Un nuovo vaccino in grado di proteggere i vitelli dal virus respiratorio sinciziale bovino (RSV): è la scoperta fatta dall’Istituto di Ricerca in Biomedicina dell’USI, insieme al britannico Pirbright Insitute e alla Humabs BioMed SA, azienda svizzera attiva nello sviluppo e scoperta di anticorpi a scopo terapeutico.
Nei vitelli, il virus RSV è associato a malattie respiratorie gravi ed alta mortalità, per un costo annuo stimato in un miliardo di dollari. Esistono dei vaccini in commercio, ma sono poco efficaci mentre quello appena scoperto – si legge in un comunicato – è basato su una proteina stabilizzata geneticamente e “in grado di indurre una completa protezione”.
La scoperta apre la via alla produzione di un vaccino analogo per l’uomo, in quanto la malattia che colpisce gli animali è strettamente legata al virus RSV umano, che causa gravi bronchioliti e polmoniti nei neonati, persone anziane e soggetti con deficienze immunitarie. Infezioni che causano 250'000 decessi ogni anno e contro le quali non esiste, attualmente, una protezione efficace.
