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 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 1995 are final and for 1996 are provisional.
+ For 1995 and 1996, age data were available for >= 93% of cases, except for 1996 age data for
measles, which were available for 88% of cases.
& Invasive disease; H. influenzae serotype is not routinely reported to the National Notifiable
Diseases Surveillance System. Of 190 cases among children aged <5 years, serotype was
reported for 42 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.
** Three suspected cases with onset in 1996 have been reported to date. Four cases with onset
in 1995 have been confirmed; these cases were vaccine-associated. An additional six
suspected cases are under investigation. Eight cases with onset in 1994 were confirmed;
all were vaccine-associated.
