Provide a one-line summary of your solution.

ChanjoBox, a portable solar fridge that can be mounted on a motorbike, bicycle, or boat, to safely store and transport vaccines, drugs, and blood for transfusion to remote, hard to reach and off-grid rural communities.

What specific problem are you solving?

Globally, 3 billion people are at the risk of contracting a Vaccine Preventable Disease because their healthcare facility does not have a cold chain to store vaccines. Our solution is bridging a gap in the rural healthcare sector by ensuring that heat-sensitive items, such as vaccines, blood for transfusion, and drugs like insulin, have the appropriate cold storage to ensure every single person has access to equitable healthcare.

ChanjoBox is lengthening the shelf life of heat-sensitive medical items so everyone can access these essential medications and medical services irrespective of where they live. ChanjoBox is also broadening the geographical reach of these healthcare items. Our solution ensures these medical items are also available to people who cannot access healthcare facilities. For us, we must integrate portability into trying to solve the issue of inaccessibility of medical items.

What is your solution?

ChanjoBox, a portable solar fridge that can be mounted on a motorbike, bicycle, or boat, to safely store and transport vaccines, drugs, and blood for transfusion to remote, hard to reach and off-grid rural communities. The solution is also IoT-enabled; integrated with a communication and digital component that collects data in real-time and stores it on a cloud. This ensures that vaccines are kept in the best storage conditions and can also be traced, to promote effective healthcare programs in rural communities.

Our solution is also solar-powered, which is important because the target communities that benefit from ChanjoBox are in off-grid places with intermittent power. Solar is also a more affordable option. ChanjoBox also has a built-in battery backup because we must ensure that the fridge remains in operation at night.

The most exciting thing for us about ChanjoBox is the Internet of Things (IoT) solution. We had to integrate it with a smart data management application. Wherever the fridge goes, it can record the temperature in real time and transmit it back to us. We need to have the ability to track this data because, in local health care facilities in Kenya, they still record data in books, then it’s taken to a governmental agency known as the District Public Health Nurse (DPHN) at the end of the month. If a fridge had a temperature excursion at the beginning of the month, the DPHN will only be aware of this at the end of the month, and it is too late to take action.

We try to ensure that the ChanjoBox is monitored at all times, so the data is up-to-date, and data-driven solutions are in action to ensure that no vaccines go bad. If the temperature exceeds what is expected, ChanjoBox sounds an alarm, and that temperature is recorded. If it’s too low, that is also recorded, so we know to adjust appropriately and ensure that the vaccines remain in appropriate cold storage as much as possible. The IoT solution for the fridge eventually morphed into an AI-enabled solution that we want to integrate into ChanjoBox because we ultimately want to distribute the fridges into far-off places.

How many people does your solution currently serve?


Why are you applying to the Prize?

For us, it is honestly life-changing. We want to grow our business and we find that most of our roadblocks are financial. A challenge with the current state of manufacturing for the fridges is that we are outsourcing a lot of production, making it more expensive. When we started this project, we wanted to provide not only an effective solution but also an affordable one. So one of the first things we want to do is set up our own manufacturing facility so we can produce these fridges in-house. And that will drastically reduce the cost of ChanjoBox and make them more accessible. This prize will give us a unique opportunity to break into the domestic market. We’ve seen considerable demand, and customers have approached us from other countries across Africa, including Malawi, Mozambique, and Zimbabwe. Having the funds to produce this at scale will help us match the growing demand for the solution and create as much impact as possible.

 I’m glad we can hire more team members to help us do this work because it’s been our dream, and we’ve done so much work in the past few years. When we started this work, there was skepticism about manufacturing these fridges in Kenya. Just being recognized and awarded by MIT Solve is a confidence boost for us. It’s always hard on entrepreneurs trying to bring innovation into the world. With the stamp of approval from MIT Solve .

We want to increase our production capacity, acquire more tools for our manufacturing facility, and get our own facility. The money from THE HORIZON PRIZE: 2023 will give us so much runway to sustain that manufacturing facility and complete our work and make enough fridges for the growing list of potential customers. We also want to grow our IoT solution this year; it’s still a work in progress. Many challenges that we’re facing are expensive challenges. Some of our goals are to get the right people and the right equipment and to ensure that the IoT solution is always online and working.

Who is the Team Lead for your solution?

Elisha Caleb

How is your Team Lead connected to the community or communities in which your project is based?

As a Young Dad who moved from Nairobi to a rural community, I have faced the challenges of trying to have my child vaccinated. When I lived in Nairobi, I never thought twice about access to vaccines or certain medications because they were available. You become oblivious to the challenges in communities that do not have access. I moved to a rural community right after my daughter was born, and that was when the challenge became real. Vaccines are not always available. There are specific times and days for vaccinations; if you miss that day, it’s a missed opportunity. And I saw mothers who gave up because they walked a long distance to get vaccinated. Or sometimes, they don’t have the finances to travel back to the facility.

Given all the circumstances, it was apparent that we needed to design a fridge for medical use in rural communities in Africa. Health care workers carry vaccines in an ice box on their motorbikes or bicycles and take them to facilities. But the cold box is not a refrigerator, and sometimes the temperature can fall outside the desired range and there is no way of monitoring this, so it’s not safe. So, we had to design a portable solution available for different modes of transportation and keep items in storage while in motion. We also had to ensure that all children and adults get a chance to get a vaccine.

More About Your Solution

What makes your solution innovative and sustainable?

ChanjoBox, a portable solar fridge that can be mounted on a motorbike, bicycle, or boat, to safely store and transport vaccines, drugs, and blood for transfusion to remote, hard to reach and off-grid rural communities. The solution is also IoT-enabled; integrated with a communication and digital component that collects data in real-time and stores it on a cloud. This ensures that vaccines are kept in the best storage conditions and can also be traced, to promote effective healthcare programs in rural communities

We are a young team, and being open to new ideas has helped us develop the solution. Initially, we started thinking about portable fridges for dairy farmers. Then COVID happened, and we pivoted because we saw a need for a solution like this in healthcare. We initially imported a generic fridge and took it to the field to get feedback from healthcare workers.

What has been innovative about our approach is that the development of ChanjoBox is guided by feedback we’ve gotten from healthcare workers. We decided to add the IoT feature because we heard from the healthcare workers that it was challenging to manage and ensure the accuracy of the data they were writing in books. Working directly with healthcare workers is very important because they are the users of this solution and have experience in the field, so they know what type of solution works best for them.

How we want to provide full after-sales support sets our solution apart. As the manufacturer, we are responsible for ensuring that these fridges remain operational all year and over the next three years. So, it’s good for us to have sufficient data for predictive maintenance. For example, if we try to see that fridge X is at a particular facility and seems to be heating up quickly, maybe the insulation is wearing out. We need to start planning how to repair our fridges to avoid discarding them for problems we can fix. It becomes a menace to the environment when fridges go into a landfill and become e-waste. It’s also a waste of money because cold storage is so expensive. So, if you can do predictive maintenance, it will be cheaper for the end user.

ChanjoBox: The  solar-powered vaccine box is a solution  used to transport and store vaccines in areas with limited or unreliable access to electricity. It is equipped with solar panels that capture sunlight and convert it into electricity, which is then used to power the box and keep the vaccines at the required temperature.

Here's how it works and why it makes a difference:

  1. Reliable power source: In many remote areas or developing countries, electricity supply can be inconsistent or unavailable altogether. This can be a problem because vaccines need to be stored at specific temperatures to remain effective. My solution: ChanjoBox solves this issue by providing a reliable and sustainable source of power. The solar panels on the box collect energy from the sun during the day and store it in batteries, which can then be used to power the box even when there is no sunlight.

  2. Temperature control: Vaccines are sensitive to temperature variations. If they are not stored within a specific temperature range, their effectiveness can be compromised, and they may even become unusable. ChanjoBox is designed with insulation and cooling mechanisms to maintain the required temperature. The solar power ensures that the cooling system continues to function, even in areas without electricity, keeping the vaccines safe and effective.

  3. Expanded reach: By providing a reliable means of storing vaccines in areas without electricity, ChanjoBox expands the reach of vaccination programs. It enables healthcare workers to transport vaccines to remote locations, including rural areas or regions with limited infrastructure. This is particularly crucial for reaching vulnerable populations who may not have easy access to healthcare facilities. By ensuring the availability of vaccines in these areas, more people can be protected from preventable diseases.

  4. Reduced wastage: Without proper temperature control, vaccines can spoil and become unusable. This wastage not only leads to financial losses but also means that people are deprived of vital immunization. CanjoBox helps minimize vaccine wastage by maintaining the necessary temperature throughout transportation and storage. This ensures that vaccines remain effective and can be administered to those who need them.

In summary, the solar-powered vaccine box addresses the challenges of reliable power supply and temperature control, enabling vaccines to reach remote areas and vulnerable populations. By reducing wastage and expanding the reach of vaccination programs, it plays a crucial role in increasing immunization coverage and protecting more people from preventable diseases.
