Figure 2.

Estimated number of malaria vaccine doses delivered per year over a 10-year period. Numbers of doses delivered are based upon reports of the use of Hib vaccine to WHO between 2001 and 2010 from 40 countries in sub-Saharan African with significant malaria burden. The number of countries that began implementation each year is indicated below the x axis (note that there is a delay between the time each country begins implementation and reaches peak coverage).
