The Nordic Council of Ministers’ eHealth group assigned the Nordic eHealth standardizations group with the task of developing a common Nordic description and/or approach to the basic interoperability elements of the eHealth Network (eHN) “guidelines on verifiable vaccination certificates - basic interoperability elements” . The key findings were that the Nordic countries participated in the development of the European solution for the Covid- 19 certificate. The solution was successful, and no separate Nordic guideline was needed. Nordic collaboration and coordination in EU’s standardization work is valuable both to jointly influence the decision making and to maximize the benefit for Nordic countries.
