(CNN)Sweden has revealed that despite adopting more relaxed measures to control coronavirus, only 7.3% of people in Stockholm had developed the antibodies needed to fight the disease by late April.
The figure, which Sweden's Public Health Authority confirmed to CNN, is roughly similar to other countries that have data and well below the 70-90% needed to create "herd immunity" in a population.
It comes after the country adopted a very different strategy to stop the spread of coronavirus to other countries by only imposing very light restrictions on daily life.
Sweden's chief epidemiologist Anders Tegnell said the number was a "little lower" than expected "but not remarkably lower, maybe one or a couple of percent."
