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).

* 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 271 cases among children aged <5 years, serotype was
reported for 63 cases, and of those, 38 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 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.
