My counterpart at Public Health Seattle-King County, Dr. Jeff Duchin, who is a highly regarded expert in the realm of infectious diseases and epidemiology, wrote this week about the effectiveness of this year's flu vaccine and I wanted to take a moment to echo his sentiments.
Early reports out of the Southern Hemisphere are indicating that one component of the flu shot, for influenza A H3N2, may have only been 10% effective in Australia. Dr. Duchin points to several reasons, that I agree with, why Australia's situation is not necessarily predictive of what we should expect here. And most importantly, both of us, and numerous experts are still strongly recommending getting the flu shot.
