An interventional study of SMS reminder and Unconditional Incentive in Measles, sponsored by Johns Hopkins Bloomberg School of Public Health. Completed. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2018-03-01.
Sponsored by Johns Hopkins Bloomberg School of Public Health · Not applicable, Interventional, and Health services research
The overall objective is to test the impact of short message service (SMS) reminders, with or without unconditionally provided mobile-money incentives, can improve measles vaccination coverage in rural western Kenyan infants.
Primary Objective The primary objective is to determine if text message reminders, with or without unconditionally provided incentives, can increase the proportion of children who receive measles vaccination by 15% at age ten months as compared to control arm children.
Secondary Objectives
122 studies on the registry are indexed under Measles; 17 are open to participants now.
This study's planned enrollment of 537 is close to the median of 540 across 95 interventional studies indexed under Measles.

Exclusion Criteria:
All enrolled caregivers will receive a congratulatory text message at enrollment which indicates who is conducting the study and which also includes a general-health related saying, "The greatest wealth is health". No additional text messages or travel subsidies will be sent to caregivers randomized to the control arm.
At enrollment, participants will be told to expect 2 SMS reminders for measles vaccine; first, at 3 days before and second, on the day before the scheduled measles vaccine at 9 months of age. At most, enrolled caregivers will receive three text messages (two for the measles vaccine and one for welcoming mother to the study). Text messages will be sent in English, Kiswahili or Dholuo language, according to the mother's preference. These reminders will have information about the child's scheduled immunization date.
Behavioral: SMS reminder
Participants will receive SMS reminders as described in the SMS reminder arm. Additionally, participants will be sent a 150 Kenyan Shillings (KES) incentive to the mobile phone number they provided at enrollment. The incentive will be delivered three days before the child turns nine months (i.e. sent on the same day as the first SMS reminder). Caregivers will receive the mobile-money incentive unconditionally. The intent of the incentive is to help offset the costs associated with transportation to the clinic. The transaction costs associated with mobile-money transactions will be borne by the study such that mothers will receive the full 150 KES.
Behavioral: SMS reminder · Behavioral: Unconditional Incentive
Caregivers will receive two text message reminders for their child's measles immunization scheduled for 9 months of age
A mobile-money incentive in the amount of 150 Kenyan Shillings will be transferred to the enrolled caregiver's mobile phone when the child reaches nine months of age
Measles vaccination coverage
Proportion of children receiving measles vaccination by 10 months of age by study arm
Time frame: 10 months
Time to measles vaccination (in days) using Kaplan-Meier Survival Analysis
As a secondary analysis of the primary outcome, time-to-measles immunization curves will be constructed using the Kaplan-Meier method and study arms will be compared using the Cox model. The 25th, 50th, and 75th percentiles for time to immunization and the number of days delayed, in relation to the measles due date, will also be reported for each vaccine and by study arm.
Time frame: 12 months
Proportion of children who receive measles vaccination stratified by demographic variables
A priori we will conduct sub group analyses of the primary outcome for mobile phone ownership, birth order of the enrolled caregiver's child, and time to clinic. Additional variables for subgroup analyses will come from a risk factor analysis of not receiving measles vaccination in the control arm
Time frame: 10 months
Measles vaccination coverage at 12 months
Proportion of children who receive measles vaccination by twelve months of age by study arm
Time frame: 12 months
Vaccination coverage for second dose of measles vaccine at 24 months.
This outcome is dependent on receiving more funding
Time frame: 24 months
