The second doses of vaccines were seen being administered in Beijing's Shijingshan district in an orderly manner on Monday. At the newly-built Yamenkou vaccination site in Shijingshan district, residents were lining up with a distance of one-meter between them under guidance from medical staff, completing the pre-check and registration process to receive the Sinovac vaccine. GT reporters observed that unlike the first dose, medical staff during the administration of the second dose would carefully ask those receiving the vaccines about the vaccine category, location of their first shot, and whether there were any adverse reactions.
