This market will resolve to "Yes" if the CDC has completely ended its recommendation for the listed vaccine, meaning it no longer recommends it for any category of individuals by December 31, 2025, 11:59 PM ET. Otherwise, this market will resolve to “No”.

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/).
