E.U. proposal would allow vaccinated American tourists by the end of June
“We need a single certificate which is valid in all member states, which can get rid of this cacophony of different measures that prevent people from moving freely, that discourage people from mounting to move around the union,” said Juan Fernando López Aguilar, a Spanish member of European Parliament who is leading that body’s negotiations of the draft rules about covid-19 travel documents. Many policymakers shy away from calling them vaccine passports, since they don’t actually require that the bearers be vaccinated. The people working on them have dubbed them “green certificates” instead.
