP made a preferential recommendation for the recombinant shingles vaccine (Shingrix).

There are other monovalent measles vaccines but I think only Attenuvax is licensed in the US. The path to licensure is slow and uncertain.

Correction: The measles monovalent vax (Attenuvax) is licensed in the US but not currently manufactured here.

Merck already makes a monovalent measles vaccine, Attenuvax®.

CDCs demand to break up MMR vax into separate monovalent shots is public health malpractice.
These vax are widely used worldwide. The 2 manufacturers (Merck & GSK) could easily decide to abandon the US market rather than take a big financial risk on clinical development & licensure of separate shots
melodyschreiber.com
Andrew Wakefield claimed without evidence in a retracted study that there was a link between autism and the combination MMR vaccine -- but not separate shots.

Wakefield filed a patent for his own separate shots the year before the study was published.

CDC is being run by politicians now.

"there are few experienced leaders left at the CDC; some 80% of..center leaders were laid off or terminated, or have [left]. Houry was the only permanent career official in CDC's office of the director... there were 10 political appointees remaining, she said."

Record warm ocean temperatures continued in September across the North Pacific Ocean, with a number of consequential impacts (including on downstream weather patterns).

This graph shows the average for a band across the midlatitudes for every September from 1854-2025 using @noaa.gov ERSSTv5 data.
Green line graph time series of average sea surface temperature anomalies for each September from 1850 through 2025 for only the midlatitude region of the North Pacific Ocean. There is large interannual variability, but an overall long-term increasing trend. Anomalies are computed relative to a 1981-2010 baseline. 2025 is a record high.

“If you add the conspicuous absence of pro-vaccination messages to the glut of misleading statements from top health officials about vaccine safety and effectiveness, the federal government’s effort this year looks more like a proactive campaign to discourage vaccination.”

ACOG reaffirms that acetaminophen is safe for managing pain and fever during pregnancy. No reputable studies support suggestions like those in HHS’s recent announcement linking acetaminophen use in pregnancy to autism; in fact, high-quality studies show no such risk. https://bit.ly/47Wxc59

Medical ethicist Arthur Kaplan, quoted in the NYT:

“The announcement on autism was the saddest display of a lack of evidence, rumors, recyling old myths, lousy advice, outright lies & dangerous advice I have ever witnessed by anyone in authority in the world claiming to know anything about science”

This MAGA/MAHA/Trump/RFK Jr/Dr Oz/Dr Bhattacharya press conference right now is quite possibly the worst press conference—from the viewpoints of medicine, public health, & medical ethics—that I’ve ever seen. These men are so shameless & deeply irresponsible. Wherever happened to science & evidence?
belongia.bsky.social
This large Swedish study found no association between acetaminophen & autism using matched sibling controls. Also no dose-response effect. Ppl who use acetaminophen while pregnant differ in many ways from those who do not, & using sibling controls was a great way to reduce unmeasured confounding
 Discussion

Sibling control analyses found no evidence that acetaminophen use during pregnancy was associated with children’s risk of autism, ADHD, or intellectual disability. This suggests that the small increase in children’s risk of neurodevelopmental disorders associated with acetaminophen use observed in statistical models without sibling control may have been due to unmeasured confounding. In addition, sibling control analyses did not identify a dose-response association between acetaminophen and neurodevelopmental disorders.

If I could just summarize 1 sentence from the new National Academy of Sciences study on climate, boldface, flashing red, it would be:

"the evidence for current and future harm to human health and welfare created by human-caused GHGs is beyond scientific dispute."
