Designing a reliable and convenient way to manage children’s immunization records
My Role
UX Designer
Responsibilities
Conduct user research, visual design of low-fi and high-fi wireframes, prototyping, usability testing and iteration.
Relevance of having organized records
Immunization plays a crucial role in preventing the resurgence of diseases, avoiding outbreaks and reducing spending and demand on public health systems. Incomplete dose records, difficulties in tracking vaccination status and inconvenience, complicate the process for families, leaving both parents and healthcare providers struggling to ensure children remain fully protected.
Understanding the challenges first
By exploring the different methods parents use to manage the records and keep track of their children’s immunization, as well as what challenges they face and expectations they have, it was possible to identify opportunities to make the process more convenient, reliable, and accessible.
Paper documents
are unreliable
Doses are often forgotten due to a lack of reminders
Clear information about vaccines and diseases they prevent is relevant
The possibility to share the data and the responsibilities is important
*Those were the key insights learned during the research process
Reaching out to the app’s target audience
Qualitative research was conducted with parents of different demographics with the goal of understanding the methods they use and challenges they face while managing the immunization records.
What was learned
The findings revealed common behavior patterns between parents. Some were more proactive, others relied or shared the responsibility with their trusted healthcare professionals and there were also those who felt overwhelmed. The interviews gave valuable insights about how to help with the challenges faced by them.
PROACTIVE PARENT
Actively monitor vaccination status with partner or by themselves
Get informed before doctor's appointment
Set reminders themselves
DEPENDENT PARENT
Leave the responsibility for follow-up and reminders solely to the doctor or health professionals
OVERWHELMED PARENT
Rely on their partner and pediatrician
Can't keep track of things accurately themselves
Have difficulty understanding the technical terms
*Common behavior patterns could be sorted into 3 different groups of users
Setting the right direction
After reviewing the collected information about the users, setting goals and creating hypothesis, it was time to analyze the competitors, their strengths, weaknesses and figure out opportunities.
*Comparing the competitors’ first impressions
Time to brainstorm ideas
Starting with paper sketches to generate ideas as quickly as possible. First focus was on the main features and first impressions of the app.
Moving on from paper to the screen
Since part of the goal was to create an intuitive app, the information distribution and screen flow are key.
*The app starts to get shape with the help of wireframes
What is the easiest way the users can move through the app?
The clearest path was designed with the user goals and main features in mind. Every main feature should be accessible from the main screen. From there, the secondary actions were disposed in a thoughtful matter not to make the screen too busy. The information architecture was designed considering these principles.
*The information architecture prioritized ease of navigation by using familiar design conventions.
A.I. as a tool
At different stages of the project, A.I. was used not to generate content, but as a tool to sort data and enhance solutions, in order to optimize the workflow.

DESIGN ITERATION
*UI Design iterations with A.I. as a tool.
Working on a design system
The app design incorporates a softer green palette to transmit trust and protection. Additional colors serve as visual cues for alerts or to improve legibility by giving contrast to text and icons. The font choice of sans serif gives a friendly and approachable feel, distancing itself from typical serif font for long and technical text. Building a design system using Figma with components, variables and tokens allowed the design to be easily scalable.
*The pallets, types and icons create the visual identity of the app.
Testing the prototype
Focusing on the three main functions of the app (reminders setting, sharing with others and disease information), the moderated usability study asked participants to perform 3 tasks and evaluated the results and iterated the design based on time on task and drop-off rates vs. conversion rates KPIs.
Presenting the solution
The prototype has the basic structure of an App with onboarding screens, overview and functions connected with built-in and third-party apps from the phone, such as calendar, printer and social media. The app is responsive working on different screen sizes thanks to auto-layout settings.
