You need to go to the local community health service center (that is, the place where children are vaccinated) to find a doctor to prescribe it for you, and you need a vaccination certificate. These are all the proofs needed for going to school.
According to the relevant laws and regulations of the state, the state implements the planned immunization system, and the state implements the vaccination certificate system for children, that is, within one month after the child is born, his guardian should apply for the vaccination certificate at the vaccination unit where the child lives. When children enter kindergartens and schools, nurseries and schools shall examine vaccination certificates.
Most vaccines have strict vaccination intervals. If there is no child vaccination certificate, parents can't provide the name and specific vaccination time, and it is unreliable to rely solely on memory. Therefore, parents should promptly handle and properly keep their children's Children's Vaccination Certificate, pay attention to the appointment time on the Vaccination Certificate, and vaccinate on time.
If you can't take your child for vaccination on time due to illness, going out and other reasons, you should take the initiative to replant your child on the next vaccination day. Children who migrate, go out or live in different places for some reason can continue to complete the prescribed vaccination at the vaccination clinic in the migration place with the child vaccination certificate. When children's basic immunization and supplementary immunization are all completed, parents should keep their children's vaccination certificates for their children to check when they enter kindergartens, schools, join the army or enter and leave the country in the future. If it is lost, please reissue it in time to avoid trouble during vaccination.
