Clade 2.3.4.4b but not historical clade 1 HA replicating RNA vaccine protects against bovine H5N1 challenge in mice by David W. Hawman, Thomas Tipih, Eddie Hodge, E. Taylor Stone, Nikole Warner, Natalie McCarthy, Brian Granger, Kimberly Meade-White, Shanna Leventhal, Kiara Hatzakis, Stephanie Park, Karen Gaffney, Kyle Rosenke, Jesse H. Erasmus, Heinz Feldmann

“…Abstract The ongoing circulation of influenza A H5N1 in the United States has raised concerns of a pandemic caused by highly pathogenic avian influenza. Although the United States has stockpiled and is prepared to produce millions of vaccine doses to address an H5N1 pandemic, currently circulating H5N1 viruses contain multiple mutations within the immunodominant head domain of hemagglutinin (HA) compared to the antigens used in stockpiled vaccines. …”

Zoonotic diseases awareness and food safety practices among livestock farmers in Nepal by Deepak Subedi, Alok Dhakal, Sumit Jyoti, Sanjay Paudel, Sanjay Paudel, Ganesh Ranabhat, Ananda Tiwari, Ahmad I. Al-Mustapha, Ahmad I. Al-Mustapha, Ahmad I. Al-Mustapha

“…Two-thirds of pig farmers (67%; n = 12/18) were aware of zoonotic transmission of swine flu, and more than half of the poultry (58%; 50/86) farmers knew about zoonotic avian influenza. The majority of the farmers who had dogs (83%) and cats (89.4%) in their homes or farms knew that rabies can be transmitted to humans from dogs or cats. …”

Probing the functional constraints of influenza A virus NEP by deep mutational scanning by Qi Wen Teo, Yiquan Wang, Huibin Lv, Michael S. Oade, Kevin J. Mao, Timothy J.C. Tan, Yang Wei Huan, Joel Rivera-Cardona, Evan K. Shao, Danbi Choi, Chaoyang Wang, Zahra Tavakoli Dargani, Christopher B. Brooke, Aartjan J.W. te Velthuis, Nicholas C. Wu

“…Additional experiments show that N-terminal domain mutations affect viral transcription and replication dynamics, host cellular responses, and mammalian adaptation of avian influenza virus. Overall, our study not only advances the functional understanding of NEP but also provides insights into its evolutionary constraints.…”

Ocular infections in international travelers by Francesca F. Norman, Julio J. González-López, Diego Gayoso-Cantero, Marta Vicente-Antolin, Maria-Dolores Corbacho-Loarte, Rogelio López-Vélez, Marta González-Sanz

“…Main findings: Common respiratory tract viral infections may cause ocular complications in travelers, human influenza viruses have been associated with conjunctivitis and emerging avian influenza subtypes may also affect the eye. Vector-borne viral infections may affect travelers, usually with systemic symptoms, but eye disease may be the first presenting feature. …”
