Applying an equity lens in the Decade of Vaccines.

Addressing inequities in immunisation must be the main priority for the Decade of Vaccines. Children who remain unreached are those who need vaccination - and other health services - most. Reaching these children and other underserved target groups will require a reorientation of current approaches and resource allocation.

Global Immunization Vision and Strategy (GIVS): a mid-term analysis of progress in 50 countries.

Within the overall framework set out in the Global Immunization Vision and Strategy (GIVS) for the period 2006-2015, over 70 countries had developed comprehensive Multi-Year Plans (cMYPs) by 2008, outlining their plans for implementing the GIVS strategies and for attaining the GIVS Goals at the midpoint in 2010 or earlier. These goals are to: (1) reach ≥90% and ≥80% vaccination coverage at national and district level, respectively; and (2) reduce measles-related mortality by 90% compared with the 2000 level. Fifty cMYPs were analysed along the four strategic areas of the GIVS: (1) protecting more people in a changing world; (2) introducing new vaccines and technologies; (3) integrating immunization, other health interventions and surveillance in the health system context; and (4) immunizing in the context of global interdependence.

Economic analysis of the 1996-1997 mass measles immunization campaigns in South Africa.

To evaluate economic implications of conducting a "catch-up" measles vaccination campaign, we conducted an economic analysis of the 1996-1997 measles immunization campaign in two provinces of South Africa comparing the baseline two-dose routine immunization program to the combined vaccination strategy (routine two-dose immunization program, plus the 1996-1997 campaign). The study findings indicate that the 1996-1997 mass measles immunization campaign was cost-effective in both study provinces, and cost-saving in the province with higher pre-campaign disease incidence and lower routine vaccination coverage. An early investment in effective vaccination strategies that rapidly reduce disease burden apparently results in better returns, both epidemiologically and economically.

Molecular epidemiology of measles virus in Kenya.

Measles causes significant morbidity and mortality globally. Many countries have embarked on immunization programs to control and prevent measles outbreaks and eventually to eliminate endemic measles. Kenya is currently in the outbreak control and prevention stage for measles.

Impact of alternative approaches to accelerated measles control: experience in the African region, 1996-2002.

From 1996 to 2000, several African countries accelerated measles control by providing a second opportunity for measles vaccine through supplemental campaigns. Fifteen countries completed campaigns in children aged 9 months to 14 years. Seven countries completed campaigns in children aged 9-59 months.

Impact of the 1996-1997 supplementary measles vaccination campaigns in South Africa.

Background: In South Africa, as part of an effort to eliminate indigenous measles by 2002, vaccination campaigns were conducted in 1996-1997 targeting all children aged 9 months to 14 years; coverage was estimated at 85%. The impact of the campaigns on measles disease burden was evaluated in 1999.

Methods: We analysed routine measles surveillance data and undertook a retrospective review of hospital registers in two of South Africa's nine provinces.

First 5 years of measles elimination in southern Africa: 1996-2000.

Background: Measles is the leading cause of vaccine-preventable death in Africa. Regional measles elimination is considered feasible using current vaccines and a series of WHO-recommended strategies. We aimed to interrupt transmission of measles, and to use case-based surveillance to show the effect of such interruption.
