The Centers for Disease Control and Prevention (CDC) reported increases from 2003 to 2004 in vaccination coverage among children 19 to 35 months of age for the combined vaccine series 4:3:1, 4:3:1:3:3, and 4:3:1:3:3:1 (see box) as well as for the recently implemented varicella and pneumococcal conjugate vaccines (National, State, and Urban Area Vaccination Coverage Among Children Aged 19–35 Months—United States, 2004 MMWR 2005;54:717–21). For the first time, coverage for the 4:3:1:3:3 series exceeded the Healthy People 2010 goal of 80 percent, although it varied substantially among states and urban areas, ranging from 68 percent in Nevada to 89 percent in Massachusetts.
The report states that coverage levels are notable given the supply shortage of several vaccines between 2001 and 2004. Recurrence of shortages is likely, therefore strategies for managing supply and continued monitoring are needed.
