Impact of measles outbreak response vaccination campaign in Dar es Salaam, Tanzania.
We assessed the impact of a measles outbreak response vaccination campaign (ORV) in Dar es Salaam, Tanzania. Age-specific incidence rates were calculated before and after the ORV. Incidence rate ratios for the two time periods were compared and used to estimate expected cases and deaths prevented by ORV. The ratio of measles incidence rates in the age groups targeted and not targeted by ORV decreased from 5.8 prior to ORV to 1.8 (p<0.0001) after; 506 measles cases and 18 measles deaths were likely averted. These results support the need for revised recommendations concerning ORV in general settings in Africa.
