Exposing a virus's hiding place reveals new potential vaccine

Researchers have identified a potential vaccine to prevent respiratory infections in humans by understanding how the human metapneumovirus (HMPV) hides from the immune system. A mutated form of HMPV was created, which triggers a stronger innate immune response, effectively preventing infection and promoting an adaptive immune response.
