Vaccino Coronavirus, Moderna pubblica protocollo della sperimentazione: mai successo prima
L’azienda ha preso una decisione senza precedenti scegliendo di rendere pubblico lo studio che sta conducendo su 30mila pazienti con l’obiettivo di raggiungere un’efficacia del 60% contro il Covid-19. Una percentuale molto alta per Roberto Burioni: “Firmerei con il sangue”

Nonostante l’importanza di studi come questo, resta chi potrebbe chiederne l’interruzione per motivi etici, spiega Roberto Burioni: "Se ci si accorgesse che nessuno dei vaccinati si ammala e diversi dei non vaccinati si ammalano, con una forte validità statistica, sarebbe non etico privare chi è stato vaccinato per finta del vaccino vero"

The vaccine will be based on two components : the protein which is on the surface of the coronavirus, called the spike protein that researchers express in the lab and then attach it on the surface of a virus-like particle.

Tra le ipotesi c’è anche quella contraria, ovvero che tra i vaccinati si registrino effetti collaterali gravi, o una malattia più grave e in questo caso sarebbe inaccettabile continuare a vaccinare i partecipanti

"La fretta in questo caso è una cattiva consigliera – ha detto Roberto Burioni - Intanto teniamo duro, usiamo le mascherine, manteniamo le distanze, evitiamo i luoghi affollati e se le cose vanno bene questo è l'ultimo inverno con questo virus tra i piedi in modo massiccio. Poi ci rifaremo"
