Figure 2. — Historical^10-14 and projected influenza vaccine coverage by age group. Historical vaccine coverage data were available through 2012, and data were not available for every year for children aged <18 years; therefore, vaccination coverage estimates for future years and for years without historical estimates were projected using regression techniques and available historical data. Exponential and logarithmic functions were tested, and best-fit functions were selected for each age group.
