If the injection is made locally in Guangzhou, it will be automatically uploaded to the health code. If it is an injection from other places, you need to upload the health code to Guangzhou. This is unacceptable.
At present, the vaccination system can not be communicated across provinces, but it can be identified among cities in Guangdong Province. The vaccination information of cities in Guangdong Province can be displayed in "Yuekang Code" and "Suikang Code". For vaccination information from other provinces, please keep paper vaccination vouchers or local electronic vaccination vouchers.
