Press release no 681 - In its extraordinary meeting held on 5 January 2022, upon request by the Ministry of Health, AIFA’s Technical Scientific Commission (CTS) expressed its positive opinion on the possibility to administer a booster dose also to people aged 12 to 15 years. As already established for the 16-17 age group and for vulnerable people aged 12-15 years, this booster too should be carried out with Comirnaty. Concerning the time interval between the primary vaccination course and the administration of the booster dose, in the absence of specific data for this age group, the CTS considers it reasonable to maintain the same criteria as in adults. The effectiveness and safety of the booster dose in the 12-15 age group will be subject to constant monitoring. Finally, it is reiterated that the completion of the primary vaccination course for the entire eligible population remains the primary objective of the vaccination campaign.
