The rotavirus vaccine was withdrawn by its manufacturer, Wyeth Ayerst Laboratories, after only one year on the market.
Notes on verification
Confirmed by CDC MMWR, NEJM, and academic sources; RotaShield was withdrawn ~14 months after licensure due to intussusception risk. Minor imprecision in 'one year' framing and exact subsidiary name (Wyeth-Ayerst vs Wyeth Lederle). [tier=gold indep_score=1.0 clusters=3 claim_tier=notable]
