Protection against gastroenteritis in US households with children who received rotavirus vaccine.

We used Truven Health Marketscan claims database (2008-2011) to compare gastroenteritis rates during January-June among households whose child had received rotavirus vaccine with those whose child did not receive vaccine. Statistically significantly lower rates of hospitalization with a rotavirus gastroenteritis or unspecified-gastroenteritis discharge code occurred in vaccinated households among persons 20-29 years and females 20-29 years (2008/2009), and males 30-39 years (2009/2010). Lower emergency department gastroenteritis rates occurred in vaccinated households among females 20-29 years (2009/2010) and individuals 5-19 years (2010/2011). These data suggest rotavirus vaccination of infants provides indirect protection against moderate-to-severe rotavirus disease in young parents and older siblings.
