I've added links to the briefing documents.
At this point, I haven't read it, but table 3 (page 18) of the J&J briefing seems to indicate (roughly) 60% effectiveness against severe/critical COVID at 14 days.
I believe this is a different yardstick than for the Moderna & Pfizer which I think were (roughly) 95% against getting COVID and 100% against severe/critical disease.
