  1. NA Not Applicable
  2. a “Practice” indicates the vaccinations’ administration setting other than SLIV clinics, almost always (> 95%) primary care practices [16]
  3. b Cost components (Subtotal cost or Total cost) are defined in Table 2
  4. c SLIV: School-located influenza vaccination
  5. d “Anywhere” includes both vaccinations administered at the SLIV program and those in “practices.” “Practice” indicates the vaccinations’ administration setting other than SLIV clinics, almost always (> 95%) primary care practices [16]
