These epidemics caused unusually high illness and death in young children (33,34), consistent with the antigenic drift away from both the 2007 Southern Hemisphere subtype H3N2 and H1N1 vaccine strains (33).
The genetic makeup of influenza viruses allows frequent minor genetic changes, known as antigenic drift, and these changes require annual reformulation of influenza vaccines.
Mutations S123P and S129A, R to G substitution in the HA cleavage site, and S155N and K189N mutations at antigenic site B (which could explain the antigenic drift measured) are characteristics that seem to have become established in the latest Cambodian isolates (online Appendix Table, available from www.
The antigenic homogeneity of the canine viruses suggests that measurable antigenic drift has not yet occurred.
Additionally, major antigenic drift among influenza viruses (H1N1 to H2N2 to H3N2 from 1918 to 1969) can be temporally mapped to above-ground nuclear testing in the flight paths of migratory birds across Siberia to Eastern China.
Monitoring the genetic structure of this virus is needed for predicting changes that may confer ability to cause pandemics: pathogenicity, host range, and antigenic drift.
The difficulty of creating a diagnostic device for influenza is due to the antigenic drift or mutation of the virus from year to year.
The immune responses elicited by subpotent vaccines may exert selection pressure that favors antigenic drift and shift (Figure).
Antigenic drift of H5N2 viruses belonging to the Mexico lineage, resulting in lower identity (less similarity) to the vaccine strain, has been described (16).
These findings support the notion that cats may be broadly susceptible to circulating H5N1 viruses and thus may play a role in reassortment, antigenic drift, and transmission.
Every 2 to 5 years, the accumulation of mutations results in a major antigenic drift away from the previously circulating strains (4).
