The Technical Scientific Commission (CTS) of Aifa, which met this morning, gave a favorable opinion on the ‘booster’ dose with an mRna vaccine starting from 6 months after the first dose with the Johnson & Johnson vaccine. In the afternoon, the green light from the Italian Medicines Agency (Aifa) arrived. Almost one and a half million Italians vaccinated with J&J. The booster will be done six months after administration, with an mRna vaccine, i.e. Pfizer or Moderna.
The Technical Scientific Commission found that the data available for the J&J anti-Covid vaccine indicate a “substantial stability of the immune response, both humoral and cellular, up to 8 months after the administration of a dose of Janssen vaccine. Also protection against serious illness, hospitalization or death is substantially stable up to at least 6 months after vaccination. At the same time, however, with the passing of the months there is a slow decline in vaccination efficacy against mild / moderate forms of the disease “.
Furthermore, Nicola Magrini, director general of the Italian drug agency, told “Tg1” that Aifa “today also reasoned about opening the possibility of a booster dose for vaccinated people with other vaccines such as Sinovac and Sputnik: these vaccines they will have this possibility. This decision – he added – I believe will facilitate the acquisition of the Green Pass “.
