This market will resolve to "Yes" if the CDC issues a Level 3 (“Reconsider Nonessential Travel”) Travel Health Notice for any disease by December 31, 2025, 11:59 PM ET. Otherwise, this market will resolve to "No".

A Level 3 notice listed for any amount of time during this market’s timeframe will suffice for a "Yes" resolution. 

The primary resolution source for this market will be the CDC’s official Travel Health Notices page (https://wwwnc.cdc.gov/travel/notices); however, a consensus of credible reporting will also be used.

A reduction in the scope of recommended recipients, or the removal of a recommendation for a specific type of vaccine for the listed disease (e.g. CDC removal of the recommendation for the live oral polio vaccine in 2022) without fully eliminating the recommendation will not be sufficient for a "Yes" resolution.

The resolution source will be official CDC announcements and guidance published on the CDC website (see: https://www.cdc.gov/acip-recs/hcp/vaccine-specific/).

This market will resolve to "Yes" if any vaccine intended for humans and inoculating against HKU5-CoV-2  receives full FDA approval between February 20, and December 31, 2025, 11:59 PM ET. Otherwise, this market will resolve to "No".

Otherwise, this market will resolve to “No”. 

Withdrawing approval solely due to seasonality, low demand, or an emergency ending will not be sufficient for a "Yes" resolution. Similarly, a reduction in the scope of approved recipients, without fully eliminating the approval will not be sufficient for a "Yes" resolution."

The resolution source will be official FDA announcements and guidance published on the FDA website (see: https://www.cdc.gov/acip-recs/hcp/vaccine-specific/).

Will RFK end any vaccine approvals by December 31?

Note that advance estimates will be considered. For example, if upon release, the advance estimate for Q2 2025 was negative, and the Q1 2025's most recent, up-to-date estimate was also negative, this market would resolve to "Yes". If on December 31, 2025 the latest estimate for quarterly GDP in Q3 2025 was negative, this market will stay open until the Advance estimate of Q4 2025 is published, at which point it will resolve to "Yes" if Q4 2025 was negative or if the NBER declares a recession by then.

The resolution source will be the official announcements from the NBER and the BEA’s estimate of seasonally adjusted annualized percent change in quarterly US real GDP from previous quarters as released by the Bureau of Economic Analysis (BEA), https://www.bea.gov/data/gdp/gross-domestic-product

If such an earthquake has not appeared on the resolution source by that date, another credible resolution source will be used.

This market will resolve to “Yes” if either of the following conditions is met:

1.  The seasonally adjusted annualized percent change in quarterly U.S. real GDP from the previous quarter is less than 0.0 for two consecutive quarters between Q2 2025 and Q4 2026 (inclusive), as reported by the Bureau of Economic Analysis (BEA). 

2.  The National Bureau of Economic Research (NBER) publicly announces that a recession has occurred in the United States, at any point during 2025 or 2026, with the announcement made by the time the BEA releases the advance estimate for Q4 2026.

Note that advance estimates will be considered. For example, if upon release, the advance estimate for Q3 2025 was negative, and the Q2 2025's most recent, up-to-date estimate was also negative, this market would resolve to "Yes".

Accidents, radiological dispersal devices (bombs that spread radioactive material using conventional explosives such as "dirty bombs"), or actions by third parties will not count toward this market's resolution.

Tests not explicitly claimed by US may still qualify if a clear consensus of credible reporting attributes the nuclear detonation to US. For example, an unclaimed nuclear test analogous to the 1979 "Vela Incident" would count if credible reporting attributes it to the US.
