They are a very small part of the vaccinated population. But for them, according to the decisions of the Commission for drugs, the so-called booster with Pfizer or Moderna vaccine is needed. The Aifa commission, in fact, gave the green light to the booster 6 months after the first dose for those vaccinated with J&J: the second dose, however, will be carried out with an mRna serum.
In fact, just under one and a half million Italians are interested in the green light from the Aifa Technical Scientific Commission to recall those who have received the Johnson & Johnson single-dose vaccine. According to the latest update of the commissioner for the health emergency, in particular, the vaccinated with J&J are 1,491,635, 2.52% of the population over 12. To date, overall the people with at least one administration are 46,656,290 , 86.38% of the over 12s.
