    The test-negative design (TND) is a case-control study method used to estimate vaccine effectiveness during outbreaks.

  • 2

    The global mpox outbreak declared in 2022 highlighted the need for effective study designs to analyze risk factors and vaccine efficacy.

  • 3

    Stigma surrounding mpox affects healthcare-seeking behavior, challenging the TND's assumption of similar behavior between cases and controls.

  • 4

    Differential diagnoses of mpox complicate data collection, as conditions with similar symptoms may not be included in epidemiologic databases.

  • 5

    Potential solutions to improve TND validity in mpox studies include addressing selection bias and enhancing data collection methods.
