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 all 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 <5 years, who are the primary focus of CII. Data in the table are reported through the National Electronic Telecommunications System for Surveillance (NETSS). Table_1 Note:

* Data for 1995 and 1996 are provisional.
+ For 1995 and 1996, age data were available for >=93% cases, except for 1996 age data for
measles, which were available for 81% of cases.
& Invasive disease; H. influenzae serotype is not routinely reported to the National Notifiable
Diseases Surveillance System. Of 142 cases among children aged <5 years, serotype was
reported for 32 cases, and of those, nine 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. Two cases with onset
in 1995 have been confirmed; these cases were vaccine-associated. An additional six
suspected cases are under investigation for 1995. Five cases with onset in 1994 were
confirmed; all were vaccine-associated.
