Because according to Reuters, the European Commission on Tuesday agreed to new rules that will make the EU’s COVID vaccine travel passport (what they call a “travel certificate”) will be valid for nine months after the completion of the “primary vaccination schedule” – which right now only includes the first two doses.

The new rules will be binding for all 27 member states starting Feb. 1.

The decision, made by the bloc’s governing commission, which has purview over issues related to intra-bloc travel, comes just as Germany’s Robert Koch Institute, the primary source of public health policy, recommended on Tuesday that “maximum contact restrictions” should be imposed, starting immediately, to combat a looming tide of infections caused by this latest winter wave (to which the new omicron variant is now contributing).

Also, it’s worth pointing out that the nine month timeline leaves the door open for the EU to require boosters, potentially as often as every six or nine months.
