Coronavirus Disease 2019 (COVID-19) EUA Information

FDA expects the COVID-19 public health emergency (PHE) declared by the Department of Health and Human Services under the Public Health Service Act to expire on May 11, 2023. The ending of the COVID-19 PHE will not impact FDA’s ability to authorize medical countermeasures for emergency use. Existing COVID-19 EUAs will remain in effect, and the agency may continue to issue new EUAs if the situation meets the criteria to do so.
