    Formalin-inactivated phase I vaccine (PIV) offers greater protection against Coxiella burnetii than phase II vaccine (PIIV) in murine models.

  • 2

    PIV induces earlier and sustained phase I-specific IgM and IgG responses compared to PIIV, highlighting differences in immunogenicity.

  • 3

    PIV vaccination leads to prolonged neutrophil activation in the spleen, while PIIV induces a transient neutrophil response.

  • 4

    Neutrophil depletion in PIV-vaccinated mice significantly reduces the vaccine's protective efficacy against C. burnetii.

  • 5

    The study reveals that sustained neutrophil activation is crucial for PIV-mediated protective immunity against C. burnetii infection.
