    What does "princeps" mean here for a clinical trial? First? Pivotal?
    They are talking about the 'princeps" trials for a new vaccine.

    Hi. I assume "essai princeps" is a French term. If so, I would translate it as "first trial".
    Hope it helps.

    Asuming that "essai princeps" is in French language, I guess "pivotal assay".

    Just bumped into this old thread, belatedly, but for future needs: "seminal" is the word :)

    It it's a clinical trial that's being described, "seminal" almost certainly does not work. I'm assuming that it is what American medical researchers call the Phase 1 trial. That is, the first of at least three trials required before a new drug or technique can be approved for clinical use.

    Note that "seminal" means that the thing thus described is not only the first or original, but also had notable influence on later works.
