At present, many places need to inquire about health codes and vaccination. As long as they are vaccinated, the health code will be displayed. If the health code has not changed after vaccination in COVID-19, the official response is that many areas have implemented vaccination policies, and the display of "health code" is delayed due to the delay in uploading vaccination information. Some vaccination institutions sometimes don't upload records so quickly, so they can't be vaccinated temporarily.
At the same time, if the vaccination information has not been uploaded, the health code can only be displayed normally after uploading the information again. However, if the situation cannot be continuously displayed, it is recommended to call the relevant local departments to find out the specific reasons.
