Nigeria is estimated to have the largest number of children worldwide, living with chronic hepatitis B virus (HBV) infection, the leading cause of liver cancer. Up to 90% of children infected at birth develop chronic HBV infection. A birth dose of the hepatitis B vaccine (HepB-BD) followed by at least two additional vaccine doses is recommended for prevention. This study assessed barriers and facilitators of HepB-BD administration and uptake, using structured interviews with healthcare providers and pregnant women in Adamawa and Enugu States, Nigeria. The Consolidated Framework for Implementation Sciences Research (CFIR) guided data collection and analysis. We interviewed 87 key informants (40 healthcare providers and 47 pregnant women) and created a codebook for data analysis. Codes were developed by reviewing the literature and reading a subsample of queries line-by-line. The overarching themes identified as barriers among healthcare providers were: the lack of hepatitis B knowledge, limited availability of HepB-BD to vaccination days only, misconceptions about HepB-BD vaccination, challenges in health facility staffing capacity, costs associated with vaccine transportation, and concerns related to vaccine wastage. Facilitators of timely HepB-BD vaccination included: vaccine availability, storage, and hospital births occurring during immunization days. Overarching themes identified as barriers among pregnant women were lack of hepatitis B knowledge, limited understanding of HepB-BD importance, and limited access to vaccines for births occurring outside of a health facility. Facilitators were high vaccine acceptance and willingness for their infants to receive HepB-BD if recommended by providers. Findings indicate the need for enhanced HepB-BD vaccination training for HCWs, educating pregnant women on HBV and the importance of timely HepB-BD, updating policies to enable HepB-BD administration within 24 hours of birth, expanding HepB-BD availability in public and private hospital maternity wards for all facility births, and outreach activities to reach home births.

Despite global efforts to improve vaccination coverage, the number of zero-dose and under-immunized children has increased in Africa, particularly in Nigeria, which has over 2.1 million unvaccinated (zero dose) children, the highest in the continent. This scoping review systematically maps and summarizes existing literature on the barriers and facilitators of immunization in Nigeria, focusing on regional inequalities. A comprehensive search of electronic databases was conducted, encompassing all data from their inception to October 2023, to identify articles on the determinants of routine immunization uptake in Nigeria. Eligible studies were evaluated using predefined criteria, and the data were analyzed and visualized. The results revealed distinct regional variations in factors influencing immunization practices across Nigeria’s six geopolitical zones. Identified barriers include logistical issues, socio-economic factors, cultural influences, and systemic healthcare deficiencies. Key facilitators across multiple zones are health literacy, maternal education, and community leader influence. However, unique regional differences were also identified. In the North-East, significant factors included peer influence, robust reminder systems, provision of additional security, and financial incentives for health facilities. In the North-West, perceived vaccine benefits, fear of non-immunization consequences, urban residence, health literacy, and antenatal care visits were reported as crucial. Perceived benefits of vaccines and trust in healthcare providers were identified as predominant factors in the North-Central zone In the South-East, maternal autonomy, health literacy, and fear of non-immunization consequences were important. In the South-South, peer influence and reminder systems like WhatsApp and SMS were notable, alongside higher maternal education levels. The South-West highlighted maternal autonomy, peer influence, health card usage, high maternal education, and supportive government policies as critical factors. Our findings underscore the need for region-specific interventions that address these unique barriers to improve immunization coverage across Nigeria. Tailored approaches that consider the socio-economic, cultural, and logistical challenges specific to each region are essential to bridge the immunization gap.

Students in the universities mostly live independently from their parents or guardians, some of them for the first time. This gives them freedom and opportunity for high risk behavior such as unplanned and unprotected sex. The results of such sexual experimentation may include unplanned and or unwanted pregnancies that may lead to unsafe abortions and sexually transmitted infections (STIs) including HIV/AIDS. Contraception has the potential to prevent unwanted pregnancies, abortion, and STIs. This study aimed at assessing the general knowledge on contraceptives, sexual practices, and level of utilization of contraceptives devices among unmarried students of the Bayero University Kano. We did an institutional based cross-sectional descriptive study. We administered a pretested, self-administered, structured questionnaire to randomly selected unmarried undergraduate students of the institution. We analyzed data using Microsoft Excel 2016 and Epi-info7. A total of 300 students were interviewed. The median age for respondents was 23 years with an age range of 16-25 years. Male respondents made up 61.3% (184) while the females made up the remaining 38.7% (116). Also, 158(47.33%) of respondents lived outside the school campus, while 158(52.67%) lived in the school hostels. Knowledge on contraception was 87.7% among respondents with internet (91%) and media (89.3%) as the commonest sources of knowledge. Proportion of sexually active students was 10.67%, while prevalence of contraceptive utilization among sexually active students was 15.63%. About 8(25%) had their sexual debut at < 16years of age, 22(68.75%) at ages between 16-20years, and 4(12.5%) above 20years of age. All sexually active respondents practice vaginal sex. Most sexual debuts were planned (44.75 %) and with friends (86.4%), and they occurred between the ages of 16-20years age group in 70.3% of respondents. Even though knowledge on contraceptive used was high among the respondents, utilization of contraceptives among sexually active students was low, thus creating a window for possible unintended and unwanted pregnancies among these group of students.

Background: The year 2020 Lassa fever (LF) outbreak had the greatest disease burden and this can place an enormous strain on the already overstretched healthcare system and can potentially increase morbidity and mortality due to infectious diseases. Therefore, having a knowledgeable healthcare workforce with appropriate skills and competencies to prevent and manage outbreaks of a neglected infectious disease such as LF in Nigeria will potentially enhance public health. Thus, this survey assessed the level of knowledge of LF and its prevention and control (PC) measures amongst the healthcare workers (HCWs) during a LF outbreak in Katsina state, Nigeria. Methodology/Principal findings: During this cross-sectional survey, HCWs complete a validated 29-item questionnaire comprising 18 items on the knowledge of LF and its PC measures and an item on global self-evaluation of their LF knowledge. Psychometric properties of the questionnaire were evaluated. Chi-square and binary logistic regression analyses were conducted. Out of 435 HCWs invited, a total of 400 participated in the study (92% response rate). The majority of participants (51.8%) demonstrated inadequate LF knowledge, with 62.9% of those scoring low having a high self-perception of their LF knowledge with the global scale. This LF knowledge over-estimation was predicted by LF training status (odds ratio (OR) 2.53; 95% CI: 1.49–4.30; p = 0.001). The level of LF knowledge and its PC measures among the study participants was low (11.60±8.14, 64.4%) and predicted by participants’ LF training status (OR 2.06; 95% CI: 1.19–3.57; p = 0.009), place of work (OR 1.82; 95% CI: 1.07–3.08; p = 0.03) and their designations (OR 2.40; 95% CI: 1.10–5.22; p = 0.03). Conclusion: The level of knowledge of LF and its PC measures among the HCWs surveyed was suboptimal and participants’ LF training status, place of work and occupational category were the significant predictors. In addition, LF knowledge overestimation on a global scale was observed among a majority of HCWs and this was also predicted by LF training status. Therefore, there is a critical need for health authorities in Nigeria to prioritize continuous on-the-job training of HCWs on priority neglected tropical diseases such as Lassa fever.
