However, neither Vaxart nor any other business that Radspinner knows of uses the same technology as RedeeFlu. The vaccine is made up of a replicating live flu virus from which a key gene has been deleted. The vaccine virus is able to live in the body just long enough to provoke a strong immune response, but thanks to the deleted gene it’s not able to cause disease or spread to other people.
“The live virus, single-replication—we’re the only one in the game there,” Radspinner says.
