Vaccination Coverage Survey in Sierra Leone

Share

In May 2012, Sierra Leone experienced the the twice-yearly Maternal and Child Health Week (MCHW) integrated vitamin A supplementation and supplementary measles vaccination to reach all children 6–59 months (similar to the Malezi Bora campaigns in Kenya). After the activity, a vaccination coverage survey was undertaken to determine coverage and assess adverse events.

Magpi was used for the field survey data collection over a 5 day period, with 57 surveyors using mobile phones and 13 supervisors trained on support and quality assurance of the these surveyors.

“MCHW successfully provided 1.2 million measles vaccines and vitamin A supplements to children, reaching over 90% of eligible children.”
