Source: Reuters, {Excerpt} (...) Tests confirmed the H7N6 subtype of bird flu at a rural chicken farm in the Otago region, Biosecurity New Zealand said in a statement. It is different to the H5N1 strain that has spread globally and raised fears of human transmission. (...) our testing shows it is unrelated to a H7 strain that was identified in Australia earlier this year," Biosecurity New…

#Influenza A Virus #H7 #nanobody recognizes a conserved immunodominant epitope on #hemagglutinin head and confers heterosubtypic #protection

Source: BioRxIV, AbstractInfluenza remains a persistent global health challenge, largely due to the virus continuous antigenic drift and shift, which impede the development of a universal vaccine. To address this, the identification of broadly neutralizing antibodies and their epitopes is crucial. Nanobodies, with their unique…

In summary, our findings highlight the critical role of Neu5Gc in affecting the host range and interspecies transmission dynamics of H7 viruses among avian species.

We conducted a serological #survey for binding #antibodies to flu A & B in goats (n=452) & sheep (n=329) in #Pakistan & found high seropositive rates for HA of avian influenza A #H5 (23.9-34.0%), #H7 (13.9-37.1%), & #H9 (17.0-34.7%). In contrast, there were low levels of seropositivity against HA of human & swine pandemic #H1N1/pdm09 (0.9-1.8%) in goats and against swine H3 (0.6%) in sheep.

We collected pooled fecal swabs from 225 farms and tested the samples for the AIV matrix gene followed by #H5, #H7, and #H9 subtyping using rRT-PCR. We found that 39.6% of chicken farms were AIV positive, with 13% and 14% being positive for subtypes H5 and H9, respectively.

The #US government will pay #Moderna $176 million to develop an #mRNA #vaccine targeting #H5 and #H7 varieties of #pandemic #influenza—an award given as the highly #pathogenic #birdflu #virus #H5N1 continues to spread widely among US dairy #cattle.
The funding flows through #BARDA, the Biomedical Advanced Research and Development Authority, as part of a new Rapid Response Partnership Vehicle (#RRPV) Consortium. Phase 3 trial anticipated to begin in 2025. https://arstechnica.com/science/2024/07/us-prepares-for-bird-flu-pandemic-with-176m-moderna-vaccine-deal/

Multivalent vaccine was evaluated in both naïve & pre-immune mice to mimic immunity in humans. Both HA head- & stem-directed Abs levels were high in vaccinated mice. Little to no #lung #injury was observed in lungs of vaxed mice following challenge. Vaccine provided 4-mos-long protection vs clade 2.3.4.4 #H5N6 virus.
