The Cardano for Covid-19 Project (CFC19)

Long time not posting in this forum.
I’m writing this projects because I think it’s possible for Cardano Foundation to make real contribution to real world.
I want to make an apps in Android that can detect when and where one can get Covid-19 Vaccine by ID-ing using Fingerprint censor in each cell phone that one use. And All data will be store in Cardano blockchain.
This Data will be against the vaccine availibility from the government data or any vaccine manufacturer ID. And since it was ID with fingerprint. We will know if one already have it or not by just using ANY cell phone that have fingerprint censor at it’s back.
Seems simple right? Any Idea how to start? And is this applicable in Cardano blockchain condition today?
Please give some comments or advise.
