Meta-analysis of the effectiveness of pentavalent live oral vaccine for the prevention of severe forms of rotavirus gastroenteritis in children
Abstract
Rotavirus infection is ubiquitously distributed and represents a global public health problem. Some studies showed that vaccination with pentavalent oral live vaccine was effective in prevention of severe forms of rotavirus gastroenteritis among children up to 3 years of age. Previous randomized placebo-controlled studies assessing this issue were repeatedly conducted. However, due to the features of the epidemiology of pediatric rotavirus infection in Russia, a metaanalysis was conducted in the risk group — children under the age of 3 years by administering a full vaccination course for a single vaccine registered in the Russian Federation. A search was performed by two independent reviewers covering 1994 to February 2019, without restrictions on language, in five databases on medical and biological publications: Russian Science Citation Index, PubMed, Web of Science, MEDLINE, Scopus, and in contents of thematic journals and bibliographic lists. The meta-analysis included multicenter randomized controlled trials comparing the efficacy of placebo and completed full vaccination course with pentavalent live oral rotavirus vaccine in children under 3 years of age. The primary endpoint of the study was the incidence of severe gastroenteritis among children according to the Vesikari evaluation system. Data processing and generation of forest-plots to evaluate summarized results were carried out by the RevMan 5.3 free software distributed on the Cochrane Community website. The…
