The Gambia - Immunization, HepB3 (% of one-year-old children)

The value for Immunization, HepB3 (% of one-year-old children) in The Gambia was 88.00 as of 2019. As the graph below shows, over the past 28 years this indicator reached a maximum value of 98.00 in 2012 and a minimum value of 56.00 in 1993.

Limitations and Exceptions: In many developing countries a lack of precise information on the size of the cohort of one-year-old children makes immunization coverage difficult to estimate from program statistics.

Statistical Concept and Methodology: Governments in developing countries usually finance immunization against measles and diphtheria, pertussis (whooping cough), and tetanus (DTP) as part of the basic public health package. The data shown here are based on an assessment of national immunization coverage rates by the WHO and UNICEF. The assessment considered both administrative data from service providers and household survey data on children's immunization histories. Based on the data available, consideration of potential biases, and contributions of local experts, the most likely true level of immunization coverage was determined for each year.
