Trial Outcomes & Findings for The Interaction Between Measles and DTP Vaccination (NCT NCT02710045)

NCT ID: NCT02710045

Last Updated: 2019-01-28

Results Overview

The IFN-gamma:IL-4 cytokine ratio in plasma samples taken 4 weeks after vaccination measured by multiplex assay using the Bio-Plex 200 Suspension Array system. Ratio compared between the 3 intervention groups with the hypothesis that the MV+DTP group will have a higher ratio than the other 2 groups.

PRIMARY outcome

Timeframe: 4 weeks after vaccination

Population: Not all participants had this assay done due to the follow reasons: failure to attend the appointment, unwell on the day of follow up, dropped out of the study, assay failure, insufficient blood sample volume or quality.

The IFN-gamma:IL-4 cytokine ratio in plasma samples taken 4 weeks after vaccination measured by multiplex assay using the Bio-Plex 200 Suspension Array system. Ratio compared between the 3 intervention groups with the hypothesis that the MV+DTP group will have a higher ratio than the other 2 groups.

SECONDARY outcome

Timeframe: 4 weeks (9 and 10 months of age)

Population: Study infants at 9 and 10 months of age. Not all participants had this assay done due to the follow reasons: failure to attend the appointment, unwell on the day of follow up, dropped out of the study, assay failure, insufficient blood sample volume or quality.

Plasma pertussis toxoid antibodies were measured by multiplex microsphere-based fluorescent immunoassay at 9 and 10 months of age

SECONDARY outcome

Timeframe: 10 months (19 months of age)

Population: Study children at 19 months of age. Not all participants had this assay done due to the follow reasons: failure to attend the appointment, unwell on the day of follow up, dropped out of the study, assay failure, insufficient blood sample volume or quality.

Measles antibody levels were measured by haemagglutination inhibition assay (HAI) at 19 months of age, 4 weeks after MV challenge at 18 months of age. The aim was to determine whether the vaccination schedule at 9 months of age altered responses to a subsequent MV challenge at 18 months of age i.e., the antibody measurement was made 10 months after the first study intervention.
