Estimated influenza vaccine effectiveness for children in Alachua County, Florida, USA, as compared with Florida Region 3, and Florida as a whole*

Age group, y Influenza season Region 3, % (95% CI) Florida, % (95% CI)
5–17 2012–13 71 (67–76) 73 (68–78)
2013–14 73 (68–79) 77 (72–82)

*Estimates are based on reports of influenza-like illness from emergency departments reported through Florida’s Electronic Surveillance System for the Early Notification of Community-based Epidemics. See Tran et al. (11) for detailed methods. Region 3 and Florida are comparison areas, so they exclude Alachua County data.
