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. #IDsky 🧪 www.science.org/content/arti...

Exciting job opportunities! Two postdoc positions are available in the Fodor Lab at @dunnschool.bsky.social to study influenza virus transcription, genome replication, nuclear export and assembly. More info: my.corehr.com/pls/uoxrecru...

I admit I’m very biased towards the new acting director of NIAID. Jeff is a phenomenal mentor and researcher, and an overall stellar human. I look forward to see how he will advocate for NIAID researchers in the interim 🦠 www.science.org/content/arti...

This doesn't look good, folks www.nature.com/articles/d41...

This bill could dismantle virology research. Please follow this informative thread to see why this is concerning for the field as a whole. It also makes me worried about what jobs I’ll be able to find post-graduation. Also, hate seeing influenza listed first this document…

Kristian G. Andersen@kgandersen.bsky.social · last yr.

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. www.marshall.senate.gov/wp-content/u... 🧵👇

Enough is enough. It’s gut-wrenching to see this happen in a place that’s been my scientific ‘home’ for seven years. www.science.org/content/arti...

🚨BREAKING. From a program officer at the National Science Foundation, a list of keywords that can cause a grant to be pulled. I will be sharing screenshots of these keywords along with a decision tree. Please share widely. This is a crisis for academic freedom & science.

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.

USDA milk testing shows different strain of H5N1 bird flu in Nevada dairy herds

The USDA said four Nevada dairy herds were infected with an H5N1 bird flu strain that has circulated in wild birds, making prospects for containment in cows appear dim.

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...

Wendy Barclay and I will soon be recruiting a postdoc to work on a virology project investigating the evolution of swine influenza viruses and how this impacts future pandemic potential. Job will be based at Imperial's South Kensington campus. Drop me a DM/email for more details.
