Direct and Indirect Effects of Rotavirus Vaccination Upon Childhood Hospitalizations in 3 US Counties, 2006–2009
Clin Infect Dis. (2011) 53(3): 245-253 doi:10.1093/cid/cir307

Active, population-based surveillance from 2006-2009 observed dramatic decreases in rotavirus hospitalization rates among children in 3 US counties. In 2008, reductions were prominent among both vaccine eligible age groups and older, largely unvaccinated children; the latter likely resulting from indirect protection.
