Vaccination coverage of 2-year-old children--United States, 1993.

The primary goal of the Childhood Immunization Initiative (CII) is to increase, by 1996, vaccination levels for 2-year-old children to at least 90% for the most critical doses in the vaccination series (i.e., one dose of measles-mumps-rubella vaccine [MMR] and at least three doses each of diphtheria and tetanus toxoids and pertussis vaccine [DTP], oral poliovirus vaccine, and Haemophilus influenzae type b vaccine [Hib]) and to at least 70% for three or more doses of hepatitis B (Hep B) vaccine (1). This report presents estimates, based on the National Health Interview Survey (NHIS), of the annual national vaccination coverage levels for children aged 19-35 months (median: 27 months) for 1993, compares estimates for 1993 with those for 1992, and compares estimates for the first 6 months of 1993 with third and fourth quarter 1993 estimates.
