Vaccsbook is Trans-National
Instead of separate, unintegrated systems in each country or health system,
Vaccsbook is a single system with a single database handling all people in all nations.
It can be accessed from anywhere in the world.
If someone travels or migrates, their vaccination history is always
with them, accessible from anywhere (that has electricity), with
their future vaccination needs automatically recalculated according to the
schedule of their current location.
