The Impact

Rotavirus is responsible for 26% of diarrheal deaths in Latin America and the Caribbean. Haiti introduced the monovalent rotavirus vaccine in April 2014. The objective of this analysis is to describe the impact of the rotavirus vaccine on hospitalizations among Haitian children younger than 5 years old during the first 5 years after introduction. This analysis includes all children with diarrhea who were enrolled as part of a sentinel surveillance system at two hospitals from May 2013 to April 2019. We compare the proportion of rotavirus-positive specimens in each post-vaccine introduction year to the pre-vaccine period. To account for the potential dilution of the proportion of rotavirus-positive specimens from a waning cholera outbreak, we also analyzed annual trends in the absolute number of positive stools, fit a two-component finite-mixture model to the negative specimens, and fit a negative binomial time series model to the pre-vaccine rotavirus-positive specimens to predict the number of rotavirus diarrhea hospital admissions in the absence of rotavirus vaccination. The overall percentage of rotavirus-positive specimens declined by 22% the first year after introduction, increased by 17% the second year, and declined by 33% to 50% the subsequent 3 years. All sensitivity analyses confirmed an overall decline. We observed a clear annual rotavirus seasonality before and after vaccine introduction, with the greatest activity in December through April, and a biennial pattern, with high sharp peaks and flatter longer periods of increased rotavirus activity in alternating years, consistent with suboptimal vaccination coverage. Overall, our study shows evidence that the introduction of the rotavirus vaccine reduced the burden of severe rotavirus diarrhea.

Vaccine Surveillance

Diarrhea is a notable global health problem in several developing countries, especially in children. Prior to the introduction of the rotavirus vaccination program in Ghana, a surveillance study was conducted to investigate the prevalence of the disease caused by rotavirus in children. In this report, we re-used archival stool samples from the pre-vaccine surveillance study to provide information on prevalence of enterotoxigenic Escherichia coli in Ghanaian children. Re-analysis of the stool samples revealed co-infection of enterotoxigenic E. coli and rotavirus in 2% of the children whose samples were selected for this study. As Ghana is approaching 10 years post-implementation of the rotavirus vaccination program, the preliminary data presented in this report are a vital reference for subsequent studies aimed at ascertaining the effect of the vaccine on both rotavirus and enterotoxigenic E. coli.

Abstract Background Since 2006, more than 100 countries have introduced rotavirus vaccine into their immunization programs. We reviewed published data on relative reductions of rotavirus hospitalizations, acute gastroenteritis (AGE) hospitalizations, and AGE deaths among children &lt;5 years old. Methods Articles published from January 1, 2006 to December 31, 2019 with at least 12 months of data before and after rotavirus vaccine introduction were included. Relative reductions were abstracted into a standardized form. Descriptive statistics are presented as medians and interquartile ranges (IQRs). Results We reviewed 1827 total records and included 105 articles from 49 countries. Among children &lt;5 years old, there was a median reduction of 59% (IQR, 46–74) in rotavirus hospitalizations, 36% (IQR, 23–47) in AGE hospitalizations, and 36% (IQR, 28–46) AGE mortality. Reductions were larger in countries with low child mortality, among younger age groups, and in countries with higher coverage. The median percentage of specimens that tested positive for rotavirus among children &lt;5 years old hospitalized for diarrhea was 40% (IQR, 28–45) before rotavirus vaccine introduction and 20% (IQR, 20–20) 4 years after introduction. Conclusions Overall, we found sustained impact on rotavirus and AGE hospitalizations and deaths. These results should encourage countries still considering rotavirus vaccine implementation.
