U.S. population counts and immunization rates for privately insured young children and adolescents, with and without FDC for select vaccines, and effects of extending FDC for immunizations (in millions), 2008^a,b

^aApproximately 10%–11% of children were reported as having ≥2 forms of insurance.

^bAuthors' calculations pulled data from two sources: (1) the 2008 National Immunization Survey (NIS) (http://www.cdc.gov/nchs/nis/data_files_09_prior.htm) and NIS-Teen (http://www.cdc.gov/nchs/nis/data_files_teen.htm) for population counts and overall vaccination rates of privately insured children, and (2) the 2006 MarketScan database to estimate the difference in vaccination rates for those with and without cost sharing.

FDC = first-dollar coverage

MMR = measles, mumps, and rubella

PCV7 = heptavalent pneumococcal conjugate

HPV = human papillomavirus

MCV4 = meningococcal conjugate
