COPENHAGEN, Denmark — Danish health authorities says they’ll offer vaccinations at cultural events after experiencing success with one-day pop-ups in supermarkets.

“There are still a number of young people aged 20-34 who have not yet been vaccinated, and the Danish Health and Medicines Authority continues its efforts to increase vaccination support in this age group as well,” said Niels Sandoe of the National Board of Health.

He called it “incredibly positive” that 386 people were vaccinated in supermarkets last Saturday, saying it “shows that there are still citizens who want to be vaccinated when they receive a local offer.”

The pop-up vaccination will take place on Sept. 17 at the SPOT festival of Danish and Nordic music.

More than 80% of people above age 12 have been fully vaccinated. Sandoe has said Denmark’s target of 90% vaccinated by Oct. 1 is reachable.
