Why do people refuse protection that already exists?

The Dandelion Project studies how trust, perception, and access shape real-world health decisions.

Prevention does not fail only because it is absent. It fails because it is not chosen.

About the Project

The Dandelion Project began with a question, not a campaign.

Chuxuan (Kaylee) Zhang, 17, attends Queenwood School for Girls in Sydney. Born in China and raised between Beijing and Sydney, she developed the Dandelion Project to study why preventive health knowledge does or does not become action.

The gap: influenza vaccination rates in China sit below 4%, while the United States reaches 42–47%. Same virus, same science — fundamentally different decisions.

In July 2025, Kaylee brought that question to Zhangcao Village, Shanxi.

That experience led to the Dandelion Decision Framework: Trust, Perception, and Access.

Core Insight
Access does not equal action.
Conceptual Framework

The Dandelion Decision Framework

A behavioral model for understanding why prevention is available, but not always chosen.

Framework
Trust
Who people believe
Perception
How people interpret risk
Access
Whether action is practical
Chosen Prevention
Trust
Who people believe

Trust shapes whether health information is accepted, ignored, or questioned.

Health information is filtered through relationships before it becomes belief.
Perception
How people interpret risk

Preventive action depends not on objective risk, but perceived risk.

Behavior follows perceived reality more often than medical reality.
Access
Whether action is practical

Even when trust and perception align, action fails if access is difficult.

When action is inconvenient, delay often becomes refusal.
The Interaction

Why these forces must be read together

Preventive behavior becomes possible only when trust, perception, and access all align.

“Prevention is chosen when belief, urgency, and practicality align.”

Beijing Activity Results · Fugezhuang Village · June 28, 2026

A field-tested education workflow

The Beijing session translated the Dandelion framework into a complete field workflow.

Valid questionnaires

Matched pre/post responses were compiled from the Beijing activity.

28.8% → 100%
Vaccine understanding

The vaccine-risk item increased from 23/80 before the session to 80/80 after.

100%
Post-session satisfaction

All valid post-session responses selected the positive option.

Field Notes · Zhangcao Village · July 2025

What we observed

Community session
Kaylee presenting
Audience
Landscape
Community
Observation 01

Understanding does not guarantee action

Many parents showed clear understanding of influenza transmission and vaccine benefits. However, hesitation remained when actual vaccination was discussed.

Insight

Knowledge alone is not sufficient to drive preventive behavior.

Observation 02

Trust is relational, not institutional

Parents were strongly influenced by local doctors, family members, and community figures — not generalized health messaging from distant authorities.

Insight

Trust is built through relationships, not information delivery alone.

Observation 03

Passive systems lead to inaction

Without stronger coordination from schools, clinics, or community structures, many families delayed or avoided decision-making altogether.

Insight

When action requires individual effort at every step, inaction becomes the default.

Observation 04

Risk perception is uneven and personal

Some parents underestimated influenza severity; others feared vaccine side effects more than the disease itself.

Insight

Perceived risk, not objective risk, often drives behavior.

Observation 05

Small barriers have disproportionate effects

Even when parents seemed open to vaccination, small constraints — time, logistics, uncertainty — often disrupted follow-through.

Insight

Behavioral friction, even when minor, can substantially reduce uptake.

What These Observations Changed

These field observations challenged the assumption that awareness alone drives action.

If knowledge is not enough, what actually changes behavior?
Project Timeline

Leadership

Design, research, fieldwork, and scale

Kaylee Zhang

Independently initiated and led by Kaylee Zhang.

Initiated the project concept & research question
Designed the Zhangcao Village pilot (2025)
Raised 10,936 RMB for vaccination support
Developed the Dandelion Decision Framework
Designed and completed the Beijing pre/post evaluation workflow (2026)
Built and leads the multi-role project team
Authored academic research on influenza vaccination attitudes
Drafted a proposed township-scale expansion model
Connected the project with Beijing RenZe Foundation public filing materials

Research & Framework Design

Kaylee identified the China-US vaccination gap as a research puzzle. She developed the Dandelion Decision Framework by synthesizing field observations with behavioral science.

Field Implementation (Jul 2025)

In Zhangcao Village, Kaylee organized the pilot, prepared bilingual materials, led on-site delivery, coordinated with village and county stakeholders, and documented field observations.

Beijing Activity & Survey (Jun 2026)

Kaylee designed the Beijing activity as a structured pre/post evaluation workflow.

Team & Volunteer Coordination

The project operates with a multi-role team spanning digital operations, visual design, content, documentary production, and field coordination.

Resource Mobilization

Kaylee raised 10,936 RMB to support student vaccination and health education, and proposed practical mechanisms to improve school-clinic-community coordination.

Next-Phase Scale-Up Design

From one village (2025) to a completed Beijing evaluation workflow (2026) to a proposed township expansion model.

Leadership in Action

The Beijing activity shows Kaylee's leadership as a working system.
