The market defines clear and specific conditions for resolution. It requires full approval by the U.S. FDA for a human vaccine targeting Hantavirus (explicitly covering HPS and HFRS) on or before December 31, 2026, at 11:59 PM ET. The primary resolution source is the official FDA licensed vaccines database, with credible media consensus as an auxiliary source. Note that the rules require full FDA approval rather than emergency use authorization.
