Update: childhood vaccine-preventable diseases--United States, 1994.

In 1993, the Childhood Immunization Initiative (CII) established disease elimination goals for six childhood vaccine-preventable diseases. Specific goals for 1996 include elimination of indigenous transmission of measles, rubella (and congenital rubella syndrome [CRS]), poliomyelitis (polio) caused by wild poliovirus, and diphtheria in all age groups; elimination of tetanus in children aged < 15 years; and elimination of invasive disease due to Haemophilus influenzae type b (Hib) in children aged < 5 years. This report summarizes progress toward reaching these goals during January-August 1994, compares these findings with those from the same period during 1993, and provides information about mumps and pertussis--diseases for which reduction goals will be established.
