Abstract 

Effective vaccine delivery is critical for the control of many human, animal and zoonotic pathogens. Despite awareness of the need for cold-chain preservation, vaccine delivery falls short in many isolated regions of the world because of inadequate refrigeration. Specifically, the vaccine cold-chain is often broken at the last miles of the delivery. Current vaccine carriers claim 10 hours of cooling whereas last-mile journeys can take up to 7 days. Vaccines are spoiled during transportation and during immunisation sessions. Two vaccine carriers used for last-mile journeys in Nigeria are tested in laboratory. The experiments are conducted with controlled factors based on real-life vaccine delivery data. The results show the performance of vaccine carriers that have remained closed versus those that have been repeatedly opened and closed to simulate field immunisation sessions. Recommendations on improving the last-mile cold-chain are provided. A novel vaccine carrier is designed to solve current problems and reduce vaccine wastage throughout the last-mile vaccine delivery.
