RFK Jr. fact checked: Physician reveals what Kennedy gets wrong on vaccine safety Jake Scott says the evidence on vaccine safety is clear and publicly available

The updated US SARS-CoV-2 genomics shows a sharp increase in the NB.1.8.1 variant, and to a lesser extent XFG (combine w/ XFC).
It remains to be seen how much these, especially NB.1.8.1, can lead to a significant rise in cases here, as was seen in Asia.

A polystyrene ball that has coloured flags inserted into it representing the opinions of the public on participation in human challenge studies. The ball has been designed to look like a large virus.

We're making viruses from public opinions! At #GERF2025 we're asking the public if they would take part in a human challenge study: green for yes, red for no, and blue for maybe. The mix of opinions is fascinating and it's clear there's a hunger to know more! 🧪@imperialinfect.bsky.social, @cepi.net

A group of researchers presenting the 'Would you get sick for science stand?' at the Great Exhibition Road Festival 2025. The stand is populated by various banners, posters and activities to engage the public on human challenge studies.

We had an amazing first day at the @ExRdFestival! We talked to loads of people about human challenge studies and the work of MUSICC, IMMPROVE, GERMINATE, CHANTS, Hic-Vac, and INFLAMMAGE. We're back today in South Kensington, London. Come on by! #GERF2025 @imperialinfect.bsky.social @ovg.ox.ac.uk 🧪

My co-EIC Florian Krammer wrote this commentary in Vaccine on the need for next generation flu vaccines to have a NA component (the N in H5N1 or H3N2).

It’s a smart idea & safeguards against bad matches to HA & other subtypes that share N1 or N2.

Next-generation seasonal influenza virus vaccines need a neuraminidase component

"...a balanced immune response to HA and NA would have benefits since anti-NA immunity could act as safety net in years when the HA component of the vaccine is mismatched (and vice versa)."

The threat of avian influenza H5N1 looms over global biodiversity - Nature Reviews Biodiversity The highly pathogenic avian influenza H5N1 is an emerging and unexpected threat to many wild animal species, which has implications for ecological processes, ecosystem services and conservation of threatened species. International collaboration and information-sharing is essential for surveillance, early diagnosis and the provision of financial and technical instruments to enable worldwide actions.

A brief history of human infections with H5Ny avian influenza viruses - great to see a review not only focussed on H5N1, but also consider those H5N8 and H5N6 infections.

This Year Influenza Came Back to Remind Us It's Not Messing Around If it seems like pretty much everyone you know either has the flu or is recovering from it, it’s because we’re in the middle of the worst flu season in over a decade. Take a look at this figure, from ...

Quite the flu season we're having. Here are some thoughts. I finish up by wondering why we'd reduce CDC workforce at a time like this -- just unfathomably short-sighted.

CDC cuts expected to devastate Epidemic Intelligence Service, a ‘crown jewel’ of public health Members of the CDC's Epidemic Intelligence Service were warned Friday that many of them were about to be fired

Doing the unthinkable: The deep cuts to the #CDC's workforce today are expected to decimate the Epidemic Intelligence Service, a program that has trained public health rapid responders for decades.
Envy of the world. Poof!

Four lessons COVID taught us about the immune system In the midst of pandemic upheaval, researchers have gained fundamental insights about how the body fends off infections.

Some learnings about our immune system from Covid @nature.com
—importance of T cells (not just neutralizing antibodies)
—key role of interferons, the first line of defense
—hybrid immunity
—underpinnings of Long Covid
