Finland's last coronavirus restrictions will be lifted once 80 per cent of over-12s have been fully vaccinated, the government has said, a target it expects to reach by October.

“Our aim is to open up society and keep it open,” Prime Minister Sanna Marin told reporters in Helsinki after a cabinet meeting on the country's coronavirus strategy, Reuters reported.

“The advancing vaccination coverage is our key to achieving that,” Marin said, adding that restrictions will be lifted gradually as the virus situation improves.
