RÉSUMÉ
Background: India became the first country in the WHO South-East Asia Region (SEAR) to introduce the rotavirus vaccine (RVV) in the Universal immunization programme (UIP) in 2016 with nationwide expansion by 2019. It was a landmark move to reduce the diarrheal disease burden in under-five children. To assess the implementation process of introduction of RVV, Post Introduction Evaluation (PIE) was conducted in March 2022. Methods: The evaluation was conducted across 14 states, 28 districts and 28 health facilities to obtain a nationwide geographical inclusion. Stakeholders involved in program decision-making, planning, training, vaccine delivery, logistics, and communication from all levels (National, state, district, health facility, health worker, caregiver) were interviewed using standardized data collection tool for PIE (adapted from the standard WHO PIE questionnaire) and scripted on a digital tool. Results: A total of 260 interviews were conducted. Political willingness, well-planned preparedness activities, securing vaccines timely, strong supply chain monitoring, availability of domestic RVV products, quality trainings and intense communication activities were the key factors identified for the successful RVV introduction. Key activities during the introduction included cold chain space assessment, trainings of healthcare workforce, dissemination of job aids, updation of recording & reporting formats and strengthening of AEFI surveillance. Lack of community awareness for immunization in a few areas, fear of AEFI amongst some caregivers and local issues with Alternate Vaccine Delivery (AVD) were some reported challenges in achieving high coverage for RVV. Conclusions: Overall, the nationwide roll-out of RVV was smooth and the vaccine has been well-accepted in the community. The assessment emphasizes on having a well-strategized operational and communication planning, which is very crucial for any new vaccine introduction.
RÉSUMÉ
Background and aims: The Rotavirus vaccine (RVV) introduction is a landmark event in the history of Indian public health as for the first time a novel, low-cost indigenous vaccine was introduced in a short timeline between 2016 and 2019. As per WHO mandate, post-introduction evaluation (PIE) be conducted within 6 to 12 months of vaccine introduction to provide an understanding of the operational aspects of the program. For RVV PIE, an innovative approach to developing and deploying a digitized tool was employed. The present study aims to document the processes followed for digitizing the data collection and analysis tools. Methods: The development of the RVV-PIE digital tool was undertaken in two phases. In the first phase, conceptualization and iteration of the modified WHO PIE tool were undertaken. Questions were organized sequentially to ensure natural progression in responses. The finalized questionnaire was converted to a digital version and extensive dummy data was entered to improve automated qualitative data analysis. Phase 2 involved updating the draft tool and incorporating changes to provide a field-tested version for deployment. Results: The digital version of the tool was successfully developed. The GPS functionality of the tool allowed live tracking of data collection making the process more accountable. The tool was prepopulated with reference materials and data points for easy reference and retrieval by the evaluators. The digitization of the tool also allowed easy visualization of data through maps, charts, and graphs on a real-time user-friendly dashboard. Conclusions: The digitization of the PIE tool for RVV in India has been a great learning experience where the dire situation of an ongoing pandemic catapulted us towards a more efficient and comprehensive process innovation. The RVV PIE tool could serve as a customizable digital PIE tool for other health programs heralding an era of a more effective and proficient process of PIE.
