Indicator name:
Neonates protected at birth against neonatal tetanus (%) (WUENIC)
Short name:
Neonates protected at birth against neonatal tetanus (%)
Data type:
Percent
Indicator Id:
98
Topic:
Health service coverage
Rationale:
Immunization is an essential component for reducing under-five mortality. Immunization coverage estimates are used to monitor coverage of immunization services and to guide disease eradication and elimination efforts. It is a good indicator of health system performance.
Definition:
The proportion of neonates in a given year that can be considered as having been protected against tetanus as a result of maternal immunization.
M&E Framework:
Outcome
Method of estimation:
PAB coverage is estimated using a mathematical model. PAB is the proportion of births in a given year that can be considered as having been protected against tetanus as a result of maternal immunization. In this model, annual cohorts of women are followed from infancy through their life. A proportion receive DTP in infancy (estimated based on the WHO-UNICEF estimates of DTP3 coverage). In addition some of these women also receive TT through routine services when they are pregnant and may also receive TT during Supplementary Immunization activities (SIAs) . The model also adjusts reported data, taking into account coverage patterns in other years, and/or results available through surveys. The duration of protection is then calculated, based on WHO estimates of the duration of protection by doses ever received. A further description of the model can be found in: Griffiths U., Wolfson L., Quddus A.,Younus M., Hafiz R.. Incremental cost-effectiveness of supplementary immunization activities to prevent neo-natal tetanus in Pakistan. Bulletin of the World Health Organization 2004; 82:643-651   Predominant type of statistics: predicted
Method of estimation of global and regional aggregates:
Global and regional coverage is a weighted sum of WHO/UNICEF estimates of national coverage by target population from the United Nations Population Division's World Population Prospects. The size of the target population is the national annual number of births.
