Elimination of measles and of disparities in measles childhood vaccine coverage among racial and ethnic minority populations in the United States.

Abstract

The gap in measles vaccine coverage between white and nonwhite children was as large as 18% in 1970. During the measles epidemic of 1989-1991, attack rates among nonwhite children <5 years of age were 4- to 7-fold higher than rates among white children. Because of the epidemic and of the known disparity in vaccine coverage and risk of disease, a dual strategy to eliminate measles in the United States was implemented: universal interventions likely to reach the majority of children and targeted interventions more likely to reach nonwhite children. In 1992, the gap in coverage between white and nonwhite children was reduced to 6% (from 15% in 1985); the risk of disease among nonwhite children was narrowed to <or=4-fold the risk of white children. During the 1990s, further implementation of the dual strategy resulted in narrowing the gap in vaccine coverage to 2% and elimination of endemic disease in all racial and ethnic populations. This dual strategy deserves close scrutiny by health professionals and policy makers in devising programs to meet the Healthy People 2010 objectives for the elimination of other health disparities.
