Answer given by Mr Reynders on behalf of the European Commission
According to the EU Digital COVID Certificate Regulation, where Member States accept proof of vaccination in order to waive travel restrictions, they are obliged to accept certificates for EU-authorised vaccines. Member States may also waive restrictions for holders of certificates indicating other vaccines.
For vaccines administered by third countries, it is necessary to determine if they correspond to an EU-authorised vaccine. The Commission supported discussions in the Health Security Committee on this issue, and has published an overview of vaccines administered by third countries, for which most EU Member States would waive travel restrictions, and a list of sublicensed vaccines, for which several Member States waive travel restrictions as they consider them as corresponding to the vaccines that had received EU approval.
To help coordinate travel requirements across the EU, the Council, upon proposal of the Commission, updated the recommendation on the coordination of free movement restrictions, which includes,, for example, standard validity periods for tests.
Passenger Locator Forms (PLFs) are national contact-tracing tools, supporting the implementation of Decision 1082/2013 on serious cross-border health threats.
The EU PLF exchange platform facilitates exchange of health data between national authorities, based on their national PLF systems. Decisions based on information contained in PLFs are the sole responsibility of Member States.
