AB  - Last year, the influenza vaccine did not match the circulating strains very well, and its overall protective efficacy was only 40%.

Surveillance data from the Southern Hemisphere during the summer of 2008 show that this vaccine is expected to match well the circulating strains in the Northern Hemisphere.
