To track progress toward achieving the goals of the Childhood
Immunization Initiative (CII), CDC publishes monthly a tabular
summary of the number of cases of all diseases preventable by
routine childhood vaccination reported during the previous month
and year-to-date (provisional data) (Table_1). 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 or equal to 5 years, who are the primary focus of CII. Data in
the table are derived from CDC's National Notifiable Diseases
Surveillance System. Table_1 Note:

* Data for 1993 are final and for 1994, provisional.
+ For 1993 and 1994, age data were available for 85% or more cases, except for 1993 CRS,
which were available for 50% of cases, and 1994 pertussis and tetanus, which were available
for 84% and 67% of cases, respectively.
& Invasive disease; H. influenzae serotype is not routinely reported to the National Notifiable
Diseases Surveillance System.
@ 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.
** No cases of suspected poliomyelitis have been reported in 1994; three cases of suspected
poliomyelitis have been reported in 1993; four of the five suspected cases with onset in
1992 were confirmed; the confirmed cases were vaccine associated.
