More Info

An Emergency Use Authorization (EUA) makes medical treatments and vaccines available when the public’s health is at risk, such as during a pandemic.

Under an EUA, medicines and vaccines are still being tested but the approval process is fast-tracked in order to make interventions available more quickly.

An EUA applies to the USA only. Other countries have different rules and regulations.
