Minors need to be accompanied by a guardian, such as a parent or delegate, when receiving vaccinations. Vaccination is one of the effective ways to prevent many diseases. Vaccination should be carried out by the legal guardian with the ID card, family register or vaccination certificate booklet to the hospital or vaccination site with the knowledge and voluntariness of the vaccinator. There are certain precautions to be taken before or after the vaccination of different vaccines, which need to be carried out under legal and reasonable circumstances after careful consultation and understanding by myself and my guardians: 1. If the vaccinator has fever, cold, or various acute or chronic infectious diseases, the vaccination should be suspended, and the doctor will evaluate whether the vaccination is possible after the disease is cured or the symptoms are stabilized. 2. Precautions after vaccination: 1. After vaccination, observe the vaccination site for about half an hour to make sure there is no abnormal reaction before leaving; 2. After vaccination, attention should be paid to suspending heavy physical labor or highly stressful activities, taking appropriate rest and drinking more water while ensuring sufficient sleep; 3. In case of serious reactions after vaccination, such as high fever and generalized pain, you should inform your guardian and contact the vaccination site in time, and take measures for further treatment with the help of the vaccination site or medical personnel. If the guardian is unable to accompany the minor for vaccination, he or she can also selectively sign a power of attorney for vaccination and entrust another person to accompany him or her according to the requirements of the local medical institution.
