Additional dose and booster dose
The ministry’s circular on the third additional dose of the anti-Covid vaccine therefore distinguishes between “additional” doses and so-called “booster” doses. For additional dose, we read, “we mean an additional dose of vaccine to complete the primary vaccination cycle, administered in order to achieve an adequate level of immune response”.
Per dose «booster», on the other hand, “we mean a booster dose after the completion of the primary vaccination cycle, after a certain time interval, administered in order to maintain or restore an adequate level of immune response over time, in particular in populations characterized by a high risk, due to frail conditions associated with the development of serious or even fatal disease, or due to occupational exposure “. The booster dose should be administered at least six months after the last dose. At the moment, according to the indications of the CTS, the circular specifies, “the administration of the additional dose is considered a priority in transplanted and immunocompromised subjects”.
Without prejudice to the priority of achieving high vaccination coverage with the completion of currently authorized courses, “the strategy for administering a dose will be defined «booster» of m-RNA vaccine (Comirnaty of BioNTech / Pfizer and Spikevax of Moderna) in favor of further target groups, starting with those mentioned above, taking into account the scientific evidence and the evolution of the epidemiological scenario “.
