Quarterly Immunization Table

To track progress toward achieving the goals of the Childhood Immunization Initiative (CII), CDC publishes quarterly a tabular summary Table_1 of the number of cases of nationally notifiable diseases preventable by routine childhood vaccination reported during the previous quarter and the year to date (provisional data). In addition, the table compares provisional data with provisional data for the previous year and highlights the number of reported cases among children aged less than 5 years, who are the primary focus of CII. Data in the table are reported through the National Electronic Telecommunications System for Surveillance.
Note: To print large tables and graphs users may have to change their printer settings to landscape and use a small font size.

 * Data for 1997 and 1998 are provisional.
 + For 1997 and 1998, age data were available for >=96% of cases.
 & Invasive disease; H. influenzae serotype is not routinely reported to the National Notifiable
   Diseases Surveillance System. Of 132 cases among children aged <5 years, serotype was
   reported for 74 cases, and of those, 32 were type b, the only serotype of H. influenzae
   preventable by vaccination.
 @ Because most hepatitis B virus infections among infants and children aged <5 years are
   asymptomatic (although likely to become chronic), acute disease surveillance does not
   reflect the incidence of this problem in this age group or the effectiveness of hepatitis B vac-
   cination in infants.
** One case with onset in 1998 and three cases with onset in 1997 have been confirmed. All
   were associated with administration of oral poliovirus vaccine. One suspected case with
   onset in 1997 remains under investigation.
