Digital vaccine passports being developed by the WHO and Estonia

Tech-savvy Estonia is taking the lead in the global effort to develop digital vaccine passports.

Alongside the World Health Organization and Estonian company Guardtime, Estonia is working on a pilot project on how globally recognized electronic vaccine certificates might work, titled “VaccineGuard.”

The scheme will explore the possibility of a “smart yellow card” – a digital version of an existing paper system to prove yellow fever vaccination.

As various countries pursue their own digital vaccine certification, the WHO has so far not recommended vaccine passports for travel. Although that could change, depending on the results of the program with Estonia.

Anett Numa, an expert on digital transitions at the e-Estonia Briefing Centre, says that trust, both between participating nations and between individuals and institutions organizing the vaccine passport, is key.

The vaccine passport would rely on each individual country’s input.
