Types of costs in immunization • Vaccine purchase • Vaccine administration • Non-vaccine costs
Federal Contract Prices for Vaccines Recommended Universally for Children and Adolescents 1985, 1995, 2006 $1182 $155 $45 Federal contract price shown for 1985 and 1995 are averages that account for price changes within that year.
Sources of financing childhood immunizations • Government • Federal • State/local • Insurance • Private • Public • Out-of-pocket
317 Immunization Program 317 grants support: • Purchase of vaccine for free administration at local health departments • Immunization delivery • Surveillance • Communication • Education
Percent Increase of the Cost of Full Series vs. Percent Increase of Section 317 Appropriation 2005 estimate includes one dose of MCV4 and one dose of Tdap in adolescents.

How Public Health Reaches Children through VFC • VFC program has 45,000 provider sites • 75% of sites are private providers • 25% are public sector sites • Collectively, VFC providers vaccinate 90% of children • VFC vaccine for VFC-eligible children • Private purchase vaccine for other children • Improving VFC providers’ practices improves vaccinations for almost all children
Contrasts Between317 and VFC Funding Sources * Underinsured only at Federally Qualified Health Centers and Rural Health Clinics
VFC and Section 317 Vaccine Funding to Immunization Programs
Two-Tiered State Vaccination Policies at Local Health Departments • Traditionally, health department clinics vaccinated any child brought for vaccination • Underinsured children ineligible for VFC vaccine except at FQHCs and RHCs (~3,000 clinics) • VFC designated FQHCs and RHCs as safety-net providers for underinsured children • State and 317 funding used for underinsured • Due to inadequate state/317 funding, many states cannot purchase vaccine for underinsured children • Result is a two-tiered policy • Government purchased vaccine not available to underinsured at health department clinics • Access to new vaccines for some based on insurance • Ethical tension for public health officials and providers
Two-Tiered States: 2005 • Invasive pneumococcal disease • 13 states did not purchase PCV7 vaccine for underinsured children in health department clinics • Invasive meningococcal disease • 31 states did not purchase MCV4 vaccine for underinsured children in health department clinics • These states do not have a public health department safety net to vaccinate children against these diseases
Grantees Provision of Vaccines to Underinsured Children, 2006 (N=49) Source: Grace Lee et al; Harvard University
Private insurance for childhood immunizations • Approximately 53% of children <5 in 2003 • Approximately 10% considered uninsured • Most insurers cover ACIP vaccines within approximately 3 months • Many require provider to purchase vaccine – up-front costs for inventory • Reimbursement may take some time and may not cover true cost of purchase
Public insurance for childhood immunizations • Medicare • Medicaid • CHIP • Medicaid enhancement • S-CHIP
Out-of-pocket expenses for childhood immunizations • Primarily with underinsured children • Providers may refer to health departments • Exacerbated by costs of newer vaccines • May be further exacerbated by efforts to make HPV mandatory without assuring that all children have access to vaccine in public sector
Inequities in vaccine purchase - causes • Underinsurance • Inability of 317 and state/local funds to keep up with increasing vaccine costs • Burden on private providers to make large advance investments in purchasing new vaccines • Ethical dilemma at both state and provider levels
Inequities in vaccine purchase – some possible solutions • Increase 317 appropriations • Expand access to VFC for underinsured • Allow access to VFC for S-CHIP • Assure providers are fully reimbursed for purchase costs • Allow delayed payments to vaccine manufacturers/distributors
Vaccine administration • Studies indicate that it costs approximately $18-25/injection to administer vaccines • VFC does not reimburse for vaccine administration • Widely varying rates of reimbursement from Medicaid and private insurers
Inequities in vaccine administration reimbursement • Some possible solutions • Reimbursement from VFC • Minimum/recommended reimbursement rate from CMS • Negotiation with private insurers
Non-vaccine costs • Include costs of • Acquiring vaccine • Storing vaccine • Handling vaccine • Loss of vaccines • Infrastructure • Insurance
Inequities in non-vaccine costs - causes • 317 can support HD costs • VFC supports infrastructure and program costs; administration fees, in theory, include non-vaccine costs • However, Medicaid establishes reimbursement rate • Private insurers typically do not include non-vaccine costs in calculating reimbursement rates
Inequities in non-vaccine costs – some possible solutions • CMS establishes minimum or recommended reimbursement rate • Private insurers encouraged to include non-vaccine costs in reimbursement calculations
What is being done • AAP Task Force on Immunization • NVAC Financing Work Group • IDSA workgroup on adult and adolescent immunization • AMA/AAP/IDSA National Immunization Congress
Recommendations from Immunization Congress - 1 • Work with FQHCs to delegate authority to public health clinics to serve underinsured through VFC • Obtain data on cost of delivering vaccines in private practice setting and use data to educate payers and advocate for better payment • Work with manufacturers/distributors to obtain more favorable terms for payments for vaccine inventories
Recommendations from Immunization Congress - 2 • Better define components of CPT codes for immunization administration • Examine potential role of tax credits for insurers or employers in eliminating underinsurance • Create working group to explore possibility of federal vaccine purchase or funding mechanism
Recommendations from Immunization Congress - 3 • Obtain from CMS the data that led to current Medicare administration fee and use data to advocate at state level for enhanced payment • Collect data on true cost of obtaining/delivering combination vaccines as opposed to individual vaccines • Disseminate information on best business practices to minimize vaccine and administration costs

Differentiating characteristics of childhood and adult immunization • Delivery system infrastructure • Financing mechanisms • Highly effective vaccines preventing recognizable diseases • Patient/parent/societal expectations • Provider attitudes • Leadership of state/local health departments and CDC
