The FDA approved a rotavirus vaccine in fall 1998, but by July 1999 the CDC recommended it not be used due to increased cases of intussusception among vaccinated children.
Notes on verification
Confirmed by CDC MMWR archives, PubMed-indexed reports, and CDC press release. Minor discrepancy: FDA approval was August 31, 1998 (late summer), described as 'fall' in the claim, but this doesn't affect substance. [tier=bronze indep_score=0.539 clusters=2 claim_tier=notable]
