In 2019, NIAID proposed an ambitious scientific network focused on pandemic preparedness, research, and response - the "CREID Network".
Ten centers kicked off just as the pandemic was taking off, playing critical roles throughout.
We were just notified the whole network is terminated.
Reason? 👇

Everything in this article rings true. The vagueness of this EO and the proposed ramifications are unsettling. Any GoF regulations must be clear and explicit, otherwise all infectious disease research could be in limbo. The consequence? Public health. This is disappointing and, sadly, unsurprising.
There are still a lot of questions swirling around the executive order on "dangerous gain-of-function" research that Trump signed yesterday. I've written up for @science.org what we know so far and what it might mean for infectious disease research.

It is worth paying close attention to the new bill "Dangerous Viral Gain of Function Research Moratorium Act" introduced by Senator Roger Marshall.
If enacted, it will effectively stop all of virological research, including for vaccines.

This is major #H5N1 news: While, so far, dairy cows in the US were infected by genotype B3.13, genotype D1.1 was found in Nevada via the national milk testing strategy.
If confirmed that it's not a bird intrusion into a milk tank, this means that there has been a new spillover into dairy cows.

Extremely interesting and equally concerning. Definitley eager to see these sequences…🦠🐄
4 dairy herds in Nevada recently diagnosed with #H5N1 #birdflu were infected with a different version of the virus than has been spreading in cows elsewhere. Evidence of a second (at a minimum) spillover points to the challenge of stopping spread, experts say. www.statnews.com/2025/02/05/u...
