In 1990 the Department of National Health and Population Development of South Africa launched a nationwide immunisation campaign targeted mainly at measles. In order to measure the effect of the campaign on vaccination coverage rates for children, pre- and post- campaign vaccination coverage surveys were undertaken using a modified Expanded Programme for Immunisation technique, stratified for race and urban/rural residence. The results in KwaZulu-Natal showed no significant increase in measles vaccination coverage for any race rates after the campaign (as documented by Road-to-Health cards). There was a decrease in coverage of the black population. However, when a history of measles vaccination was accepted, the results showed an increase in coverage. The results call into question the effectiveness of immunisation campaigns as a strategy for raising vaccination coverage levels, as well as their having a sustained impact on the incidence of measles. Alternative strategies, such as the strengthening and expansion of existing primary health care services, should be considered.
