Can a Genetic Model Predict Next Year’s Flu Strain?

The Los Angeles Times reports that researchers “analyzed the genetic code of thousands of strains of Influenza A that occurred over a 44-year period to create a model that accurately predicts” the evolutionary fitness of strains. The study examined Influenza A/H3N2, focusing on the hemagglutinin protein responsible for binding the virus to human cells. The model identified the correct lineage of strains in 93% of cases based on previously recorded data on flu strains from 1968 to 2012 and “chose a more genetically matched strain than the one deployed as a vaccine.”
