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

In 1993, the Childhood Immunization Initiative (CII) was instituted to increase vaccination coverage among 2-year-old children to at least 90% by 1996 for four of the five vaccines routinely recommended for children* and to at least 70% for three doses of hepatitis B vaccine (1). To monitor progress toward these goals, national estimates of vaccination coverage are needed. This report presents national estimates of vaccination coverage among 2-year-old children derived from provisional data from the National Health Interview Survey (NHIS) for the third quarter of 1993 and describes the trend in vaccination coverage since 1992, the baseline year.
