Workers' Compensation; vaccine-related accidents or injuries shall be compensable.

SB 2409 makes workplace vaccine injuries compensable under Mississippi's workers' compensation law. It directly affects employees required by employers to get vaccines for work or hiring, establishing a presumption that vaccine-related injuries arise from employment unless proven otherwise. The bill also amends unemployment rules to state that being fired for refusing a mandatory workplace vaccine does not disqualify someone from unemployment benefits. Key mechanisms include the presumption of compensability for vaccine injuries and the explicit inclusion of vaccine refusal as "good cause" for unemployment eligibility. These changes aim to clarify protections for workers facing vaccine mandates.
