This smells distinctly like collider bias and/or selection bias and/or regression to the mean... You simply can't select teen prodigies, and world class athletes rom databases, and go run regressions without serious consideration of the selection process!

Imagine you lived in the 18th century. Smallpox kills 1 in 3 cases. Yet you can’t culture pathogens, don’t know germ theory, and have no idea what a virus is. How would you invent a vaccine? In a new episode of HARD DRUGS, we trace the history of vaccines!

Pathoplexus is growing not only in terms of new sequences, but also integrating into the larger ecosystem of pathogen surveillance by joining WHO's IPSN and expanding membership. This is the way a pathogen sequence database should work! (Lessons learned from GISAID/SARS-CoV-2...)

I want to spell this out in case the implications aren't clear: This means all public tools/webapps of GISAID data (all the ones you've been used to seeing thru the pandemic, as far as we can tell) are prohibited. The file allowed this. Cut that - cut off all tools the public & others were using.

Nextstrain's daily-updated tree of SARS-CoV-2 genomes was my gateway into the world of viral phylogenetics in early 2020, and Nextstrain's beautiful interactive tree display is crucial to making

Closing these public analyses puts the world more in the dark and concretely harms surveillance as it becomes more difficult for variant spotters to contribute to global situational awareness. 4/5

On Oct 1, 2025, GISAID informed us that they had ended updates to the flat file of SARS-CoV-2 genomic sequences and associated metadata that we had used to update Nextstrain analyses since Feb 2020. GISAID's stated rationale was that their "resources are limited". 1/5

The science is, in fact, clear. Good studies [1] consistently show a weak association between tylenol & autism. Those studies are very careful to say they can't establish whether this is causal. A huge Swedish study used a clever sibling design to address this, and showed zero causal effect [2].
