COVID-19 vaccines: research and development

The European Medicines Agency (EMA) is interacting with developers of potential COVID-19 vaccines to enable its distribution in the European Union (EU) as soon as possible.

EMA is providing guidance to assist developers of potential COVID-19 vaccines to prepare for eventual applications for marketing authorisation. 

The outcome of any consultation or advice from EMA is not binding on developers.

Information on ongoing clinical trials for COVID-19 vaccines in the European Economic Area (EEA) is available in the EU Clinical Trials Register (EU CTR):

• EU CTR: COVID-19 vaccines

Users can find information on:

• phase II to phase IV adult clinical trials for COVID-19 vaccines where the investigator sites are in the EEA;
• any clinical trials in children with investigator sites in the EU and any trials that form part of a paediatric investigation plan, including those where the investigator sites are outside the EU.

Phase I clinical trials conducted solely in adults are not made publicly available in the EU CTR.

For more information on the EU CTR and how clinical trials are authorised and overseen in the EEA, see:
