A coronavirus vaccine developed by Oxford University and AstraZeneca Plc was approved by the European Commission on 29 January, only hours after the European Medicines Agency gave the product a positive opinion. The approval is the third for a Covid-19 vaccine in the EU. The other two are vaccines developed by Moderna Inc, approved on 6 January, and a vaccine developed by BioNTech SE and Pfizer Inc, approved on 21 December 2020. Authorisation of the AstraZeneca vaccine was based on data showing an efficacy rate of around 60%.
