From EU News in late December:
“Today, the Commission adopted rules relating to the EU Digital COVID Certificate, establishing a binding acceptance period of 9 months (precisely 270 days) of vaccination certificates for the purposes of intra-EU travel. A clear and uniform acceptance period for vaccination certificates will guarantee that travel measures continue to be coordinated, as called for by the European Council following its latest meeting of 16 December 2021. The new rules will ensure restrictions are based on the best available scientific evidence as well as objective criteria. Continued coordination is essential for the functioning of the Single Market and it will provide clarity for EU citizens in the exercise of their right to free movement.”
It was the stated aim from years back now that this “passport” come into being, in the US as well over time. Once done, it will be difficult to resist. Ergo resist all must.
