The European Union is preparing the ground for vaccine passports. A common approach for mutual recognition of vaccination documentation is of the “utmost importance”, the Commission said today, adding that it wants “an appropriate trust framework” to be agreed upon by the end of January — “to allow Member States’ certificates to be rapidly useable in health systems across the EU and beyond”.

“Vaccination certificates allow for a clear record of each individual’s vaccination history, to ensure the right medical follow-up as well as the monitoring of possible adverse effects,” it writes, adding that: “A common EU approach to trusted, reliable and verifiable certificates would allow people to use their records in other Member States. Though it is premature to envisage the use of vaccine certificates for other purposes than health protection, an EU approach may facilitate other cross-border applications of such certificates in the future.”
