Abstract


Background: Yogyakarta Province is the only province in
Indonesia that piloted IPV immunization since September 2007.
Therefore, it is essential to evaluate the implementation of this
new program. This study was aimed to determine the coverage
and timeliness of the IPV immunization after 2.5 years of
its introduction.
Method: A cross sectional study was carried out using the
WHO standard cluster sampling to estimate the immunization
coverage in urban Yogyakarta City and the remaining rural
districts in Yogyakarta Province. The subjects consisted of
children aged 12-23 months old and their parents. A questionnaire
was used to acquire information from parents/caregivers
on demographic, socioeconomic, and IPV immunization status,
dates, location, and access of immunization. Epi InfoTM 2003
software was used for data entry and analysis.
Result: Overall, 426 children were involved in the study (215
in urban and 211 in rural areas). The coverage for IPV1 through
IPV4 was 100%, 99.8%, 99.3%, and 96.7%, respectively. There
was no difference in coverage by urban/rural location, parents’
education level, number of siblings, and distance to health
service. The coverage is very similar to that of survey in 2004
when this province still used oral polio vaccine. The mean
ages of IPV administration were 2.3, 3.5, 4.8, and 9.4 and no
significant difference among urban and rural areas was found.
More than 95% children received IPV immunization at appropriate
age.
Conclusion: The IPV pilot project in Yogyakarta Province has
been implemented well with high coverage and appropriate
timeliness.
