[h=3]Abstract[/h] The ongoing influenza epidemic is characterized by intense activity with most influenza infections due to the A(H3N2) viruses. Using the screening method, mid-season vaccine effectiveness (VE) in preventing influenza-like illness in primary care was estimated to 32% (95% CI; 23 to 40) among risk groups and was 11% (95% CI; -4 to 23) among the elderly (≥65 years). The VE in ≥65 years was the lowest estimate regarding the four previous seasonal influenza epidemics.
