SMILE mobile smart last-mile vaccine carrier for vaccination campaigns and disaster relief
SMILE keep vaccines between 2 to 8oC without power during transport and help healthworkers immunise effectively and efficiently.
Describe what you intend to do and how you'll do it in one to two sentences (required 350 Characters)
SMILE’s novel design minimises vaccine spoilage due to temperature fluctuations and human errors during transport and immunisation campaigns. It extends outreach capabilities to 5 days without power in urban and remote areas. We will conduct field trials in June this year and would like to work with countries in urgent need as identified by GAVI.
Explain the innovation (2,500 characters)
Up to 85% of the vaccines are spoiled due to freezing and overheating. Currently, 19.9 million children still lack basic vaccination. Frequently, outreach sessions can take up to 7 days but current solutions last for less than 2 days without opening them.
In addition to the inadequate vaccine carriers available, we observed human errors made by trained health workers during our field visit in remote Nigeria. We simulated these behaviours using existing field vaccine carriers in lab environments and results showed that these errors cause the temperatures to rise above the acceptable limit in a short time. For example, using an insufficient number of icepacks meant the vaccine temperatures were not maintained and the vaccines heated up rapidly. Moreover, leaving the carrier lid open throughout the session and placing usable vials on the floor all put vaccine potency at risk. The manufacturer's device's cold life is in fact shortened dramatically during immunisation when the lid is opened repeatedly.
We focus on solving the thermal problems and create a system that is fail-safe during transport and immunisation sessions. Our smart, low tech device also considers technology and user adaptability for under-privileged and low-resource settings. SMILE keeps vaccine at the required temperatures for 4 to 5 days with a bespoke SMILE icepack. It has a self-closing door and a smart mechanism to separate the cold vaccine chamber from the hot environment when the door is opened. SMILE is designed to be intuitive to cut down training costs. SMILE can be transported on foot, bikes, donkeys, boats and drones easily with a dedicated backpack. SMILE does not need to be removed from the backpack during operation. We are developing a integrated temperature monitoring function and tracking function to provide data for analysis. We have tested the SMILE thermal performance in laboratories and we will be comparing the data with our upcoming field test results. The smart, low tech and user-friendly SMILE will change how vaccines are stored and administered during routine immunisation and in disaster outbreak sessions in both urban and remote settings. In urban areas, SMILE can be prepared in a mobile clinic and will either be stationed at the clinic or be transported by healthworkers to a designated area for immunisation. The location and the performance of the carrier will be registered by the electronics within the device.
Which part(s) of the world does this innovation target?
The innovation would suit areas with a hot climate, terrain where it is difficult to deliver vaccines and slum areas which may be limited in space and prone to outbreaks of diseases. This would be suitable for most countries in Africa, South and Southeast Asia, and Central and South America.
Who will work alongside your organization in the project idea? (1,000 characters)
We have been working with field experts from industries, universities and NGOs who provide product feedback. However, we would like to work closely with GAVI, the WHO and more stakeholders to ensure we bring their valuable feedback board for greater impact. We have a few novel elements in the device and a bespoke temperature monitoring part integrated within the device, we would like to collaborate with the WHO for any additional requirements that were not covered in the passive freeze-free standard. This may result in a new version of the passive standard being drafted or a new category that our device and any future innovations could apply to. We feel that frequent catch-up meetings and open-minded discussions with our collaborators help make the best progress. We have established long-term relationship with many field researchers, the Royal Academy of Engineering, the Expo Live team and the Centre for Global Equality. We would be grateful to work with those sharing the same vision.
How is your idea unique? (750 characters)
Our team has in total over 40 years of experience in designing temperature systems, mechanical engineering, manufacturing, medicine and user-centred design for low-resource settings. The performance of a well-designed device would be compromised if used incorrectly. SMILE has gone through stages of iterations. SMILE is unique and has a self-closing door which addresses one of the most common human errors observed in the field. This substantially reduces heat transfer in extreme weather. Our innovative mechanisms allow users to take out and put in the vaccine vials without compromising the coolness in the storage compartment. Our technologies can be implemented in existing vaccine carriers to extend their cold life.
