I'm fortunate to live in a state with a high-quality health department that provides information based on science. For those who don't I recommend Canadian canada.ca/en/public-health.h… or UK gov.uk/government/organisati… advice.

US health agencies like CDC and NIH and FDA remain full of dedicated and exceptional scientists and health professionals doing the right thing for public health. But this example shows they can be overruled by an exceptionally unqualified secretary of HHS.

I just joined APHA bit.ly/3tPy1KU -- a strong advocate for public health right now. Encourage others to do the same!

Excited to share a new preprint led by Indra Gonzalez Ojeda on a new tool to improve pangenome calling in bacteria, CLARC. biorxiv.org/content/10.1101/… . Passing output of Roary for S. pneumoniae populations through this tool reduces accessory genome > 30%, resolves other puzzles

My profound thought for today: Jargon and buzzwords are opposites. Jargon are words almost no one uses that have precise meaning. Buzzwords are words everyone uses that have little meaning. Clarity is avoiding both.

Trump’s Project 2025 explained hilariously, terrifyingly, and perfectly.
Trump’s Project 2025 will end America as we know it and turn it into the White Christian Nationalist version of Afghanistan.

Just out w @chrisbboyer academic.oup.com/aje/advance… Emulating target trials of postexposure vaccines using observational data. Spurred by great collab with @nycHealthy on mpox vaccines, but applies to any postexposure intervention on an infection to reduce risk of bad outcomes.

Qiu et al. developed a weighting system to adjust pneumococcal invasive disease data to represent the carriage population, allowing the NFDS mechanism to predict strain proportions in carriage in post-PCV13 era. @XuetingQ @mlipsitch @BillHanage @CCDD_HSPH journals.asm.org/doi/10.1128…

The @nytimes should not have this even in the Opinion section. No responsible statistician uses 13 predictors (actually many more because many of the predictors have variable thresholds) to predict 30 data points ("120 years of presidential elections"). Clickbait pure and simple. nytimes.com/2024/09/05/opini…

This book was a behemoth for the editors I am sure- and years in the making. But I’m so honored to part of the critical effort on “Principles and Practice of Emergency Research Response” with some incredible thinkers & doers in our field including Dr Fauci, @DrTedros, @doctorsoumya, Dr Collins and so many others I respect. And some I’ve had the great fortune to work with over the years.
