The third dose of Kexing vaccine has not been opened yet, so we can&;t make an appointment. We can only make the first and second shots. The specific appointment process is as follows (take Changsha, Hunan as an example): Step 1: Pay attention to WeChat official account, a resident health card in Hunan Province, and click the health card in the bottom corner. Step 2: Vaccinate at the far right of the health code. Step 3: Enter the vaccine appointment interface and click on the vaccine appointment. Step 4: Check the nearby inoculation institutions, click Open to see if there is any vaccine, and if there is, click Appointment directly. After the appointment is successful, you can go to the inoculation point for inoculation according to the required time. It should be noted that it is best to go to the vaccination according to the specified time after the vaccine appointment is successful, but it doesn&;t matter if it is not vaccinated in time for other reasons, you can cancel the appointment one day in advance. Vaccination service app has an interruption booking mechanism, which can be locked three times for one month before re-booking.
