This Wednesday the European Commission has signaled its support for the possibility of imposing PCR tests on all people who move from one EU country to another, even if they are vaccinated, this would include non-EU visitors traveling from outside the EU. The measure has already been adopted by members-states such as Portugal, France, and Ireland. With France being the latest to impose a negative test carried out at most 48 hours before to all travelers, who are vaccinated or not.
"A week ago we did not know anything about omicron," said Von der Leyen. The alert came on Thursday from South Africa. "And on Friday at midnight, the 27 EU countries were already coordinated," the President of the Commission celebrated.
The coordination resulted in the cancellation of all flights from South Africa and six other African countries. But internally, the response was mixed. Portugal was the first country to tighten the conditions for travelers from other EU countries. And since December 1, Portugal requires the presentation of a negative test from passengers arriving by plane, even if they have a COVID certificate that proves that they have received the complete vaccine.
The guidelines approved this Wednesday by the Commission state that “based on the latest scientific evidence available and in line with the precautionary principle, to respond to the current risk of the omicron variant, the requirement of a PCR test prior to arrival can be considered a suitable instrument ”. The document specifies that the PCR requirement is appropriate "in particular for travel to the EU, as well as for travel within the EU."
