Un vaccino influenzale universale, prodotto in modo più semplice e immediato rispetto a quelli attuali. È questo il senso della scoperta scientifica dell’Istituto di ricerca in biomedicina (IRB) pubblicata domenica sulla rivista Nature.
“Abbiamo scoperto che è facile creare un certo tipo di anticorpi in grado di bloccare tutti i virus influenzali”, spiega il direttore dell’IRB, Antonio Lanzavecchia. “Poiché alcuni anticorpi sono rari, pensavamo fosse difficile produrli. Si credeva che servissero diverse mutazioni. In realtà la prima è quella che rende l’anticorpo potente e in grado di neutralizzare i virus”.
Un vaccino, insomma, in grado di stimolare la formazione dell’anticorpo giusto. L’équipe dell’istituto con sede a Bellina sta ora lavorando alla sua produzione. Nessuno, però, si sbilancia sui tempi per completare la ricerca.
Allo studio hanno collaborato una società biotech privata svizzera (spin-off dell'IRB), l'Ospedale San Raffaele di Milano e una multinazionale farmaceutica.
