But while Indian health workers did perform the standard blood test for Y . pestis, which sometimes can result in nonspecific reactions, they failed to perform another test, known as hemagglutination inhibition, that rules out the nonspecific reactions.

HA and HI apply the process of hemagglutination, in which sialic acid receptors on the surface of red blood cells ( RBCs ) bind to the hemagglutinin glycoprotein found on the surface of influenza virus ( and several other viruses ) and create a network, or lattice structure, of interconnected RBC s and virus particles.

Immunogenicity was assessed by microneutralization and hemagglutination-inhibition assays with the use of the vaccine virus, although a subgroup of samples were tested with the use of the wild-type influenza A / Vietnam / 1203 / 2004 ( H5N1 ) virus . " The results of this study combined with others scheduled to be completed by Spring 2007 is hoped will provide a highly immunogenic vaccine that is cross-protective against heterologous influenza strains.
