Brief 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.
Detailed Description:
Vaccination is the best way to prevent severe rotavirus disease and the deadly, dehydrating diarrhea that it causes. However, given only moderate efficacy in the first year of life and a possible further decline in immunity, it is considered a top priority by public health experts to evaluate the possible value of a "booster" dose of rotavirus vaccine in low income countries to confer longer duration of protection into the second year of life when disease burden continues to be high.
This study is an open-label, individual-randomized, parallel-group, comparative immunogenicity trial. Participating infants randomized to Group A will receive one dose each of measles vaccine (MV), yellow fever vaccine (YFV), and meningitis conjugate vaccine (PsA-TT-5μg) at 9 months of age, and infants randomized to Group B will receive one dose each of MV, YFV, PsA-TT-5μg, and PRV at 9 months of age.
The study will simultaneously evaluate two primary objectives, one for noninferiority of the response to MV given with PRV (co-primary objective 1) and one for noninferiority of the response to YFV given with PRV (co-primary objective 2).
Secondary objectives of the study were the following:
1. To evaluate the non-inferiority of the immune response 3 months post-vaccination (as sero-conversion) to MV given with PRV (Group B) to that given without PRV (Group A).
2. To compare the immune response (as geometric mean titers \[GMTs\]) to YFV given with PRV (Group B) to that given without PRV (Group A).
3. To evaluate the non-inferiority of the immune response (as sero-response) to PsA-TT-5μg given with PRV (Group B) compared to that given without PRV (Group A).
4. To compare the immune response (as GMTs) to PsA-TT-5μg given with PRV (Group B) to that given without PRV (Group A).
5. To evaluate the superiority of the immune response (as sero-response and geometric mean concentrations \[GMCs\]) to a supplemental dose of PRV given at 9 months of age with local EPI vaccines (Group B) compared no supplemental dose (Group A).
6. To describe the safety profile of study vaccination with PRV.
