The study population was extracted from the Nouna HDSS cohort. Data from four rounds of interviews conducted between November 2012 and June 2014 were considered. This study included 4016 children aged 12 to 23 months. We assessed the effects of several risk factors including sex, factors reflecting access to health care and maternal factors. The risk factor analysis was carried out using binomial regression in univariate and multivariate regression models. The full vaccination coverage increased significantly over time (72% in 2012; 79% in 2013 and 81% in 2014, p=0.01), and the coverage was significantly lower in urban compared with rural areas (relative risk (RR) of being fully vaccinated: 0.84 (0.80-0.89)). There were no differences in vaccination coverage between boys and girls (RR: 0.99 (0.96-1.03)) or by maternal factors. The study documented a further improvement of full vaccination coverage in Burkina Faso.
