Can people under 18 years old receive the third dose of vaccine?

Generally, whether individuals under 18 years of age can receive a third vaccine dose depends on the type of vaccine and the purpose of vaccination. The details are as follows:

If the vaccine is a COVID-19 vaccine, certain types have been approved for administration of a third booster dose to individuals aged 12–17. Particularly for adolescents with compromised immune systems or those who have completed their primary vaccination series after the required interval, a booster may be administered following medical evaluation to enhance immune protection. This recommendation is based on safety and efficacy data, along with an assessment of infection risks in adolescents.

If the specific vaccine has not been approved for use in individuals under 18, or if the adolescent has contraindications such as a history of severe allergy or is currently experiencing an acute illness, or if the vaccination is not deemed medically necessary, then the third dose should not be administered. In these cases, the risks of vaccination may outweigh potential benefits due to insufficient suitability of the vaccine or individual health conditions.

After vaccination, keep the injection site clean and dry, and avoid scratching to prevent infection. Maintain a light diet, avoiding spicy or irritating foods, get adequate rest, and refrain from strenuous exercise. If symptoms such as redness, swelling, or fever occur, promptly inform parents and seek medical attention.
