1/ Pretty amazing new results showing an unexpected benefit of mRNA vaccines. Patients who received a COVID-19 mRNA vaccine within 100 days of starting immune checkpoint inhibitor (ICI) therapy survived almost twice as long. jenndowd.substack.com/p/can-mrna-v... #episky #medsky #cancer

Thinking only of Rosalind Franklin today, and what was stolen from her (and so many other female scientists alongside her).

The early flu season in England continues to build, while the latest Covid wave continues to recede. Latest UKHSA hospital admission data up to 27 Oct.

This is exactly the right response to these headlines

Super interesting (and hopeful) trend, though I really wish the confidence intervals around these estimates were available somewhere @gallup.com? news.gallup.com/poll/696599/...

Are the cardiovascular benefits of GLP-1s just a result of losing weight? Probably not--a significant portion of risk reduction seems to be independent of weight loss. jenndowd.substack.com/p/ozempic-fo... #publichealth #episky #medsky

When I say the study of human populations needs epistemic diversity this short piece show why - thinkers from beyond the silos of demography and public health and economics are doing the WORK and we're becoming fast irrelevant. The meanings of demographic measures are why they matter.

Demography is science, but it's not rocket science. Journalists and related professionals could understand crude birth rate, general fertility rate, and total fertility rate - and use the terms consistently. So I made this annotated table: familyinequality.wordpress.com/2025/10/03/l...

The acting CDC director has now approved ACIP recs allowing anyone 6 months+ to receive an updated Covid-19 shot after discussing w/ their provider. If you are on the fence about getting an updated shot, read my in-depth take on the evidence we've accumulated on these vaccines. #publichealth

🚨 The Economist has been telling you for years that polygamy causes civil war by locking men out of marriage. A new article with @rebeccasear.bsky.social and @anthrolog.bsky.social explains that the demography of marriage markets doesn't actually work that way. 🧵 www.pnas.org/doi/10.1073/...

If one man marries two women, another man must go unmarried, right? No. Demography matters. If sex ratios are skewed towards women, then polygyny can exist alongside universal marriage for men (who want to marry women). If only more people understood demography 😊

The HPV vaccine is doing what had been promised. 17 years after it became available, HPV infections decreased significantly in vaccinated people and unvaccinated people because of herd immunity. buff.ly/WvjQ1BS h/t @boghuma.bsky.social #medsky #pedsky 🛟🧪
