Emergency Use Authorization

Emergency Use Authorization (EUA) is a mechanism that allows regulatory agencies to authorize the use of medical products, like vaccines or treatments, during public health emergencies before full FDA approval. It enables faster access to potentially life-saving interventions while still evaluating their safety and effectiveness. EUA is granted based on available scientific evidence, balancing the urgent need for rapid response with the need to protect public health. It is not the same as full approval but provides a legal pathway to deploy crucial medical tools during crises.
