A comparison of the antigenicity and immunogenicity of ISCOM vaccines
prepared from equine influenza viruses H3N8 and H7N7 was made with ina
ctivated whole-virus vaccines containing equivalent amounts of virus h
aemagglutinin. ISCOMs stimulated superior antibody responses in terms
of both amount and duration. As with conventional whole-virus vaccines
, the levels of antibody to virus haemagglutinin induced by ISCOMs cor
related with protection.
