Alongside the RSV‑B model, hVIVO has developed a new human metapneumovirus (hMPV) challenge model. hMPV is a close relative of RSV and is increasingly recognised as a significant respiratory pathogen. As developers move toward combination respiratory vaccines, validated challenge models for each component become essential. The hMPV model has shown strong infection rates and robust symptoms, making it a valuable addition to the respiratory challenge platform. Development of a PIV model has now also begun.
Together, the RSV‑A, RSV‑B, and hMPV models provide a comprehensive suite of tools for evaluating next‑generation vaccines and therapeutics. They enable precise, early‑phase assessment of each component in a controlled environment, reducing uncertainty and accelerating development.
Looking Ahead
The future of respiratory virus research will rely increasingly on tools that can generate high‑quality data early in development. Human challenge trials are uniquely positioned to meet this need. They offer a controlled setting for understanding infection dynamics, identifying correlates of protection, and evaluating the performance of vaccines and antivirals long before large field trials are possible.
