Vaccine advisers to the US Food and Drug Administration are scheduled to meet Thursday to discuss the second coronavirus vaccine aimed at the US market, this one made by biotechnology company Moderna. The Moderna vaccine is very similar to Pfizer's and BioNTech's vaccine. Both use a new approach involving genetic material known as messenger RNA or mRNA. "Really, they do seem quite similar," added Malkin, who has studied both the Pfizer and the Moderna data. "Tomorrow, the FDA will hopefully make a decision regarding whether or not the Moderna messenger RNA vaccine will get an emergency use authorization," Fauci said on CNBC.
