Monthly Immunization Table

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 <5 years, who are the primary focus of CII. Data in the table are reported through the National Electronic Telecommunications System for Surveil-lance (NETSS).

* Data for 1994 and 1995 are provisional.
+ For 1994 and 1995, age data were available for >=93% cases.
& Invasive disease; H. influenzae serotype is not routinely reported to the National Notifiable
Diseases Surveillance System. Of 209 cases among children aged <5 years, serotype was
reported for 54 cases, and of those, 32 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 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.
