Outcome Measures

Primary Outcomes (1)

  • Innate immune training.

    Innate immune training, detected as fold-changes in cytokine production capacity of innate immune cells for cytokines such as IL-1β, IL-6, IL-10, TNF-α and IFN-γ, following pro-inflammatory stimulation from inclusion to 4 months post-inclusion.

    From inclusion to 4 months post-inclusion.
