In addition, since the city began offering vaccines to foreigners this month, local authorities found it took longer to register foreigners' visa information, as different countries' passports have different formats and proofreading takes longer, so "we have decided to begin registering all their information online one day ahead before arriving at the hospital," a staff member in registration services said.

According to Gu Qing, director of Tianjin's Municipal Center for Disease Control and Prevention, a total of 6.5 million local residents have received the vaccination to date, and 70 percent of local residents aged from 18-59 have received their first dose.

"More special sessions for foreigners will be held," he said.
