“Yes to a fourth dose of Covid vaccine for immunosuppressed people”, for which it will technically be a post-primary booster of two doses plus an additional dose. As for a ‘booster booster’ for everyone, “at this moment it is not feasible in terms of acceptance and organization”, as well as not supported by sufficient evidence, as repeatedly stressed by the European Medicines Agency Ema. Thus the virologist Fabrizio Pregliasco, lecturer at the State University of Milan, comments to the Adnkronos Salute the green light from the Aifa Technical Scientific Commission to a call for severely immunocompromised patients.
But if today the fourth dose is not a realistic prospect for the general population, the expert repeats that “a probable periodicity of vaccination against Covid-19 is a destiny, at least when updated products will be available in the near future” to the new circulating variants of the coronavirus Sars-CoV-2.
So what we will all probably do will not be a fourth dose, but the first of a new vaccine? “The shift – confirms Pregliasco – will be towards a vaccination approach like the one we have for influenza, based on the recommendation” addressed in particular to the categories at greatest risk.
