1. A #flu update:
#CDC has learned of 8 more pediatric flu deaths, bringing this season's total to 123. That number will continue to rise; deaths are often reported on a delay.
Case in point: 2024-25's peds death total rose by 1 last week with a death from Feb '25 just reported.
~85% were not vaxed.— Helen Branswell 🇨🇦 (@helenbranswell.bsky.social) March 27, 2026 at 11:45 AM
2. Some good news:
#Flu season is kinda over. I say kinda coz there's still flu around. But when the percentage of medical visits that are for flu-like illness falls below 3.1% — and it did last week — we're considered to be out of flu season.
At this point, flu B is causing much of the illness.— Helen Branswell 🇨🇦 (@helenbranswell.bsky.social) March 27, 2026 at 11:45 AM
3. Conditions vary across the country, but most parts are out of the worst of the #flu season now. Last week's map (left) shows few states still engrossed. Compare that to a month ago. (right)
#CDC estimates about 23,000 people died from flu this season.

“It’s no longer Tony Fauci’s NIH.”
Fauci was the director of NIAID, not NIH. Jay knows that, but he was pandering to the crowd. He loves the right-wing adulation. 2/10
But then Jay follows up by mentioning that NIH discoveries that “saved millions of lives” and “turned HIV into a manageable condition”.
It’s true. NIAID supported research on COVID vaccines, and antiretroviral therapies – UNDER TONY FAUCI. 3/10
“we must build a biomedical innovation research enterprise that moves faster, reaches further, and delivers real results for patients.”
The fuck does he mean “build”?! We have that, but barely, as Jay ended grants, fired workers, and destroyed training programs for young scientists. 4/10
“identify the scientists and fund those great ideas and then the institutions compete for the institutional funds.”
This was about separating the competition for scientific grants from a cost-based competition for research facilities. Here’s one reason why this is Bhattshit crazy… 5/10
Research depends infrastructure. If the project needs a high-tech imaging facility or drug screening facility, those must be in place when the grants are funded. If scientists wait until their universities get facilities grants or are recruited to a place with one, they will lose valuable time. 6/10
He switches over to repurposing of drugs. It’s a reasonable idea (but not original to him) to ask if drugs with known safety profiles can be used to treat diseases other than the ones they were developed for. And then he says… 7/10
“Faster therapeutic development… can actually help solve the budget deficit.”
What crazy train takes him from drug repurposing to solving the deficit? I mean, how many drugs will have to be repurposed to help get us out of the $1.8T (FY25) hole? Again, pandering to a MAGA crowd. 8/10
He pivots to clinical trial ethics, saying “. We have to do this the American way with respect for human subjects .”
His boss tried to fund an unethical trial in Guinea Bissau and his WIFE lied about FDA approval to recruit for a serology study. So he can fuck off with his new found ethics. 9/10
He closes, to applause, with “committing ourselves to scientific rigor, getting rid of DEI and all the other nonsense.”
Nonsense is eliminating research on health disparities and pediatric cancer, and awarding $500M to your buddies to research antiquated vaccine development strategies. 10/10
🧪This is important.

2 years ago now the world learned US dairy cows were being infected with #H5N1 #birdflu, raising concern the virus would find a new route to move from animals to humans. Cow infections seem to have slowed & many questions remain, @cohenjon.bsky.social reports. www.science.org/content/arti…
— Helen Branswell 🇨🇦 (@helenbranswell.bsky.social) March 30, 2026 at 11:18 AM
… Even if H5N1 were eliminated from U.S. dairy herds, it could jump back in, scientists warn. The virus now circulating in cows, a genotype called B3.13, stems from a single introduction into cattle that likely occurred in the fall of 2023. But results from milk testing showed that another genotype, D1.1, jumped into cattle from birds on three occasions, quickly dying out each time. An unknown variant seems to have made the jump in the Netherlands, where researchers recently found antibodies against H5N1 in cows, indicating they were infected at some point.
Some researchers say vaccination is the best way to bring the current outbreak to an end and prevent future ones. “The goal has to be to use a vaccine in conjunction with testing and all the other things in place right now to really try to stamp this thing out,” says viral immunologist Scott Hensley of the University of Pennsylvania.
Hensley’s team has one of several promising vaccine candidates under development. Earlier this month, the group posted results from a trial of a messenger RNA (mRNA) vaccine that triggers production of B3.13’s hemagglutinin surface protein. The study found animals that were vaccinated and then exposed to the virus had reduced disease and produced just as much milk, with 1000-fold lower viral levels in it.
Whether USDA will allow use of H5N1 vaccines in dairy cattle—and whether the price will be attractive to farmers—is a huge question. H5N1 vaccines exist for poultry, but USDA has never given them a green light, mainly because of concerns that vaccination could harm the export market. And because of widespread suspicion of mRNA vaccines in the wake of the COVID-19 pandemic, many states are considering banning their use for livestock as well. “It’s amazing to me,” Hensley says.
Pereira sees the limited spread of the virus right now as a lucky grace period that should be used to speed vaccine development and use every existing measure to prevent a resurgence. “Instead of, ‘Oh, no, it’s OK now, we can ignore it,’ we should realize we’ve been given time,” he says. “Let’s use it wisely.”
