  1. 369. Advancements in Chikungunya Virus Vaccines: Emerging Innovations and Future Directions
    Jonas Schmidt-Chanasit

    Vaccines & Immunology
    Oral presentation

    Chikungunya virus (CHIKV) is re-emerging as a One Health threat at the human-vector-climate interface. WHO and ECDC data show major resurgence in 2025-2026, with large outbreaks in the Indian Ocean and the Americas and substantial autochthonous transmission in Europe, including 788 confirmed locally acquired cases in France and 384 in Italy in 2025. European evidence, indicates that once...

  2. 506. Zoonotic MPXV Clades Outpace Human-adapted Strain in Driving Disease and Shedding in a Nasal Respiratory-Infection Macaque model
    Prof. Julia R. Port (Laboratory of Transmission Immunology, Helmholtz Center for Infection Research, Braunschweig, Germany)

    Vaccines & Immunology
    Oral presentation

    MPXV comparative biology after mucosal exposure remains unclear. We compared clades Ia (Zaire and Republic of Congo isolates), IIa, and IIb in a cynomolgus macaque respiratory infection model to assess disease, viral shedding, and immune responses. Mucosal infection caused milder, more localized disease than high-dose aerosol or intravenous models. Clade Ia (Zaire) and IIa produced stronger...

  3. 508. Impacts of Respiratory Mucus on Influenza Virus Stability, Transmission, and Immune Interactions
    Ms Jailene Castillo

    Vaccines & Immunology
    Oral presentation

    The remarkable zoonotic competence of Influenza A virus (IAV) warrants dedicated One Health vigilance. As the cause of four disruptive pandemics in the last century, pervasiveness into previously unaffected regions, and elevated incidence of human and animal infections, IAV continues to circulate across multiple host species. Most of the research on IAV entry has investigated interactions...

  4. 441. Differential innate immune activation following Puumala virus infection of human or reservoir host cells
    Ms Marie Demuth (Centre for Biological Threats and Special Pathogens (ZBS), Robert Koch-Institute, Berlin, Germany), Dr Daniel Bourquain (Centre for Biological Threats and Special Pathogens (ZBS), Robert Koch-Institute, Berlin, Germany)
    10/7/26, 10:30 AM
    Vaccines & Immunology
    Oral presentation

    Hantaviruses maintain persistent and asymptomatic infections in their mammalian reservoir hosts but can cause severe disease when transmitted to humans. In Europe, Puumala virus (PUUV) is the most important cause of human hantavirus infections. To investigate if hantavirus disease in humans is driven by an overreactive immune response, we aimed to compare PUUV replication and innate immune...
