“Obviously, in any case, we will not be able to fully return to normal life in the summer of 2021, some restrictive measures will have to be preserved,” RIA Novosti quoted him as saying.

According to him, to ensure the freedom of movement of citizens within the European Union, the community needs a "reliable tool", which will be a certificate.

Also, the European Commissioner said that the technical work on preparing the launch of the certificates "is going well."

According to him, "it is necessary to launch the certificates by the summer."

Earlier, the representative of the World Health Organization in Russia, Melita Vujnovich, said that the introduction of "vaccination passports" would lead to an increase in inequality in the world.
