Abstract excerpt
Mutant recombinant respiratory syncytial viruses (RSV) which cannot express the NS1 and M2-2 proteins, designated rA2DeltaNS1 and rA2DeltaM2-2, respectively, were evaluated as live-attenuated RSV vaccines. The rA2DeltaNS1 virus contains a large deletion that should have the advantageous property of genetic stability during replication in vitro and in vivo. In vitro, rA2DeltaNS1 replicated approximately 10-fold...
