Despite availability of free routine immunizations in low- and middle‐income countries, many children are incompletely vaccinated, vaccinated late for age or drop out over the course of the immunization schedule. A major reason for non-adherence to the vaccine schedule is caregivers’ unawareness of trivial but crucial knowledge regarding immunization. Official helplines where caregivers can reach out with queries and concerns are virtually non‐existent and frequently not attended by staff due to competing priorities. As a result, caregivers delay or forego vaccinations, causing coverage to remain low.
In collaboration with software architects from Interactive Health Solutions (IHS), we are developing Bablibot, an innovative AI-powered vaccines chatbot. By instantaneously responding to caregiver queries with accurate information, and addressing common concerns, Bablibot will significantly improve vaccine uptake. Unlike conventional chatbots that respond through rule‐based actions based on keywords, Bablibot will leverage Natural Language Processing (NLP) technology to process and generate responses in unconstrained written language. The conversations will also be validated through human-in-the-loop (HITL) to enhance the AI model . Caregivers will be able to access Bablibot through simple text messaging, which will preclude the need for data connectivity or smartphones, making the intervention suitable for resource-constrained settings. Through our partnership with Expanded Program for Immunization (EPI), we will disseminate information about Bablibot and provide its number to caregivers through selected EPI centers in various areas of Karachi, Sindh.
