Problem Statement
- There are no proper records of the vaccinations given by the public health clinics. How do we maintain the records?
- How do we provide a persistent storage on the cloud as well as physical?
- Can we aid in the identification of patient-How?
We are currently piloting in two villages- Trapaj and Narmada, Gujarat, India.
We first began by making a chart of all our stakeholders in this space of rural healthcare in India. You can see a complete list of all our stakeholders below.

SWOT
|
Strengths
| Persistent Storage Lockets are attractive creates awareness |
Weaknesses
| lack of current vaccination awareness. | |
Opportunity
| vaccine camps | |
Threats
| PHC's don't find idea worth. | |
LEARNING AND INSIGHTS
Mothers are pretty aware of vaccinations.
|
Information of next camp and vaccines to be given specifically to their kid was missing.
|
Doctors are willing to incorporate new technologies.
|
Smartphones are used extensively.
|
English is not that common.
|
PROPOSED SOLUTION AND INITIAL DESIGN
Locket Based Data Storage with an AWS storage and notification service on an Android Phone
|
S3 Storage, SNS Service-AWS
Android App for PHC worker to enter data. locket- given to mother. |
Why would a mother wear a locket?
Give it in form of a religious locket( a Ganesha/ a Holy Cross/ a taveez), and you prevent loss of the locket at any costs!!
This app is to help people in impoverished areas on India by providing them a solution to their vaccination records which may be lost over time. This application will help parents record which vaccinations have already been administered to their children, and which are to be still administered, as well as if they can be administered on that day or not.
EXPERT INTERVIEW-1
Dr. Rohitbhai Modi
Paediatrician,
Lord Krishna Hospital
12 August’18
|
Q. What do you feel about the vaccination scenario in India
Ans. It is improving, but a lot of misinformation is present. People should take more interest and get more awareness.
Q. Do you feel parents are unaware of vaccinations that are needed for their children?
Ans. Yes, the latest experience of MMR in our state has highlighted the impact of fake news/ misinformation. The government should take steps to clear such queries.
Q. What are the problems you feel need to be resolved?
Ans. Misinformation among the people.
Which vaccines to be taken when.
Q. Do you feel a device that enables the doctors will help them?
Ans. Yes, if people get to be more aware.
Will data be protected?
Q. Would parents get aware using the text system?
Ans. Yes, but need to be updated beforehand.
We could try with one of my patients.
EXPERT INTERVIEW-2
Kantaben Parmar
Asha Worker,
Sarkhej Constituency.
15 August’18
|  |
Q. Tell us about the hardships you face for proper vaccination.
Ans. Vaccinations need to be given at the right times. I tirelessly go on the community by community talking to mothers to bring their children to the camps.
Q. Are records really helpful for vaccines?
Ans. They are not regarded with the importance they should be given.
Q. Will such a device help?
Ans. I do not think so, a lot of my colleagues do not know English properly.
Q. What if there are more symbols?
Ans. Might work. Why not something in Gujarati?
Q. Which phone do you use?
Ans. Samsung J7 Max.
Q. Will you like to work on the interface?
Ans. Yes, it is worth a try.
EXPERT INTERVIEW-3
Anisha ben,
Mother of Raghav
19 August’18
|  |
Q. When was the last time Raghav got a vaccine?
Ans. Two-three months ago.
Q. Where did you go?
Ans. Near the zoo.
Q. Who told you that a camp was there?
Ans. A lady I work for.
Q. Which phone do you use?
Ans. Nokia, some model.
Q. Would you wear a locket of this sort?
Ans. Yes, it looks beautiful. But why?
Q. Can you read English?
Ans. No.

Hardware
NFC System (Near Field Communications):
The NFC system consists of two main components, a transponder or a
tag which is located on the object that we want to be identified, and a
transceiver or a reader. The NFC reader consists of a radio frequency
electromagnetic field. On the other hand, the tag is usually a
module, a control unit and an antenna coil which generates high
microchip, so when it gets near the electromagnetic field of the passive component, which consist of just an antenna and an electronic
and this voltage serves as power for the microchip.
transceiver, due to induction, a voltage is generated in its antenna coil
Now as the tag is powered it can extract the transmitted message from the reader, and for sending a message back to the reader, it uses a technique called load manipulation. Switching on and off a load at the antenna of the tag will affect the power consumption of the reader’s antenna which can be measured as voltage drop. This changes in the voltage will be captured as ones and zeros and that’s the way the data is transferred from the tag to the reader.
The Vaccinator’s Tag:
These tags have 1kb of memory and have a microchip that can do arithmetic operations. Their operating frequency is 13.56 MHz and the operating distance is up to 10 cm depending on the geometry of the antenna. If we bring one of these tags in front of a light source we can notice the antenna and the microchip that we previously talked about.
The Vaccinator’s Module:
The NFC Reader Module uses the SPI protocol for communication with the Arduino board.
Working:
After the doctor registers itself on the application, the vaccine that has to be given to the child gets written in the form of a string having 351 bytes. These 351 bytes gets stored in the Vaccinator’s Tag in different blocks of the memory architecture. This particular string stored in the Vaccinator’s Tag can be read by any doctor given access to the application.
