The African Union has criticised an EU decision not to include Covishield, a version of AstraZeneca’s coronavirus vaccine used by the global COVAX facility, on a list of approved vaccines for a digital certificate meant to ease travel in the bloc. Reuters reports that Covishield is produced by the Serum Institute of India and has been distributed to African nations as part of the COVAX initiative to give poor and developing countries access to Covid-19 vaccines.
