After vaccination, WeChat or Alipay will generally be displayed within two to three days after vaccination, depending on the registration system in each region. It may be faster in some places, but it will be shown the next day after vaccination. Some places may slow down, and it will not appear until a week after vaccination, which shows that these are relatively normal.
At present, the health code has been well combined with the vaccination in COVID-19. You only need to open Alipay and search for the health code to query your vaccination records in COVID-19. Open the Alipay APP on your mobile phone, enter "health code" in the search box of Alipay homepage to search, or click "health code" in the quick application of Alipay homepage.
