Comparative Analysis of New Influenza Vaccines and COVID-Influenza Combination Vaccine
Contagion Live Annual immunizations against SARS-CoV-2 and influenza viruses are crucial for public health, addressing the evolving nature of these viruses. Aiming to enhance influenza vaccines for older adults, researchers have focused on eliciting broad immune responses against different flu strains, particularly H3N2, while avoiding antigenic changes related to egg adaptation. Findings from the study […]

HPAI circulating in US dairy cattle since 2023?
Watt Poultry Analysis suggests that highly pathogenic avian influenza may have entered the U.S. dairy herd late last year, as one in five milk samples in the country test positive for HPAI virus fragments. While it may be a truism to say that a virus must be present to be detected, simply reporting virus’ detection […]

Do Our Flu Antivirals Work on H5N1?
MedPage Today With avian influenza A (H5N1) infecting more mammals than ever before — including U.S. dairy cattleopens in a new tab or window — infectious disease experts are paying close attention to whether current influenza antivirals would be effective should H5N1 adapt to humans. All influenza viruses have extremely similar internal mechanisms for reproduction, William Schaffner, […]

How bird flu virus fragments get into milk sold in stores, and what the spread of H5N1 in cows means for the dairy industry and milk drinkers
The Conversation The discovery of fragments of avian flu virus in milk sold in U.S. stores, including in about 20% of samples in initial testing across the country, suggests that the H5N1 virus may be more widespread in dairy cattle than previously realized. The Food and Drug Administration, which announced the early results from its nationally representative sampling on […]
