Figure 4.4
The map shows provincial-level measles incidence and Supplementary Immunization Activities (SIA) between 2003 and 2011. Many SIAs have been conducted in western provinces during the past several years, but lack sustained impact, because of the inadequate level of follow-up routine vaccination. This is due to insufficient financial support and low operational capacity. Since 2008, a number of SIAs have taken place in eastern and western provinces, in response to a higher incidence of measles in these areas, largely linked to the inflow of migrant populations.

* National SIA was conducted in 2010. NoSIAs in 2011.
