FILE - This undated file photo issued by the University of Oxford on Monday, Nov. 23, 2020, shows of vial of coronavirus vaccine developed by AstraZeneca and Oxford University, in Oxford, England.
The Medicines and Healthcare Products Regulatory Agency, which recommended the AstraZeneca vaccine for emergency use, did not endorse one vaccine over the other.
Britain’s action likely means the World Health Organization could soon clear the AstraZeneca vaccine for use in a global effort to help poor countries, called COVAX.
The European Medicines Agency said it is still assessing the AstraZeneca vaccine and has asked the company for more information on its quality, safety and effectiveness.
In addition to the Serum Institute, AstraZeneca has deals with vaccine makers in Brazil, South Africa and China.
