Beijing Daxing International Airport has inoculated nearly all its staff members and aircraft crew with COVID-19 vaccines as of Tuesday, according to the airport management authority.

On Tuesday morning, the general manager of the Hotel Kapok, located inside the airport, and head of the vaccine team in the airport, put up a safe and secure sticker on the hotel's front desk. It also was a special sign that designated staff as the first group among Daxing district departments to be vaccinated.

For the next step, the airport management center will vaccinate those who haven't been inoculated to ensure a safe and secure environment for airport passengers.

According to local district authorities, about 1,487 enterprises and individual businesses in Daxing have been labeled with the safe and secure sticker, indicating that over 80 percent of people in these places were vaccinated.

"About 100 to 200 passengers went in and out here. Thus all service staff of our office were vaccinated very early," said Sun Wei, a manager in the airport's Lost and Found Office.
