Formative study on Vaccine Indicator and Reminder (VIR) band to improve vaccination timeliness and completion in Nigeria

The Health Strategy & Delivery Foundation (HSDF), in collaboration with researchers from Direct Consulting and Logistics (DCL), Johns Hopkins University International Vaccine Access Center (JHU/IVAC) and Precision Development Research and Advocacy (Pakistan) are implementing a research project in Kebbi State, Nigeria. The project seeks to assess the feasibility and acceptability of implementing an innovative vaccine indicator and reminder (VIR) band to improve immunization timeliness and completion among infants in Nigeria.

The vaccine indicator and reminder (VIR) band is a silicon band that serves as a constant reminder to parents/caregivers on the need to vaccinate their children in a timely manner. It consists of a sealed dye blister and a time indicator that is activated at each vaccine (BCG, Penta 1 and Penta 2) initiation. Once a vaccine is administered, the band is activated by pressing the blister, which releases the dye to move along a membrane by capillary action to reach the end point. The ink progression gives a visual clue and serves as a reminder to parents/caregivers to vaccinate children in a timely and complete manner.

The device has been tested among 346 infants visiting vaccination centres in Pakistan, and preliminary results indicate overwhelming parental support of the VIR band concept and compliance with the device.

The project in Nigeria is being managed by Dr Chizoba Wonodi (Lead Principal Investigator), Dr. Noor Sabah Rakshani (Co-Lead Investigator), Dr Sachi Ozawa and Dr Chike Nwangwu (Co-Investigators), Chisom Obi-Jeff (Research Coordinator & Associate); and Jamila Bello Malabu and Ebube Nwaononiwu (Associates).
