An Evaluation of the Immune Response to Pentavalent Rotavirus Vaccine After a Supplemental Dose Given at 9 Months of Age With Local EPI Vaccines in Mali
In Brief
A Phase 4 clinical trial evaluating pentavalent rotavirus vaccine (PRV), measles vaccine (MV), and 2 other interventions for Diarrhea Rotavirus. Completed, enrolled 600 participants across 1 site.
Detailed Summary
This study is an evaluation of the immune response to pentavalent rotavirus vaccine (PRV) after an additional fourth dose is given at 9 months of age with local World Health Organization (WHO) Expanded Programme on Immunization (EPI) vaccines in Mali.
Study Details
Timeline
Interventions
Each two-ml dose contains 5 live human-bovine reassortant rotaviruses with a minimum of 2.0 - 2.8 x 106 infectious units (IU) per reassortant, depending on the serotype, and not greater than 116 x 106 IU per aggregate dose. Each vaccine dose contains sucrose, sodium citrate, sodium phosphate monobasic monohydrate, sodium hydroxide, polysorbate 80, cell culture media, and trace amounts of fetal bovine serum. RotaTeq contains no preservatives. RotaTeq is a pale yellow clear liquid that may have a pink tint. This vaccine was administered orally.
A lyophilized vaccine in a pack containing one vial plus one ampoule of sterile water for injection. After reconstitution, each 0.5 ml/dose of MV contains active substances not less than 1000 units of 50% cell culture infectious doses (CCID50) of MV. Measles Vaccine Live Attenuated virus is propagated on Human Diploid Cells. This MV is currently part of the local EPI program in Mali. This vaccine was administered subcutaneously to the right deltoid.
A freeze-dried live attenuated yellow fever virus of the 17D strain for injection. After reconstitution, one dose (0.5 ml) contains active substances not less than 1000 units of 50% lethal doses (LD50) of yellow fever virus. This YFV is currently part of the local EPI program in Mali. This vaccine was administered intramuscularly to the left deltoid.
A meningococcal A vaccine, with meningococcal A polysaccharide (PsA) conjugated to the carrier protein, tetanus toxoid (TT). After reconstitution, one dose (0.5 ml) contains 5μg meningococcal A polysaccharide and 5-16 μg tetanus toxoid as a carrier protein. PsA-TT-5μg was considered experimental at the initiation of this study, but received approval from the WHO for infants on 30 December 2014. For all participants enrolled January 1st, 2015 or later, PsA-TT-5μg was not included in Group A or Group B, due to its December 2014 expiration date. This vaccine was administered intramuscularly to the right thigh.
