摘要：What is already known about this topic? Before the introduction of rotavirus vaccine in the United States in 2006, rotavirus infection was the leading cause of severe gastroenteritis among U.S. children. What is added by this report? Implementation of the U.S. rotavirus vaccination program reduced the annual proportion of positive rotavirus tests, reduced peak rotavirus activity, and shortened the duration of the rotavirus season. Biennial seasonal patterns that emerged after vaccine introduction have continued with alternating years of low and high rotavirus activity. What are the implications for public health practice? Ongoing efforts to improve coverage and on-time vaccination can help maximize the public health impact of rotavirus vaccination.
