Executive summary
Introduction
The National Post Measles Campaign Coverage Survey (PMCCS) was conducted following measles campaign targeting children aged 9 and 59 months in conducted in Nigeria between November 2017 and March 2018 in Nigeria. The survey was commissioned by the National Primary Healthcare Development Agency (NPHCDA) and implemented by the National Bureau of Statistics. Technical assistance was provided by the World Health Organization while funding was provided by PMCCS provides information on the children receiving measles vaccination during the measles campaign. PMCCS was carried out from January to April 2018 and covered 6819 households with 10151 children aged between 9 and 59 months. The population sampled for the PMCCS is representative of children aged 9 to 59 months nationally and in all 36 states and FCT- Abuja.
Measles vaccination coverage
Eighty eight percent of all children who were eligible for measles vaccination during the campaign were vaccinated. Five states (Anambra, Ekiti, FCT-Abuja, Jigawa and Plateau) achieved an estimated coverage of 95 percent and above.
Proportion of children who received measles vaccination for the first time during the campaign
National close to 10 million children making 35 percent of all children aged between 9 and 59 months received measles vaccination for the first time ever during the measles campaign. As many as 59 percent of children aged 9 to 59 months living in Abuja, 67 percent of children aged 9 to 59 months living in Zamfara and 78 percent of children aged 9 to 59 months living in Katsina state.
Children with SIA cards
Only 59 percent of children who received measles vaccination during the campaign reported receiving a vaccination card during the campaign. The proportion of children who received a vaccination card was as low as 31 percent in Adamawa State and 35 percent in Kogi State.
Sources of information about the campaign
Nationally 3.9 percent of the respondents interviewed were not informed about the measles campaign. The proportion of respondents who were not informed ranged from .03 percent in Jigawa state to 11.5 % in Bauchi state. All respondents in Abuja knew about the measles campaign. Majority of the respondents were informed about the measles campaign through radio, mobilisers (criers), community health workers and village chiefs.
Reason for non-vaccination
Majority of the children were not vaccinated as a result of not being at home in the period of the vaccination campaign and also because the parents or primary caregivers were not aware of the vaccination campaign.
Information on previous vaccination status
Slightly over a half of eligible children had received measles vaccination before the campaign but only 16 percent of all eligible children had a card showing when the vaccination was given.
The primary objective of the survey was to determine the coverage of measles vaccination in all states, the Federal Capital Territory, Abuja and nationally. Secondary objectives of the survey were:
- To stratify SIA coverage estimates by age group (9-11 months, 12-59 months)
- To stratify SIA coverage estimates by sex
- To identify key communication channels that were effectively used for the campaign
- To determine reasons for non-vaccination of eligible children during the campaign
- To determine occurrence of adverse events following immunization (AEFI) during the campaign
- To determine the proportion of children receiving the first dose of measles vaccine during the campaign (i.e., previously unvaccinated)

Sampling
PMCCS was based on the National Population Commission (NPopC) master sampling frame based on the 2006 Nigeria Housing and Population Census. The sampling frame developed under the National Integrated Survey of Households (NISH2). Areas of the country that are inaccessible due to security reasons were excluded from the sampling frame including specific Local Government Areas (LGAs) in Borno and Adamawa states. Interpretation of results from these areas should therefore be conducted in light of these exclusions.
A stratified two stage - cluster sampling design was chosen for the 2017/18 PMCCS. Reporting strata were 36 state and FCT- Abuja.
The first stage selection involved the selection of EAs in each state and the FCT (Abuja) from the master sampling frame. A total of 30 EAs were selected from the sampling frame and with the selection probability of each EA was recorded for incorporation into household weights.
Following first stage sampling, household listing was conducted in the selected EAs to map all structures and boundaries and also identify households with children aged between 9 and 59 months eligible for second stage selection. Household listing was conducted between the 2nd and 9th of December 2017.
Second stage selection of households to be interviewed was conducted by the National Bureau of Statistics (NBS) using simple random sampling without replacement from the list of households with eligible children aged 9 to 59 months. Seven (7) households with eligible children were randomly selected from each of the 30 enumeration areas in every state.
No Deviation
Nationally, the household response rate was 96.2 percent. The household response rate was generally higher in rural areas compared to urban areas with the response rate being 97.4 percent and 92.6 percent respectively. Notably, the household response rates in Lagos, Ebonyi, Oyo, Abuja and Abia were below 90 percent. Despite a planned sample size of 7 eligible households per EA, this planned sample was only achieved in 8 states. In a majority of the states, there were less than 7 households with eligible children available for selection to the survey and were all selected in the EA.
Design weights were computed as the product of inverse probabilities of selection in the first and second stage. Next, the design weight was adjusted for household non-response and child non-response to get the sampling weights for households and for children, respectively. Non-response was adjusted at the sampling stratum level. After adjusting for non-response, the sampling weights were normalized and post stratified to get the final standard weights that appear in the data files. Post-stratification was conducted by multiplying the normalised weights with the estimated proportion of children aged 9 to 59 months in each stratum. The estimated number of children in each stratum was obtained from recently concluded microplanning activity.
Bivariate analysis of post measles campaign vaccination coverage, reasons for non-vaccination, AEFI and routine immunisation measles vaccination coverage were presented by residence, gender and zones. Wilson's 95% confidence intervals and upper and lower confidence bounds have been computed throughout the report.
Survey instrument
The questionnaire for the Post Measles Supplementary Immunization Activity Survey consisted of the following:
-Household Information Panel (Household rosters)
-Individual questionnaire- This questionnaire is to be administered to all mothers or caregivers who care for a child that lives with them and is within the age of 9 months - 59 months (5 years)
Data cleaning and analysis was conducted using the supplementary immunisation activity (SIA) module of Vaccination Coverage Quality Indicators (VCQI) software running on Stata version 14 (StataCorp. 2015. Stata Statistical Software: Release 14. College Station, TX: StataCorp LP.). All results presented in the report are based on the weighted data to account for the survey sampling design and survey nonresponse

There were three levels of quality assurance; Survey teams lead by the supervisors were responsible for quality of data collected. Data were collected on CAPI tablets with inbuilt range checks. Once an enumerator had finished data collection data were transferred to the supervisors CAPI tablet and reviewed the quality and completeness of the data before they were synchronized with the server. NBS state and zonal officers also ensured that the survey was conducted as per the survey guidelines and ensure that logistical support for the teams.
Monitoring by teams comprising of NPHCDA and NBS headquarters and state offices formed the second layer of quality assurance by conducting observations of interviews using checklists.
The third level of monitoring was conducted by monitoring data synchronized to the server and inconsistencies picked up were flagged up to the team supervisor who corrected them before teams left a specific EA.
Interviewers were selected from the states they were deployed in to ensure that the interviewers could speak languages in the state they were assigned to and were conversant with the local culture. Two levels of training were conducted for household listing and mapping. The first stage of training was a training of trainers conducted in Abuja while the second level of training was conducted in every state. The first level training consisted of resource persons and participants from NBS, NPHCDA, WHO, UNICEF and other relevant technical partners while the second level training targeted field workers who were to conduct mapping and listing activities in selected EAs.
A total of 600 personnel comprising of field team supervisors and enumerators were trained of whom 555 were selected to form the data collection teams. Training focused on the survey guidelines, identification of sampled enumeration areas and eligible households, determination of whether an eligible child had been vaccinated, ethics and informed consent, electronic data capture and transmission, and conducting quality control checks. In addition, supervisors were trained on managing survey logistics and on documenting and reporting survey progress. A post-training test was conducted to ensure that only those participants who were conversant with conducting the survey were included into the survey team.

Survey implementation in Sokoto was conducted with implementation in the North East zone whereas Sokoto geographically belongs to the North West zone while implementation in Kogi and Kwara was conducted with states in South West zone although Kogo and Kwara belong to North Central zone. NW = North West, NE = North East, NC = North Central, SS = South-South, SE = South East, SW = South West
Data collection was conducted by 5 teams in every state with each team comprising of a supervisor and two enumerators. Each team canvased on average 6 enumeration areas in 14 days.
Data processing
Data collection was using Census and Survey Program (CSPro) software running on android computers. Range checks and skip patterns were predefined in the data entry program to ensure that only all valid responses were collected and there were responses to all applicable questions ensuring enhanced data quality and completeness of collected data. On completion of the household roster, only age-eligible respondents were presented to the interviewer for interviewing and information had to be collected on all selected respondents before a household completion status was generated by the CAPI software.
Data appraisal
Assuming an expected coverage of 90%, half-width confidence interval around state-level estimates of 8% (i.e., 90% +/- 8% coverage estimate) with an alpha level (type I error) of 5%, the effective sample size (i.e., sample size per stratum under a simple random sampling assumption) was n = 101. This level of precision allowed for estimation of coverage with acceptable precision at state, zonal and national levels1.
Series of tables and graphs were generated.
