EUA (Emergency Use Authorization)

Emergency Use Authorization (EUA) is a mechanism that allows health authorities, like the U.S. FDA, to permit the use of medical products—such as vaccines or treatments—before they receive full approval in urgent situations, like public health emergencies. This process is used when there is adequate evidence suggesting that the product is effective and the benefits outweigh any risks. EUA helps expedite access to essential medical solutions during crises, such as pandemics, while ensuring that safety standards are still considered.
