It is possible to administer the New Crown vaccine off-site, but it is not recommended that vaccination be administered across regions, and it is best to complete the vaccination in one place if possible. After the first vaccination, an electronic record of the vaccination will be created in the place of vaccination, so that the vaccination record can be checked in the future. Therefore, when you receive the second vaccination, even if you are not in the place where you received the first vaccination, you can still find out the status of the first vaccination by searching for the vaccinee’s e-record on the Internet. However, sometimes the second vaccination may be affected due to network problems in different places and different manufacturers, brands and batch numbers of vaccines. Therefore, if the vaccination is done in a different place, it is better to bring along the vaccination certificate (such as paper or electronic version) and ID card to facilitate the comparison with the Internet.
