The vaccine for adolescents aged 15-17 years is the same as that for adults, and is inactivated. However, unlike adults, adolescents aged 15-17 need to be accompanied by their parents or guardians for the New Guan Vaccine and actively inform the doctor if they have a history of drug allergies and certain special diseases such as congenital heart disease, active tuberculosis, skin diseases, etc. Avoid fasting before vaccination. Bring valid documents and wear loose clothing on the day of vaccination. After vaccination, stay at the injection site for 30 minutes for observation, so that you can be treated promptly if you experience any uncomfortable symptoms. Usually, the general reactions of adolescents aged 15-17 after vaccination are mainly fever, local pain, redness and swelling; abnormal reactions are mainly allergic reactions, mainly allergic rashes, which are relatively mild and can be relieved by themselves without treatment. In addition, you should keep the vaccination site clean and dry, and avoid scratching and massaging the injection site with your hands to avoid infection. Keep your diet light, ensure sufficient sleep, and avoid strenuous exercise. After vaccination, you should still take good personal protection, wash your hands regularly, wear a mask and maintain good personal hygiene.
