We showed previously that a single intranasal vaccination of mice
with a recombinant vesicular stomatitis virus (VSV) expressing an
influenza virus hemagglutinin (HA) protein provided complete protection
from lethal challenge with influenza virus (A. Roberts, E. Kretzschmar,
A. S. Perkins, J. Forman, R. Price, L. Buonocore, Y. Kawaoka, and
J. K. Rose, J. Virol. 72:4704-4711, 1998). Because some
pathogenesis was associated with the vector itself, in the present
study we generated new VSV vectors expressing HA which are completely
attenuated for pathogenesis in the mouse model. The first vector has a
truncation of the cytoplasmic domain of the VSV G protein and expresses
influenza virus HA (CT1-HA). This nonpathogenic vector provides
complete protection from lethal influenza virus challenge after
intranasal administration. A second vector with VSV G deleted and
expressing HA (

the advantage of not inducing neutralizing antibodies to the vector itself.
