Abbreviated Name:
DPT3/Pentavalent Immunization coverage rate coverage among children under 1 year of age (%)
Indicator Name:
DPT3/Pentavalent Immunization coverage rate coverage among children under 1 year of age (%)
Domain:
Health System Response/ Service coverage
Related Terms:
Immunization Diphtheria, pertussis, tetanus
Definition:
The percentage of one-year-olds who have received three doses of the combined diphtheria, tetanus toxoid and pertussis vaccine in a given year.
Measurment Method:
Service/facility reporting system ("administrative data"): Reports of vaccinations performed by service providers (e.g. district health centres, vaccination teams, physicians) are used for estimates based on service/facility records. The estimate of immunization coverage is derived by dividing the total number of vaccinations given by the number of children in the target population, often based on census projections. Household surveys: Survey items correspond to children’s history in coverage surveys. The principle types of surveys are the Expanded Programme on Immunization (EPI) 30-cluster survey, the UNICEF Multiple Indicator Cluster Survey (MICS), and the Demographic and Health Survey (DHS). The indicator is estimated as the percentage of children ages 12–23 months who received three doses of the combined diphtheria, tetanus toxoid and pertussis vaccine time before the survey.
Numerator:
For vaccines in the infant immunization schedule, this would be the number of children aged 12–23 months who have received the specified vaccinations before their first birthday.
Denominator
The total number of individuals in the target group for each vaccine. For vaccines in the infant immunization schedule, this would be the total number of infants surviving to age one.
Estimation method:
WHO and UNICEF jointly developed a methodology to estimate national immunization coverage from selected vaccines in 2000. The methodology has been refined and reviewed by expert committees over time. The methodology was published and reference is available under web site https://www.who.int/immunization/monitoring_surveillance/routine/coverage/en/index4.html. Estimates time series for WHO recommended vaccines produced and published annually since 2001. The methodology uses data reported by national authorities from countries administrative systems as well as data from immunization or multi indicator household surveys
Disaggregation:
Age, place of residence, sex, socioeconomic status
Primary data sources:
National Health Information Systems or National Immunization systems National immunization registries
Alternate data sources:
High quality household surveys with immunization module (e.g. DHS, MICS, national in-country surveys)
Measurment frequency:
Quarterly, Annual
