FDA is refusing to consider Moderna's mRNA flu vaccine. Yet, as @angierasmussen.bsky.social explains, if we had mRNA vax technology for flu, we might have been able to quickly update this season's shots to cover subclade K before it hit the US. @jackiefmogensen.bsky.social reports @sciam.bsky.social

You've heard of semaglutide (Ozempic/Wegovy), tirzepetide (Mounjaro/Zepbound). But there are new drugs coming, ones that leave these in the dust, and leave clinicians and scientists asking: Can people lose too much too fast? www.scientificamerican.com/article/new-... By me.

Important story from @laurenjyoung.bsky.social, who was one of my amazing freelance editors at @sciam.bsky.social. Health Experts Slam Possible FDA ‘Black Box’ Warning for COVID Vaccines www.scientificamerican.com/article/heal...

"The science is clear: the benefits continue to outweigh the risks by a wide margin,” @kkjetelina.bsky.social says of the black box warning FDA is reportedly considering adding to the COVID vaccines. By @laurenjyoung.bsky.social @sciam.bsky.social www.scientificamerican.com/article/heal...

A thing that serves me well: ALWAYS take very seriously anything @kkjetelina.bsky.social says; she's 1 of the most trusted epidemiologists If FDA thinks risks>benefits, she says, "transparency about their data & reasoning is essential. Closed-door analyses won’t cut it. Americans deserves better.”

Some good news: U.S. sunscreens might finally be able to use a key UV filter ingredient found in many popular brands made in Japan, South Korea and European countries. The last time the FDA approved a new sunscreen ingredient was 1999. @sciam.bsky.social www.scientificamerican.com/article/u-s-...

Reporting on vaccine side effects is challenging, but important.

1. #Flu activity is picking up in the US. A 🧵 5 jurisdictions reported high levels of flu activity to #CDC in the week ending 11/29, the week including Thanksgiving. It's conceivable that numbers could jump in the next few weeks, both because of holiday travel & reporting delays due to the holidays

“In my career, I have seen children with hepatitis B. I’ve seen children die of liver failure, which is a horrible death. I would never wish this on anybody,” say Yvonne Maldonado, Stanford pediatrician. These risks have now increased under the new ACIP vaccine vote today. More @sciam.bsky.social:

An CDC advisory panel voted today to end universal Hepatitis B vaccination at birth. If adopted by CDC, this would reverse a longstanding policy that has been widely effective at lowering hep B cases and deaths in children, @laurenjyoung.bsky.social reports www.scientificamerican.com/article/cdc-...

The 2025 Nobel Prize in Medicine goes to some neat fundamental research on the immune system: peripheral immune tolerance. It's what keeps the body's defense mechanism in check—and could be key to new therapies for autoimmune disorders. @sciam.bsky.social www.scientificamerican.com/article/2025...
