The number of vaccines available to low-income countries has increased dramatically over the last decade. Overall infant immunization coverage in the WHO African region has stagnated in the past few years while countries' ability to maintain high immunization coverage rates following introduction of new vaccines has been uneven. This case study examines post-introduction coverage among African ...

This paper examines inequalities in the use of, and access to, vaccination service in Bangladesh by analyzing national and small area-based datasets. The analysis showed that female children had a lower immunization coverage than male children--the difference persists for all antigens and widens against girls for higher doses. The immunization coverage was higher for children whose mothers were...

In 1993 a large outbreak of paralytic poliomyelitis occurred in Sudan as a result of an accumulation of large numbers of susceptible children that was accelerated by faltering immunization services. The extent of the outbreak led to the rapid rehabilitation of Sudan's Expanded Programme on Immunization (EPI); the government began financing vaccine purchase, operational aspects of EPI were decen...

evidence provided from studies in iran points to a possible bias in application of the standard epi cluster sampling procedure, when carried out in populations with highly variant birth rates, tends to over-represent the low birth rate, i.e. higher socio-economic, strata, and if the entity under study shows significant socio-economic gradient, then the estimates arrived at by this method might ...

BACKGROUND Guangdong province attracted more than 31 million migrants in 2010. But few studies were performed to estimate the complete and age-appropriate immunization coverage and determine risk factors of migrant children. METHODS 1610 migrant children aged 12-59 months from 70 villages were interviewed in Guangdong. Demographic characteristics, primary caregiver's knowledge and attitude to...

Diphtheria remains endemic in developing countries, but there are limited published data on the subject. Thailand's diphtheria surveillance data are relatively complete and may give a fuller picture of the situation in similar countries. After routine immunization began in 1977, the incidence of reported diphtheria decreased by >98% to <0.1 case per 100,000 persons annually in the 1990s. Despit...

OBJECTIVE A primary objective of the Healthy People 2010 initiatives is to increase on-time immunization rates during the first 2 years of life and to decrease racial disparities in coverage. The objective of this study was to determine on-time immunization coverage rates among infants and toddlers stratified by race/ethnicity in a large metropolitan center. METHODS A retrospective cohort stu...
