Its public health authority said that people who had previously been infected with Covid-19 develop an immune response similar to that bestowed by a vaccine dose, and that a single dose after infection would likely suffice.
Meanwhile, the head of the EU's ECDC health agency, Andrea Ammon, told AFP on Friday that the world should be prepared for the coronavirus to continue to circulate long-term despite the roll-out of vaccines.
"We should be prepared that it will remain with us," the head of the Stockholm-based European Centre for Disease Prevention and Control said in an interview.
"It seems more likely that it would stay. It seems very well adapted to humans," she said.
"It wouldn't be the first virus that is with us forever, so it's not an unusual feature for a virus."
