The Dandelion Project studies how trust, perception, and access shape real-world health decisions.
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.
A behavioral model for understanding why prevention is available, but not always chosen.
Trust shapes whether health information is accepted, ignored, or questioned.
Preventive action depends not on objective risk, but perceived risk.
Even when trust and perception align, action fails if access is difficult.
Preventive behavior becomes possible only when trust, perception, and access all align.
“Prevention is chosen when belief, urgency, and practicality align.”
The Beijing session translated the Dandelion framework into a complete field workflow.
Matched pre/post responses were compiled from the Beijing activity.
The vaccine-risk item increased from 23/80 before the session to 80/80 after.
All valid post-session responses selected the positive option.
Public coverage of the Beijing activity provides external validation.

Anonymous baseline questionnaire.
Items covered reliable information, prevention, vaccination, and sharing intention.
Post-session items documented understanding and satisfaction.
Privacy and safety note: questionnaire images are shown as anonymous project evidence.
Many parents showed clear understanding of influenza transmission and vaccine benefits. However, hesitation remained when actual vaccination was discussed.
Knowledge alone is not sufficient to drive preventive behavior.
Parents were strongly influenced by local doctors, family members, and community figures — not generalized health messaging from distant authorities.
Trust is built through relationships, not information delivery alone.
Without stronger coordination from schools, clinics, or community structures, many families delayed or avoided decision-making altogether.
When action requires individual effort at every step, inaction becomes the default.
Some parents underestimated influenza severity; others feared vaccine side effects more than the disease itself.
Perceived risk, not objective risk, often drives behavior.
Even when parents seemed open to vaccination, small constraints — time, logistics, uncertainty — often disrupted follow-through.
Behavioral friction, even when minor, can substantially reduce uptake.
These field observations challenged the assumption that awareness alone drives action.
Three phases, each building on the last.
Independently initiated and led by Kaylee Zhang.
Kaylee identified the China-US vaccination gap as a research puzzle. She developed the Dandelion Decision Framework by synthesizing field observations with behavioral science.
In Zhangcao Village, Kaylee organized the pilot, prepared bilingual materials, led on-site delivery, coordinated with village and county stakeholders, and documented field observations.
Kaylee designed the Beijing activity as a structured pre/post evaluation workflow.
The project operates with a multi-role team spanning digital operations, visual design, content, documentary production, and field coordination.
Kaylee raised 10,936 RMB to support student vaccination and health education, and proposed practical mechanisms to improve school-clinic-community coordination.
From one village (2025) to a completed Beijing evaluation workflow (2026) to a proposed township expansion model.
The Beijing activity shows Kaylee's leadership as a working system.
Kaylee translated the framework into a teachable course.
Volunteers helped with forms, participant flow, and one-on-one explanations.
The team supported residents during the questionnaire process.
