Objectives: Mass distribution of vitamin A supplementation (VAS) and measles vaccination has contributed to the reduction in child mortality in Sierra Leone from 267/1000 in 2005 to 118/1000 in 2010. In May 2012, the twice-yearly Maternal and Child Health Week (MCHW) integrated VAS and supplementary measles vaccination to reach all children 6-59 months in Sierra Leone. Following the MCHW, a Post Event Coverage Survey (PECS) was conducted to validate coverage and assess Adverse Events Following Immunization (AEFI). Methods: Using WHO EPI sampling methodology, 30 clusters were randomly selected with fourteen caregivers of children 6-59 months interviewed per cluster for precision of ±5%. In addition, one health worker was interviewed per cluster with all responses collected via mobile phones using EpiSurveyor. Results: Overall coverage confirmed by campaign card for VAS and measles vaccination was 91.9% and 91.6%, respectively, with no significant differences by age group, sex, religion or occupation. Major reasons given for not receiving VAS and measles vaccination were not knowing about the MCHW or being out of the area. No serious AEFI’s were reported during the MCHW or PECs. Significantly more mild AEFIs (fever, pain at injection site) were reported via PECS (29.1%) than during the MCHW (0.01%) (p<0.0001). Conclusions: The MCHW reached >90% of children in Sierra Leone with equitable coverage. Increased reporting of mild AEFI’s during the PECs may be attributed to delayed onset after measles vaccination and/or direct enquiry from enumerators. While all reported AEFIs were mild, strengthened reporting of AEFIs during/after vaccination campaigns is recommended.
