Taqnia Africa aims to empower community health workers through a web based platform that enables them manage immunization records, provide a portable smart solar vaccine cooler container which will make sure the vaccines are delivered in good condition and a system that sends automated messages to the caregivers on upcoming immunizations.

Explain the innovation (2,500 characters)

According to National Center for Biotechnology Information , community health worker(CHW) interventions are key to optimal infant immunization coverage . Also according to Gavi in their urban immunization toolkit, informal settlements continue to develop with the growth of cities. It is always a challenge to access quality health services in these informal settlements like immunization. With our platform CHW will be able to register new infants or migrants into the system that have children within immunization age in the community, capture the immunization history through a questionnaire that will be filled in the system, child’s data, automatically capture their gps coordinates, capture the facial and fingerprint bio-metric data of the caregiver and the time they would likely be available to get their children vaccinated. This information will be saved on the CHW's device and later transmitted to the online database where it will be analyzed, processed and stored to be relayed to relevant health services providers and researchers depending on their level of clearance to access the data. The system will also contain important materials like immunization educative videos, online schedules to be used by CHW during training and community outreach. During immunization the CHW will capture the child’s information, vaccine given, caregiver information, including facial and fingerprint image for bio-metric recognition. The data submitted will be saved locally on the devices provided and transmitted automatically to and online database which will process the data and save it. The system will notify the community health workers on where and when to collect the vaccines and notify the caregivers on the upcoming immunization. We will also provide the community health worker with a smart solar cooled vaccine container that is 3D printed. This container will keep the vaccines cool during field immunization. The container is also fitted with a gps tracker, thermal monitor and a fingerprint lock . The container will be sending geo-location and vaccine temperature data to our systems and when the container is unlocked it will always alert us who has unlocked it and where and when this was done. This solves the problem of poor immunization records and monitoring and relays information to caregivers and CHW on important immunization period.

Which part(s) of the world does this innovation target?

  • North Africa
  • Eastern Africa
  • Middle Africa
  • Southern Africa
  • Western Africa
  • Southern Asia

Geographic Focus

The trial phase will be done in the slums of Nairobi, Nakuru and Mombasa.

Stage of Innovation

  • Prototype

Who will work alongside your organization in the project idea? (1,000 characters)

We plan to work with community health workers and county governments under which this slums are based.

How is your idea unique? (750 characters)

Our System is a Progressive Web Application meaning that it is cross platform and it capitalizes on use of bio-metrics data and machine learning to process data. The system will not only be for community health workers but it will also have a restricted API that will be used by other Hospital Management systems to link to our system. The system will always be automatically sending notification and reminders to caregivers and community health workers. The vaccine containers are small easy to carry and solar powered and more so they have bio-metrics and gps security. This will enable some vaccines that really need to be kept in low temperatures to be delivered to people during field work in the best conditions .

Hi Timothy Maina 
Great to have your idea on the platform, and to understand your approach on accelerating immunization coverage in Nairobi. It will be amazing if you are able to add some visuals/images to your idea, as it helps in making it easier for the community to understand.

Does your idea relate in any way to Chanjoplus  by Collince Osewe Oluoch  ?

Are there any deliberate steps you have undertaken so far with regards to your idea? Are you planning on doing some pilots/tests? How does that look like?

You could check out our prototyping toolkit: , user research toolkit: and our storytelling toolkit:

Hi Isaac Jumba 
Hope you doing well sorry for the late reply , We have made necessary changes of the idea and we hope right now it is more clear, hope to get your view and guidance .
We currently finishing on the development. What is discussed above is just but a module we have added to our system to address the immunization problem. We currently working on partnering with a few hospitals to test our systems before rolling it out to government hospitals and other hospitals. We currently have two local hospitals that have agreed to work with us. We are hoping by the end of June to have completed the testing phase and the new community health worker module.
Thank you in advance hoping to hear from you.

Thanks Timothy Maina  for the reply. Great to know that you have already done small pilots of your idea and are looking to roll out in government hospitals soon. Could you share some results and insights from the pilot so far?

How many people are you hoping to reach out with your solution and within which time frame? Lastly, it will be interesting to share around your business model

You welcome Isaac Jumba  and forgive me for late reply. What we noted from our pilot is that for the hospital they actually never used the triage module. They even requested that we make it optional . 3 modules were well appreciated which were the registry module, clinical module and the pharmacy module.
From the patients that we had a chance to interact with they requested to have their own application and for the system to include a referral module. For the patients application there were few things that we noted we could work on as we build it.
1. We could make it possible for the patients to do advance booking, so as to save on time used at the queue.
2. For the cases where the hospital lacked some of the prescribed drugs we could add chemists into the system where the patients could see at how much the drugs were being offered, after which they could purchase their drugs from the app.
3. Another request was to make it possible for the patients on their app to view hospitals near them, with the kind of services and cost being offered in those hospitals.

With the help of community health workers especially in Kibera, we are estimating to reach 100,000 people within the first year of which the numbers could be more.
