The EU council, made up of member states has agreed a new recommendation, that countries should base their travel rules on an individual case rather than the region they are travelling from. The recommendation is set to come into force on February 1st, but it is non-binding.
That would mean those with an EU Covid certificate, which proves vaccination, recovery or a negative test would be allowed to travel freely within the EU or Schengen zone without the need for extra tests or quarantine, even if they were coming from a country with high Covid infection rates. But this refers only to travel, and not to the domestic health or vaccine passes that many EU countries now require to access venues such as bars.
