Merck (MRK) Stock Today – December 8, 2025: Pipeline Bets, Cidara Deal and Vaccine Policy Risks
Merck & Co., Inc. is back in the spotlight. As of the afternoon of December 8, 2025, Merck shares trade around $98–99, down about 1% on the day and modestly below their recent 52‑week high of $105.84 reached in late November. That pullback comes after a powerful rebound from a May low near $76, driven by excitement over new cardiovascular and respiratory drugs, plus a $9.2 billion flu‑drug acquisition — even as investors remain focused on the looming 2028 patent cliff for Keytruda and fresh regulatory headwinds.Finviz+2Reuters+2
