The Greek PM announced at the end of June that those aged between 18 and 25 would be eligible for a €150 cash card, and a free month of mobile data when they receive their first Covid vaccination. According to Reuters:
"With the first jab of the vaccine (they) will get a prepaid card of
150 euros," Prime Minister Kyriakos Mitsotakis told a ministerial
meeting.
"It's a debt to the youth, a gift out of gratitude," he added.
Around 940,000 Greeks aged 18-25 who get their first shot by the end
of the year will be eligible for the "freedom pass" cash bonus, the
government said.
On the first day of residents being able to apply for this card, there were more than 120,000 applications, according to Tornos News. It looks like the card can only be used on travel and entertainment though, rather than it being a pure cash lump sum:
It can be used to cover costs in travel and entertainment, such as
plane and ferry tickets, hotel bookings, music, theater and cinema,
museums, and archaeological sites that have opened, most available
only to the fully vaccinated.
