Summary

Problem

Although COVID-19 vaccines are widely available in the United States, low COVID-19 vaccination rates and high vaccine hesitancy remain prevalent amongst Atlanta-area college-age young adults. These circumstances present an opportunity to engage in the process of research and design to best understand and provide for the immediate assets and needs of local COVID-19 vaccine-hesitant university students.

Solution

VaxU is a mobile-based healthcare provider portal that attempts to address the COVID-19 vaccine hesitancy of Atlanta-area college students. It seeks to accomplish this by giving the ability to conveniently book COVID-19 vaccine appointments, providing channels of direct communication with university healthcare providers for their COVID-19 vaccine concerns, and offering up-to-date supporting information about the COVID-19 vaccines.

By August of 2021, the United States made substantial progress to counter the infectious spread of COVID-19, most notably through the development of three novel vaccines that proved to reduce the chance of severe illness, hospitalization, and death from the virus. Despite these vital advancements, COVID-19 vaccination rates stagnated in growth and vaccine hesitancy continued to persist, especially amongst college-age young adults (18-30 years old). In particular, throughout Atlanta-area universities, there was a concerning range of COVID-19 vaccination rates and lingering vaccine hesitancy amongst the local student populations. As members of this community, we were passionate about using the opportunity of this project to gain an insightful understanding of this problem space to protect the health and wellbeing of those around us.

How might we address the COVID-19 vaccine hesitancy amongst Atlanta-area university students?

Concepts

Concept 1: Healthcare Provider Portal

This portal provides university students the ability to seamlessly complete the process of COVID-19 vaccination at their campus-affiliated health clinics. In addition, this portal facilitates direct communication about COVID-19 vaccinations between students and healthcare providers for both immediate and longer-term concerns.

Concept 2: Scientific Research Database

This database functions as a platform for leading university research scientists to directly translate their latest findings related to COVID-19 and the corresponding vaccines so that students can easily access and understand relevant findings. This database also relies upon multimedia, data visualizations, and readability assessments to ensure that the information is accessible.

Concept 3: Crowdsourced Experiences Platform

This platform utilizes crowdsourced contributions from people who have had experiences with COVID-19 and the corresponding vaccinations to build meaningful connections based on commonalities. This platform relies on an editorial team to vet the crowdsourced submissions to verify the accuracy of their contents.

Concept Feedback

After developing our concepts, our team conducted feedback sessions with representative users of our target population of vaccine-hesitant college students. During these sessions, we sought to understand what value each concept offered our potential users. The insight obtained from these sessions demonstrated that our concept of the healthcare provider portal would be most likely to improve vaccine acceptance amongst college students who are hesitant about COVID-19 vaccination.

User Flow

To develop our concept of the healthcare provider portal, our team established a user flow that encompassed the primary interactions and information found within the platform.
