The article discusses the study of the effectiveness of influenza vaccination in Marshfield, Wisconsin. Results showed that infuenza was detected by reverse transcription-polymerase chain reaction (RT-PCR) in 191 patients. The overall interim estimate of vaccine effectiveness (VE) was 44%. Charts are presented that show the number and percentage of patients with medically attended acute respiratory illness who were enrolled in the study and tested for influenza.
