The Healthy People 2010 objective for the complete series of routinely
recommended childhood vaccinations is immunization of at least 90
percent of 19- to 35-month-olds with the full series of vaccines.
Data released from CDC’s 2002-2003 National Immunization Survey
revealed that 77.9 percent of children ages 19-35 months have received
the recommended 4:3:1:3:3 series of vaccines (4 DTaP, 3 polio, 1
MCV, 3 Hib, 3 hepatitis B). In the past 5 years, the greatest increases
in vaccination rates have occurred with the hepatitis B vaccine
and the varicella (chicken pox) vaccine, which was added to the
schedule in 1996. Since 1997, the vaccination rate for hepatitis
B has increased by almost 9 percent to 91.9 percent in 2002. The
varicella vaccination rate rose to 82.5 percent, which represents
a more than two-fold increase since 1997. Despite this progress,
approximately 900,000 children under 2 years of age have not received
the recommended immunization series to be fully protected.1
Among children aged 19-35 months, non-Hispanic Black children have
the lowest immunization rates of any racial/ethnic group and they
are consistently below the national average for each of the major
In April 2004, the CDC published an updated immunization schedule
(see facing page). The 2004 schedule continues to encourage the
routine use of hepatitis B vaccine for all infants before hospital
discharge and also recommends the expansion of routine influenza
immunization to include all children 6 to 23 months of age.
