Rules summary

If any vaccines have their FDA approval or authorization revoked, or voluntarily withdrawn, for reasons relating to health, safety, or efficacy before Jan 1, 2026, then the market resolves to Yes. Outcome verified from Food and Drug Administration.

Merely withdrawing approval because of seasonality, low demand, or an emergency ending is not sufficient to resolve the Contract.
