Vaccination coverage of 2-year-old children–United States, 1991-1992

Protecting children against vaccine-preventable diseases is a national priority in public health. Because approximately 80% of childhood vaccine doses are recommended for administration during the first 2 years of life, vaccination coverage among children must be continuously monitored. National estimates of vaccination coverage were calculated annually from 1959 through 1985 but not for 1986-1990. Beginning in 1991, national estimates of vaccination coverage of preschool children have been available through the National Health Interview Survey (NHIS), a national survey of the civilian noninstitutionalized population conducted by CDC’s National Center for Health Statistics. This report presents 1992 national estimates of vaccination coverage for 2-year-old children and describes changes from 1991 to 1992.
