COPENHAGEN, Denmark – The queen of Denmark and the king of Spain both tested positive for the coronavirus despite being vaccinated, their respective royal houses announced Wednesday.

Denmark’s Queen Margrethe, 82, has mild COVID-19 symptoms and has isolated herself in the Copenhagen palace where she lives, the palace said.

Margrethe tested positive for the virus on Tuesday evening and canceled a planned vacation in Norway that was set to begin Wednesday, the royal household said.

The announcement came weeks after Margrethe marked her 50 years on the throne of Europe’s oldest ruling monarchy. Some of the planned festivities were postponed until September due to the pandemic.

However, the queen participated in some jubilee events this month, including a wreath-laying at the grave of her parents at Roskilde Cathedral, where Danish royals have been buried since 1559. She also met with the government and attended a reception at Parliament.

Like Margrethe, Spain’s King Felipe VI was vaccinated against the coronavirus. The 54-year-old monarch was tested for the virus after he developed “mild symptoms” of COVID-19, the royal house said.

It added that his “overall health” was fine and he will remain in isolation for seven days, following national health protocols. The royal house said that Queen Letizia has not shown any symptoms.

With 90 percent of its population over age 12 years old having received at least two doses of a coronavirus vaccine, Spain is starting to roll back health restrictions as the latest surge driven by the omicron variant ebbs.
