Over half of U.S. milk now being tested for H5N1

Dr. Keith Poulsen with the Wisconsin Veterinary Diagnostic Laboratory tells Brownfield progress is being made towards USDA’s goal of testing all raw milk for the virus. “Over 50% of the cows that produce the milk for the United States are part of the surveilance program now. We’re hoping for another large number of states to be announced this Wednesday (1/8/25). The big ones, California, Pennsylvania, New York are part of this program along with many others.

No need to provide an avian flu vaccine for humans yet, expert says

Dr. Shira Doron, an epidemiologist and chief infection control officer for Tufts Medicine in Boston, said the minor spread of the H5N1 among humans – and no reported instances of human-to-human transmission – makes any widespread administration of a vaccine premature right now.

“There are also many logistical issues that would be associated with deployment of vaccine to farm workers – language barrier, undocumented status, compliance – so that is not the plan at this time, “ Doron said Friday morning during an Infectious Diseases Society of America teleconference.

Dr. Julio Figeroua, LSU Health chief of infectious diseases and a professor at Louisiana State University’s medical school in New Orleans, also took part in the IDSA teleconference. There have been no secondary avian flu cases related to the patient in Louisiana who died, he said.

Excuses. It is proven that dairy cattle and poultry workers are at risk for H5N1 transmission. One person with backyard poultry contact died. link

There are many examples of vaccines being used when there is an occupational hazard despite language spoken or country of origin. For example,

Hepatitis B https://www.osha.gov/sites/default/f...s/bbfact05.pdf
Flu,
Vaccinia,
Yellow fever,
Some medicines when traveling for work to areas of risk, like anti-malaria drugs
-------------------------------

The real truth is that the gov. wants to hoard the H5N1 vaccines and/or complimentary vaccines in case there is a serious human-to-human outbreak. There will not be enough vaccines so let the hoarding begin.

This is the same manipulation as done for the masks at the beginning of the covid pandemic. An official said masks wouldn't work and later he admitted he said that because there were not enough respirators for healthcare workers in the US and the feds wanted to control the market.

So be forewarned. As this site said in the covid pandemic - do not depend on the government to "save" you.

Mild H5N1 cases have been perplexing scientists – now they might have an answer

The variant circulating in America appears to be less lethal and could be triggering different responses from the immune system

Since bird flu began spreading in the US, one question has been puzzling scientists: why are the farm workers who are catching it only suffering mild illness?

Of the 66 people infected in America this year, the overwhelming majority – more than 98 per cent – have suffered only from conjunctivitis, tiredness, and a sore throat.

Remarkably, all but one case – a Louisiana man in his mid-60s who succumbed to the illness earlier this month – have recovered.

A new study published in the journal Emerging Microbes & Infectious Diseases has found that older and newer strains of H5N1 could be triggering different responses from the immune system.

Conclusions

In summary, this study provides a characterization of virus replication and host responses to infection in human alveolar epithelium between a contemporary clade 2.3.4.4b human HPAI H5N1 isolate and the highly virulent A/Vietnam/1203/2004 virus. Further studies are warranted to understand how these viruses interact with the innate immune system, particularly regarding differential ISG and proinflammatory cytokine induction, and how this affects pathogenesis in vivo. Nonetheless, our results indicate that the clade 2.3.4.4b HPAI viruses currently circulating in cattle will likely exhibit reduced human disease severity compared with historic HPAI viruses but should be closely monitored for changes that may influence pathogenicity or transmissibility.
