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.

* Data for 1994 and 1995 are provisional.
+ For 1994 and 1995, age data were available for >=93% of cases.
& Invasive disease; H. influenzae serotype is not routinely reported to the National
Notifiable Diseases Surveillance System. Of 177 cases among children aged <5 years,
serotype was reported for 47 cases, and of those, 27 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 July 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 of 1993 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.
