ALBANY: Flu vaccines may prove ineffective when scientists fail to anticipate how the virus may mutate, according to a new study. Currently, scientists develop vaccines based on the dominant strain at the end of the previous flu season. However, an analysis of 209 residents across New York state found the dominant virus may change through exposure with other strains, rendering vaccines ineffective. The study conducted by The Institutes of Genome Research with the state Health Department's Wadsworth Center was published yesterday in the journal Nature and also posted online earlier this month on the journal's Web site. A new, unanticipated

dominant flu virus emerges when two strains are exposed to each other, said Elodie Ghedin, the study's lead researcher at Maryland-based TIGR.
