Thank you for initiating this important discussion.
The inclusion of TPVS active vaccine carriers in CCEOP is a positive development, particularly for immunization programs operating in challenging environments where maintaining temperature throughout transport remains a significant concern.
From my perspective, these devices could help address gaps in last-mile vaccine delivery, outreach sessions, and prolonged transport to remote or hard-to-reach communities where passive cold boxes may not always provide sufficient temperature assurance. Their ability to actively maintain the required temperature range has the potential to reduce vaccine wastage and improve confidence in vaccine potency.
That said, successful adoption will depend on more than the technology itself. Considerations such as total cost of ownership, maintenance requirements, battery performance and charging infrastructure, availability of spare parts, local technical support, and user training will be critical to long-term sustainability. Programs will also need clear guidance on selecting appropriate use cases where the added value of TPVS carriers justifies the investment.
The inclusion under CCEOP could significantly improve access by enabling countries to evaluate and procure these devices through established funding mechanisms. However, implementation should be accompanied by operational guidance, performance monitoring, and documentation of country experiences to build the evidence base for broader adoption.
Overall, I see TPVS active carriers as a valuable addition to the cold chain toolkit—not a replacement for existing passive equipment, but a complementary solution for specific operational scenarios where they offer clear advantages.
