Older adults might be more resistant to bird flu infections than children, Penn research finds - Those who were exposed to seasonal flu viruses that circulated prior to 1968 were found to be more likely to have antibodies that bind to the H5N1 avian flu virus.

Bird flu virus found surviving in certain cheeses 🧀🦠: 4.4% of Americans drink raw milk at least once a year, 1.6% drank it often, and 1.6% ate raw-milk cheeses. The study found that the bird flu virus (H5N1) can still survive in raw-milk cheese, even after 120 days of aging at 39 °F (3.8 °C).

Scientists excited about nasal spray vaccine for bird flu that generated ‘strong immune response’ in rodents. Traditional flu vaccines by injection have 40-60% chance vaccinated person gets infected and passes flu virus on. Nasal vaccines stop virus from establishing itself and prevent transmission.

🐦 Over 84% of dead black vultures tested by UGA researchers were positive for highly pathogenic avian influenza (H5N1). The study examined 134 vultures from seven states in 2022-2023.

scavenging behavior may be sustaining bird flu transmission year-round, raising concerns about potential mutations and increased risks to other species, including humans.

🦅 Black vultures play a key ecological role, and their decline due to bird flu can lead to more carcasses, potentially increasing disease spread among people, wildlife, and domestic animals.

💡 A silver lining is that about half of infected vultures survive, developing antibodies and some protection against future outbreaks, offering a conservation perspective for the species.
