Childhood vaccinations can be given in a different place, but it is best to communicate with the original vaccination unit in advance to understand the relevant precautions, and then consult the Internet or telephone about the vaccination in the new vaccination place. Childhood vaccinations are scheduled at a hospital for the convenience of follow-up visits, as well as for the convenience of vaccination. After being designated at a certain hospital, the hospital will usually notify the child of the vaccination on a regular basis, or reserve the vaccine for him/her to prevent him/her from coming without the vaccine. Changing places for vaccination may involve the absence of vaccine when it is time to receive this vaccine; there are also different requirements for each vaccination site, and failure to comply with the requirements may result in unsuccessful vaccination and the need to travel several times. When children change their place of vaccination, it is possible that the place where they have been vaccinated for a long time does not have the vaccine, or that they change their place of residence. When a child needs to be vaccinated in a different place, it is advisable to inquire in advance about the documents required to be prepared in order to avoid the situation of not being able to be vaccinated.
