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 year-to-date (provisional data). In addition, the table compares provisional data with data for the previous year and highlights the number of reported cases among children aged <5 years, who are the primary focus of CII. Data in the table are reported through the National Electronic Telecommunications System for Surveillance (NETSS).
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 >=97% cases.
 & Invasive disease; H. influenzae serotype is not routinely reported to the National Notifiable
   Diseases Surveillance System. Of 55 cases among children aged <5 years, serotype was
   reported for 22 cases, and of those, 12 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.
** Two cases with onset in 1997 have been confirmed; two suspected cases are under
   investigation, of which one is in a child aged <5 years. One suspected case in a child aged
   <5 years with onset in 1998 is also under investigation.
