This trial is active, not recruiting.
|Sponsor||National Institute of Pediatrics, Mexico|
|Collaborator||Centro Nacional para la Salud de la Infancia y la Adolescencia|
|Start date||November 2013|
|End date||October 2016|
|Trial size||1498 participants|
|Trial identifier||NCT02193061, Rota/CeNSIA|
Assess the immunological behavior of children from 2 months of age that receive one out of seven anti-rotavirus vaccination programs: Group 1 (routine schedule with two doses of RV1 - Rotarix plus sterile water) and Group 2 (routine schedule with three doses of RV5 - RotaTeq) versus Group 3 (one dose of monovalent vaccine followed by two doses of pentavalent vaccine), Group 4 (one dose of pentavalent vaccine followed by two doses of monovalent vaccine), Group 5 (two doses of pentavalent vaccine followed by a dose of monovalent vaccine), Group 6 (one dose of pentavalent vaccine followed by a dose of monovalent vaccine and a dose of pentavalent vaccine), and Group 7 (a dose of monovalent vaccine followed by a dose of pentavalent vaccine and a dose of monovalent vaccine) in children from Mexico City.
- To describe number and features of acute diarrheal disease (ADD) due to rotavirus displayed in the seven prevention schedules.
- To describe the adverse events temporarily associated with the seven prevention schedules.
Hypotheses The seroconversion percentages and geometric mean titers (GMT) of anti-rotavirus antibodies from Groups 3, 4, 5, 6 and 7 are not inferior to the seroconversion percentages and the GMTs induced in subjects that received the routine vaccination schedules with two doses of the monovalent vaccine and three doses of the pentavalent vaccine (Groups 1 and 2).
