We don’t have many of these, because viruses evolve too fast, infections are diagnosed too slow, & unlike bacteria, viruses can be so different that there aren’t many broad spectrum antibiotics. The AViDD centers were funded to develop antivirals for potential pandemic viruses.
Like the ASAP center based at Sloan Kettering, which was using AI structural analysis to predict & test molecules targeting 3 virus families: coronaviruses, flaviviruses (dengue, yellow fever, Zika, West Nile, HCV), & picornaviruses (polio, EV-D68, FMDV).
Or the AC/DC center at Emory, developing nucleoside analogs & polymerase inhibitors against CoVs, flavis, picornas, paramyxoviruses (Nipah, Hendra, measles, RSV), & togaviruses (Chikungunya, VEEV/WEEV/EEEV). They had 4 drugs to test & were screening more.
At Scripps there was CAMPP, focused on CoVs, flavis, & hemorrhagic fever viruses (filoviruses: Ebola, Marburg; bunyaviruses: SFTSV; arenaviruses: Lassa). They were advancing promising oral candidates as well as finding drugs with new mechanisms of action.
I was fortunate enough to be invited to speak at a pandemic preparedness seminar hosted by CAMPP last month, where I got to hear from a number of colleagues doing amazing antiviral discovery work in CAMPP & other AViDD centers. And all anyone could talk about was H5N1.
In fact, I was on my way to the symposium getting calls from reporters about another hospitalized H5N1 patient as well as new pre immune studies just out. Flu antivirals don’t work very well & can develop resistance quickly, so new antivirals are crucial for flu pandemics.
In my talk, I went over how slashing & burning government personnel, data, & funding will devastate our ability to prevent & respond to an H5N1 pandemic. Now CAMPP & the AViDD program can be added to my slide on the destruction of American readiness.
Also lost is this AViDD center at Stanford focused on multiple drugs targeting all RNA viruses via a combo of mechanisms: small molecule inhibitors, antisense, & protein drugs. Combination therapies are much less likely to select for resistance mutations.
The MAVDA center sought novel drug targets in CoVs, flaviviruses, & alphaviruses like CHIKV. Charlie Rice won the Nobel prize in 2021 for work that led to drugs that cured HCV. I’ve known him since I was a postdoc. He’s brilliant & also a very kind person
The Midwest AViDD Center at U of Minnesota was doing a lot of sophisticated high throughput screening to find novel antivirals for SARS2 and also hemorrhagic arenaviruses, filoviruses, & flaviviruses. Also a training/outreach component for effective use.
This center at UCSF is led by world class viral proteomics experts (also shout to Regina, SK, where Nevan is from, so I’ll forgive him for being a Niners fan). They were developing novel targeted drugs for 8 viral families! All gone now.
This goes out to all the lab leakers who have baselessly accused Ralph Baric of making SARS-CoV-2. No. His READDI AViDD Center was making new drugs to treat emerging CoVs & other viruses. He was trying to prevent or end pandemics, not start them.
Finally this AViDD center at UTMB was targeting proteases and polymerases to develop new drugs against coronaviruses, flaviviruses, & henipaviruses (Hendra & Nipah). All emerging viruses we need better drugs for.
These AViDD centers were an investment in our future, developing medicines that we could use to prevent or respond to viral pandemic threats. They employed hundreds of people & contributed to the economy as well as our toolbox of countermeasures.
And that’s no longer a priority.
How can the government claim it is making America healthy again when it’s literally shutting down research that would keep Americans healthy from pandemic viral pathogens? We need more ways to treat viral diseases, not less. We need more antiviral drugs.
And how does it benefit the American taxpayer to put hundreds of Americans out of work? I’m not an economist but I’m pretty sure that swelling the ranks of the unemployed is not a good way to boost the economy.
Cutting programs like AViDD makes us less prosperous, less innovative, less competent, less prepared, and less safe. We will have fewer countermeasures to fight emerging viruses. We are falling behind.
This is not just a funding cut. It’s an attack on our well-being.
We aren’t helpless here. Congress must step in and insist that appropriations are applied as they have decided. DOGE & Trump do not legally have the right to can programs that Congress paid for. So call your representatives & demand they step up.
AViDD invested our tax dollars in the future health of the American people. I reject a regime that attacks science, puts Americans out of work, & endangers us all on the whims of idiot billionaires with authoritarian ambitions. We should demand the return on our investment.

Have I ever mentioned how surreal it is to be an Editor-in-Chief of a journal called Vaccine right now?
It’s pretty wild, at least by typical academic journal editorial office standards.science.org/content/articl…
Last Nov, the FDA’s top vaccine regulator forced FDA scientists to withdraw a paper from review because it showed that COVID vaccines work for all ages. Papers in Vaccine have been cited selectively by RFK Jr to mislead the public about vaccines. Now Vaccine is in the news again
I will always be grateful for opportunities to emphasize the integrity of our editorial & peer review practices & to invite authors to submit their work—especially if it contributes to a larger scientific debate or has a major impact on our field, public health, or society.
As the accursed ostrich situation continues to get simultaneously more stupid and gravely serious, I decided to write up a very long analysis of many of the key issues. Bottom line: so long as this flock lives, it is a threat to Canada's national security. 🧵
5 months ago I was scrolling & came across some tweets from @sisuvanhell that was my first exposure to the far-right extremist ostrich convoyers. They accused CFIA of sending "murder drones" to covertly cull their flock of ostriches after a H5N1 outbreak open.substack.com/pub/rasmussenr…
In Dec 2024, Universal Ostrich Farms had a confirmed H5N1 outbreak on their remote farm in BC. They did not report to CFIA as required by law. They lost 69 ostriches. CFIA found out anyway & tested 2 dead ostriches. They were positive. They issued a depopulation (cull) order.
This is interesting. The BC ostrich farmers have consistently misrepresented the “scientific research” they were conducting, but it seems they also may have not been entirely truthful about their ostrich meat, oil, & leather business, as well 👇🏻
The ostrich farm claims they are a scientific research facility to study ostrich antibodies. Birds have antibodies in their egg yolks & ostrich eggs are huge, so you can get a lot of antibodies from them. The farmers implied they were studying antibodies to COVID & flu.
But there’s nothing to show that’s true. They’ve never published a paper on the research or shared data/results. There’s a difference between doing research & producing antibodies to sell. According to court documents, they were producing eggs for the latter purpose.
I am always happy to talk to reporters like Nancy MacDonald @globeandmail covering the BC bird flu ostrich story with objectivity & a focus on the evidence.
I hope this clarifies why I think the cull of these birds should proceed whether they are tested or not. Short thread 🧵
The thing people need to realize is that, although the ostriches were infected 10 mo ago, they still pose a health risk & a HUGE economic risk. If CFIA spares them, Canada will violate trade agreements, jeopardizing the entire $2B poultry export market.
CFIA is responsible for ensuring the safety & health of Canadian people & animals by regulating agriculture & food. A big part of the agricultural mandate is to ensure compliance with trade partners' import requirements, to maintain trade. inspection.canada.ca/en/animal-heal…
I'm not uncomfortable with an interview. I don't wish to contribute to anti-government extremist propaganda that imposes the will of a few on Canada's health, food security, economy, & $2B poultry export market. I believe in upholding the law.
1. You can test these ostriches for antibodies. To do it reliably you need to do either a microneutralization or a hemagglutinin inhibition (HAI) assay. These require a high containment lab & trained personnel with HPTA security clearance because they use live virus.
Not many labs in Canada can do these tests. You can't do ELISAs due to cross-reactivity across other flu subtypes. Many overlapping subtypes circulate in birds (H5Nx; HxN1) & humans (H1N1). So you can't just measure antibody binding by ELISA, you must do HAI or microneuts.
