Measles vaccination in Africa: By how much could routine coverage be improved?

Assuming that the level of Bacille Calmette Guerin (BCG) coverage gives a measure of access to immunisation services, it is possible to derive what fraction of infants are not immunised against measles due to under-utilisation of existing services (rather than unavailability of services). According to the most recent official statistics, the overall coverage for measles vaccine is 53% in Africa (10% lower than for BCG). This difference amounts to 3 million African children who will not be vaccinated against measles this year even though they probably have access to immunisation services. © 2001 Elsevier Science Ltd.
