Denmark is developing a digital "vaccine passport" for people who have received a COVID-19 vaccine, a move that may enable them to travel to countries where such documentation is required during the pandemic.
"It is expected that there may be requirements from other countries to present vaccine documentation upon entry. A Danish vaccine passport can be used here," the Health Ministry said in an emailed statement on Friday.
The passport may be rolled out in the first months of this year to be accessed through the Danish public health website, the ministry said. It was not clear whether the passport would be available via an app.
