Regulatory approvals

What does emergency use authorization mean?


WHO’s Emergency Use Listing (EUL) is a procedure for assessing and listing vaccines with the ultimate aim of making them more readily available to people affected by a public health emergency. It opens the door for countries that do not have robust regulatory systems of their own and need to rely on WHO’s robust review process to expedite their own regulatory approval processes to import and administer the vaccine. It also enables UNICEF and the Pan-American Health Organization to procure the vaccine for distribution to countries in need.

WHO has already listed several COVID-19 vaccines for emergency use. WHO and partners are working night and day to evaluate other vaccines that have reached safety and efficacy standards. We encourage even more developers to come forward for review and assessment. It’s vitally important that we secure the critical supply needed to serve all countries around the world and stem the pandemic.

WHO Emergency Use Listing:

  • aims to expedite access to safe and quality assured vaccines
  • enables UN procurement and supports Member States decisions
  • involves stringent assessment of clinical trial, manufacturing and regulatory data
