Background and study aims
We conducted a pilot study of participatory learning and community engagement interventions to improve vaccination coverage in children under 24 months of age in rural Uttar Pradesh, India. The study was designed to assess feasibility and improve methods for a future study of these interventions.
Who can participate?
Women living in 12 villages in rural Uttar Pradesh who were mothers of a child 0 to 23 months of age.
What does the study involve?
Villages were randomly allocated to either the intervention group or the control group. Over 4 months, the intervention group villages received home visits by volunteers and community mobilization events to promote immunization. The control group villages received community mobilization to promote nutrition. A toll-free number for immunization was offered to residents in both groups.
What are the possible benefits and risks of participating?
Possible benefits include increased knowledge about child health (immunization and nutrition). We anticipated no specific risks to participation in the study.
Where is the study run from?
Pratham Education Foundation - ASER Centre (India).
When is the study starting and how long is it expected to run for?
January 2014 to June 2014.
Who is funding the study?
The Bill & Melinda Gates Foundation, the Canadian Institutes for Health Research and the Shastri Indo-Canadian Institute.

| Scientific title | Participatory learning and community mobilization interventions versus usual care to increase immunization coverage among children 12-23 months of age in India: pilot study for a cluster randomized trial |
| Study objectives | We hypothesized that delivery of participatory learning and community mobilization interventions to increase immunization coverage among children 12-23 months of age in India would be feasible. |
| Ethics approval(s) | 1. Pratham Ethics Committee, B 4/54, Safdarjang Enclave, New Delhi, India, 10/12/2013 2. Research Ethics Committee of the University of Montreal Hospital Research Centre (CRCHUM), CE 12.391, 10/04/2013; updated 10/12/2013 |
| Health condition(s) or problem(s) studied | Vaccine-preventable diseases in children (tuberculosis, polio, diphtheria, pertussis, tetanus, Hepatitis B, measles) |
| Intervention | Clusters were assigned to the intervention group (IG) or the control group (CG) using a computer-generated randomization schedule. Neither participants nor those delivering interventions were blinded, but those assessing outcomes were blinded to group assignment. Over 4 months, IG villages received: 1. Home visits by volunteers 2. Community mobilization events to promote immunization CG villages received community mobilization to promote nutrition. A toll-free number for immunization was offered to all IG and CG village residents. |
| Intervention type | Behavioural |
| Primary outcome measure | Primary outcomes were ex-ante criteria for feasibility of the main study related to processes for recruitment and randomization (50% of villages would agree to participate and accept randomization; 30 women could be recruited in 70% of villages) and retention of participants (50% of women retained from baseline to end line). |
| Secondary outcome measures | We studied process indicators related to implementation fidelity and two indicators of community response. We also studied three proxy indicators of intervention impact on immunization uptake. We described differences between IG and CG villages for two cluster-level outcomes: 1. Use of the toll-free number 2. Monthly immunization day footfall 3. We compared performance of IG versus CG participants on the change from baseline to end line survey on key knowledge and awareness indicators. |
