Nchabeleng principal investigator, Soshanguve Block L Clinic , Dr. The efficacy of the rotavirus vaccine against rotavirus gastroenteritis of any severity is presented in in the Supplementary Appendix. More than 90 percent of these deaths occurred in developing countries. . Sauerman; from GlaxoSmithKline — A. Studies of these vaccines have demonstrated their safety and efficacy among children in every region of the world. Healthy infants were randomly assigned in a 1:1:1 ratio to receive two doses of vaccine in addition to one dose of placebo or three doses of vaccine — the pooled vaccine group — or three doses of placebo at 6, 10, and 14 weeks of age.

Vaccination is the best way to protect children from rotavirus and the deadly dehydrating diarrhea that it can cause. Infants who had received the complete vaccination course and had entered the efficacy surveillance period, which began 2 weeks after the last dose, were included in the prespecified primary efficacy analysis per-protocol efficacy cohort. Efficacy against all-cause severe gastroenteritis was 30. No other potential conflict of interest relevant to this article was reported. Nevertheless, the preventable burden of disease in low-income settings is potentially much greater.

In South Africa, healthy infants, 5 to 10 weeks of age, were enrolled from October 2005 through January 2006 and from November 2006 through early February 2007, before the anticipated rotavirus seasons of 2006 and 2007, respectively. In 2009, the World Health Organization recommended that all countries include rotavirus vaccines in their national immunization programs. Continuing surveillance of the safety of the vaccines as they are introduced into more countries will be important. Statistical analysis The primary study analysis compared findings from the pooled vaccine group with those from the placebo group. Six of the seven countries with the highest mortality due to rotavirus diarrhea are located in Africa. A total of 4417 infants were included in the primary efficacy analysis — 2974 in the pooled vaccine group and 1443 in the placebo group. The parents or legal representatives of the infants participating in the study provided written informed consent before the initiation of any study-related procedures.

The overall efficacy of the rotavirus vaccine in preventing episodes of severe rotavirus gastroenteritis 61. No restrictions were imposed on the breast-feeding of infants around the time of vaccination. Suryakiran for statistical analysis; Y. The vaccine showed efficacy against severe rotavirus gastroenteritis both in infants who received two doses of vaccine 58. Currently, two vaccines against the disease are globally available, four vaccines are available in national markets only, and several more are in development. Rotavirus types G2, G8, and G9 have circulated for several years in both countries, whereas rotavirus type G12 has been reported more recently. With access to 12 years of pre-vaccination and 5 years of post-vaccination data, the analysis predicted that 1 extra dose of rotavirus vaccine at 9-months of age would provide only a modest 5-16 percent reduction in overall case incidence over the first 3 years.

Venter; Rota Consortium — Dr. Potential side effects include loss of appetite, fever, and diarrhea. Rotavirus Rotavirus is the most common cause of severe diarrheal disease in children worldwide. Active surveillance for all gastroenteritis episodes was conducted by members of the study staff through weekly visits to parents or guardians to collect diary cards and through the collection of data from health clinics that served the study populations. In this study, the diversity of the circulating strains was striking. Rehydration therapy is an important part of treating dehydration due to diarrheal diseases, including rotavirus.

Despite the lower point estimate for efficacy, the number of severe cases of rotavirus gastroenteritis prevented was greater in Malawi than in South Africa 6. Other study contributors were: Aisleen Bennett, Naor Bar-Zeev and Khuzwayo Jere from the Malawi-Liverpool-Wellcome Trust Clinical Research Programme at the University of Malawi; Benjamin Lopman from the Rollins School of Public Health at Emory University; Joseph Lewnard from the University of California, Berkeley School of Public Health; and Umesh Parashar from the Centers for Disease Control and Prevention. These data are consistent with an integrated analysis of previous efficacy trials of the rotavirus vaccine, which indicates that the rotavirus vaccine provides protection against severe rotavirus gastroenteritis caused by G1 and non-G1 strains. Related diseases Diarrheal disease is a leading cause of death in children in developing countries. Methods We conducted a randomized, placebo-controlled, multicenter trial in South Africa 3166 infants; 64. As a result, vaccination provides only partial protection and tends to delay cases among vaccinated infants to the second year of life, according to the study.
