This report presents the main findings of the evaluation of Gavi supported measles supplementary immunisation activities in Nigeria. The evaluation addresses the effects of measles campaigns and their effect on the routine immunisation services. The Evaluation was conducted by KIT Royal Tropical Institute (KIT), Amsterdam in cooperation with the society for family Health (SFH), Nigeria.
Evaluation objectives
Measles is an important public health problem in Nigeria. Gavi has been supporting the measles vaccination in Nigeria for children between 9-59 month since 2013. Several campaigns have been conducted but Nigeria’s measles epidemiological profile indicates that there it continues to be a high risk for measles outbreaks.
The evaluation asses both the quality of the recurrent measles campaigns (2015/2016 and 2017/2018) and their effect on the immunisation system. And the extent to which campaigns integrated lessons learned from previous campaigns. The evaluation was conducted during the implementation of the 2017-2018 measles vaccination campaign (data collection between November 2017 and March 2018).
KIT focused the evaluation on three main areas of assessment:
- The quality of the recurrent measles campaigns
- The effect of the recurrent measles campaigns on the routine immunisation system
- The extent to which campaigns integrated lessons learned from previous campaigns into their respective design, planning, implementation and post campaign states in Nigeria.
Methods
To perform this assessment KIT and SFH implemented a mixed methods approach, using both quantitative and qualitative methods, including:
- A desk review of key documents focused on lessons learned from earlier campaigns in Nigeria
- Data collection on the results of the campaigns in terms of measles vaccination coverage and on the effects of the campaigns on children at risk of being zero dose children.
- Quality of the campaigns to explain the various success and challenges to reach the objectives of the campaign.
Findings and conclusions
- The evaluation validated the campaigns to be of a good quality based on their design according to international standards (WHO & Gavi)
- The quality of the campaigns benefitted as well from the integration of lessons learned from earlier measles (and other) vaccination campaigns
- Comparison of the 2016 and 2018 PMCCS results showed that improvements on vaccination cover has been made.
- The overall vaccination coverage increased by 3 percentage points and five states achieved 95% or higher MCV1 coverage
- Many efforts to “Reach all Targeted Children” during the campaigns were observed.
