Objective: The present investigation examined the main and interactive effects of coronavirus disease 2019 (COVID-19)-related medical vulnerability (CMV; the number of medical conditions with potential to elevate COVID-19 risk) and first responder status (emergency medical services roles vs non-emergency medical services roles) on mental health symptoms.

Methods: A national sample of 189 first responders completed an online survey between June and August 2020. Hierarchal linear regression analyses were conducted and included the following covariates: years served as a first responder, COVID-19 exposure, and trauma load.
