Introduction

In general, whether students need a booster shot after receiving the COVID-19 vaccine should be determined based on individual health conditions. If in doubt, it is recommended to consult a professional medical institution or disease control center. After vaccination, keep the injection site dry and clean, avoid strenuous exercise, maintain a light diet, ensure adequate sleep, and seek medical attention promptly if experiencing adverse reactions such as rash or fatigue, informing parents immediately.

In general, whether students need to receive a booster dose after completing their initial COVID-19 vaccination should be determined based on individual health conditions. If in doubt, it is recommended to consult a professional medical institution or disease control center. The detailed analysis is as follows:

After students have completed their primary vaccination series, if they are in good health without underlying medical conditions and the required interval since their last dose has passed, they may receive a booster shot. At this point, the level of existing antibodies in the body may have declined over time; a booster dose can rapidly increase antibody concentration and enhance immune protection. Given the crowded nature of school environments, receiving a booster helps reduce the risk of infection and transmission, providing stronger protection for normal study and daily life.

If a student is currently experiencing an acute illness, such as fever or coughing, or has had a severe allergic reaction to a previous vaccine component, they should not receive the booster dose. During an acute illness, immune function is unstable and vaccination could worsen symptoms. Individuals with known allergies may face serious risks upon exposure to allergenic components.

After vaccination, keep the injection site clean and dry, avoid strenuous exercise, maintain a light diet, ensure adequate sleep, and promptly inform parents and seek medical attention if any adverse reactions—such as rash or fatigue—occur.
