This market will resolve to "Yes" if the U.S. Food and Drug Administration (FDA) grants full or conditional approval for Merck’s biologics license application (BLA) for clesrovimab (MK‑1654) as a preventive treatment for respiratory syncytial virus (RSV) in infants by June 17, 2025, 11:59 PM ET. Otherwise, this market will resolve to "No". This market will immediately resolve to "No" if the FDA issues a Complete Response Letter (CRL), explicitly declines to approve the application. Conditional approvals may include post-marketing requirements or commitments and still qualify. The primary resolution source will be official information from the FDA, however a consensus of credible reporting may also be used.
