In the realm of preventive healthcare, the promotion and accessibility of vaccines play a pivotal role in achieving large-scale public health outcomes. A comprehensive digital outreach initiative, conducted from FY2021 to April 2024, offers a compelling case study on how data-driven omnichannel strategies can significantly enhance engagement with healthcare professionals (HCPs) and facilitate better vaccine distribution.
This initiative aimed to build awareness, recall, and accessibility around multiple vaccine products by targeting key specialties such as Pediatrics, General Practice, and Pulmonology. The program utilized a healthcare engagement platform to deliver focused interactions, supported by digital infrastructure to ensure smooth delivery of educational content and transactional facilitation.
Methodology and Execution
The campaign deployed a multichannel digital strategy:
- Web-based and app-based touchpoints
- Email, SMS, and WhatsApp for updates and reminders
- Tele-calling for follow-ups, order assistance, and feedback
- Microsite with a knowledge hub and integrated ordering system
- Monthly re-engagement of previously active HCPs
