84; 95% CI 0.72–0.99; p = 0.032) ( Table 3). Children with mothers aged 25–34 and 35–44 years were more likely to be vaccinated than children with mothers <25 years of age (aOR = 1.36; 95% CI 1.15–1.62; p < 0.001; and aOR = 1.35; 95% CI 1.10–1.64; p = 0.003, respectively). Children aged 2–5 years and >5 years of age were more likely to be vaccinated compared with those below

two years of age (aOR = 1.38; 95% CI 1.20–1.59; p < 0.001; and aOR = 1.41; 95% CI 1.23–1.63; p < 0.001, respectively). Finally, children that had a sibling hospitalized within one year prior to vaccine campaign were more likely to be vaccinated than children from households with no hospitalizations reported within one year prior to the campaign (aOR = 1.73; 95% CI 1.40–2.14; p < 0.001) ( Table 3). Influenza is a vaccine-preventable cause of medically attended illness, hospitalizations MAPK inhibitor and death each year in Kenya [10]. Despite the free distribution of influenza vaccine to children,

we observed a vaccine uptake of 37% for fully vaccinated children. While this compares favorably to the 33% uptake of seasonal vaccine observed in the United States during the 2004–2005 influenza season when vaccine was first recommended for young children Alectinib supplier [27], much room for improvement SB-3CT remains. While economic considerations are critical to future vaccine campaigns in Africa, behavioral determinants for seeking immunization are

also among the myriad challenges to improving influenza immunization rates in Africa. These factors are therefore important to consider in the implementation of future influenza vaccines campaigns. Multiple factors influence healthcare utilization at clinics, including cost, distance, quality of care, and severity of illness [28], [29], [30] and [31]. In the HDSS in western Kenya, many ill persons do not utilize free high-quality referral clinics; in 2009 only 30–40% of ill participants sought care at any clinic and only a half of those went to designated PBIDS referral clinics [22]. Accessibility to vaccination services in terms of walking time to the nearest place of vaccination, the child’s age, age of the mother, and the mother’s education have been cited as some of the determinants of vaccination in children in Africa [18]. Distance to the nearest vaccination facility, the child’s age and age of the mother clearly also played an important role in the use of fixed vaccination sites in this Kenyan context. In this study, as well as previous studies in developing countries [32] and [33], greater distance to primary health care facilities was negatively associated with vaccine uptake.
