“…Nevertheless, one LGA failed to achieve the maximum target in November and the cause of this lower coverage should be identified. Furthermore, the proportion of missed children (outside house monitoring) rose to 21% during November SIA-this finding differed from the decreasing trend reported by Okeibunor et al [14] The cause of this increase in the proportion of missed children should be investigated and corrective actions should be taken to improve this indicator in future SIAs.…”

“…One explanation for the dramatically attenuated association in AFR is lower campaign coverage. However, monitoring data suggests that polio campaigns vaccinate the vast majority of eligible children in a given area [21]. Therefore, a more plausible explanation is a major difference in the accuracy of reported doses.…”

“…The drop of only 1% from the previous campaign is also relatively small compared to the proportion of the population that belongs to the Catholic Church. As per the World Health Organization standards, a vaccination campaign is regarded as successful if less than 10% of the children are missed during the vaccination [32]. Therefore the coverage of 93% that was achieved could be regarded as largely successful even if 4 (12.5%) counties had a coverage of less than 90%.…”

“…For example, of all the polio vaccination campaigns that were done in the African region in 2010, 2011 and 2012, only 7.94%, 6.86% and 5.95% of the children were missed, respectively. During the same years, the proportion of children that were missed in the South and East Africa sub region were 12.4%, 11.26%, 13.69%, respectively [32]. …”

IntroductionPolio eradication is now feasible after removal of Nigeria from the list of endemic countries and global reduction of cases of wild polio virus in 2015 by more than 80%. However, all countries must remain focused to achieve eradication. In August 2015, the Catholic bishops in Kenya called for boycott of a polio vaccination campaign citing safety concerns with the polio vaccine. We conducted a survey to establish if the coverage was affected by the boycott.MethodsA cross sectional survey was conducted in all the 32 counties that participated in the campaign. A total of 90,157 children and 37,732 parents/guardians were sampled to determine the vaccination coverage and reasons for missed vaccination.ResultsThe national vaccination coverage was 93% compared to 94% in the November 2014 campaign. The proportion of parents/guardians that belonged to Catholic Church was 31% compared to 7% of the children who were missed. Reasons for missed vaccination included house not being visited (44%), children not being at home at time of visit (38%), refusal by parents (12%), children being as leep (1%), and various other reasons (5%). Compared to the November 2014 campaign, the proportion of children who were not vaccinated due to parent's refusal significantly increased from 6% to 12% in August 2015.ConclusionThe call for boycott did not affect the campaign significantly. However, if the call for boycott is repeated in future it could have some significant negative implication to polio eradication. It is therefore important to ensure that any vaccine safety issues are addressed accordingly.
