Tianjin just announced mandates that would bar unvaccinated people from most public places. Under a new mandate that took effect this week, locals are required to present two health credentials — a green health code on one’s smartphone that shows your health condition which is required to move around the city, and a vaccination certificate issued by an authorized hospital — in order to gain entry to establishments like shopping malls, supermarkets, vegetable markets, restaurants and banks. When denied access, unvaccinated individuals have to provide personal information that will be used by community workers for contact and vaccination persuasion.
