Monthly Immunization Table

To track progress toward achieving the goals of the Childhood Immunization Initiative (CII), CDC publishes monthly a tabular summary (Table_1) of the number of cases of all diseases preventable by routine childhood vaccination reported during the previous month and year-to-date (provisional data). In addition, the table compares provisional data with final 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 (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 1994 are final, and 1995 are provisional.
+  For 1994 and 1995, age data were available for >=93% cases.
&  Invasive disease; H. influenzae serotype is not routinely reported to the National
   Notifiable Diseases Surveillance System. Of 253 cases among children aged <5 years,
   serotype was reported for 61 cases, and of those, 37 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 vaccination in infants.
** One case with onset in 1994 has been confirmed; this case was vaccine-associated. An
   additional six suspected cases are under investigation. In 1993, three of 10 suspected
   cases were confirmed; two of the confirmed cases were vaccine-associated, and one was
   imported. The imported case occurred in a 2-year-old Nigerian child brought to the United
   States for care of his paralytic illness; no poliovirus was isolated from the child.
