The German city of Cologne and Cologne/Bonn Airport offered an unusual vaccination experience, by converting a Airbus A300 Zero G plane into a vaccination center for children aged 5 to 11.
After getting their jab, children and parents were given a tour of the plane's cockpit and a chance to take photographs.
Until 2014, the Airbus A300 Zero G was used to simulate weightlessness as a so-called parabolic aircraft and was used for test and experimental flights.
Parents said getting vaccinated on the plane was an exiting alternative to a doctor's office.
9-year old Jonas Baumgarten said it was "cool".
Germany's independent vaccination advisory panel is recommending vaccination for children age 5 to 11 with pre-existing conditions or who are in close contact with vulnerable people.
Children in this age group should receive two doses of the Pfizer-BioNTech vaccine three to six weeks apart, the panel said.
