Despite the global spread of the mpox virus, the long-term durability and breadth of infection-induced immunity are not fully understood. Here, the authors analyze MPXV-specific immune responses up to 18 months post-infection, revealing robust cellular immunity and cross-neutralization among orthopoxviruses, which inform reinfection risks and vaccine development strategies.
