#Pedantic mode on

While you're updating this section, you probably should include the broader term

'immunization' although in the last year the terms have become nearly interchangeable.

    Thanks for the clarifications.



    As I understand it, the URN identifies a vaccination event, a test

    event, or a recovery event. The URN itself does not associate the

    assertion with a particular person (there is no "person" construct built

    into the URN). For instance, if I get a test, that test is assigned a

    URN. If I receive documentation (physical or digital) of the URN that's

    been assigned and I present such documentation, the assocation comes

    from the fact that I'm the one presenting the documentation. Some other

    system (say, a medical records system) could formally associate that URN

    with some other identifier for me as a person within a given nation or

    region, but that kind of association is out of scope for the URN definition.



    If this is correct, I think we could slightly adjust the wording to make

    it fully clear.



    Peter
