Modified Influenza Virus for Monitoring and Improving Vaccine Efficiency (SJ-04-0033) |
| Description |
The inventors found that the conversion of serine at position 223 to asparagine (N223) in the HA protein of the H5N1 influenza virus increased the sensitivity of a hemagglutination inhibition (HI) assay in which this protein was used. This N223 change alters receptor specificity and/or antibody-antigen binding. The inclusion of the N223 residue in the HA proteins of diagnostic reference viruses may facilitate the evaluation of vaccine efficacy in humans. |
