As the European Union mulls a digital Covid certificate, it has clarified that the aim of the certificate is to increase ease of movement inside the EU. It is not a prerequisite for travel. Individual member states will have the option to accept other vaccines also which may not have been authorised by the WHO, such as Covishield. India will take up the issue of approval of the Covishield vaccine by the European Medicines Agency on the margins of the G20 meeting in Italy on Tuesday.
