Progress Toward Measles Control - African Region, 2001-2008 by ProQuest


In 2001, the countries of the World Health Organization African Region became part of a global initiative with a goal of reducing the number of measles deaths by 50% by 2005, compared with 1999. Here, a report that summarizes the progress made during 2001-2008 toward improving measles control in AFR is presented. Supplemental immunization activities provide a second opportunity for measles immunization to all children, including those not vaccinated; approximately 15% of children vaccinated with a single dose at age 9 months will not develop immunity to measles. A CDC editorial note is also presented.
