The idea is to have a national campaign with a bus or a trailer that travels around the country spreading the message around bone marrow donation and a website to enrich the experience. It could be the bone marrow tour!
Launching an education campaign in schools focusing the kids may be a good way of discussing the bone marrow donation process with transparency, to get the right information to the parents and prevent some barriers to appear.
What a great idea! You really captured 'my feelings'! By engaging in a challenge, everyone gets more aware of the problem and goes deeper in the subject. By doing that we address other barriers like misunderstanding and feeling rushed.
Building on this, these challenges and engagements could go beyond an online platform, and be followed by events or workshops within the community. It would feel more personal and would be a powerful experience for the community.
