Background: Vaccination is an important tool for reducing infectious disease morbidity and mortality. In the past, less than 80% of children 12-23 months of age were fully immunized in Burkina Faso.
Objectives: To describe coverage and assess factors associated with adherence to the vaccination schedule in rural area Burkina Faso.
Methods: The study population was extracted from the Nouna Health and Demographic surveillance system cohort. Data from four rounds of interviews conducted between November 2012 and June 2014 were considered. This study included 4016 children aged 12-23 months. We assessed the effects of several background factors, including sex, factors reflecting access to health care (residence, place of birth), and maternal factors (age, education, marital status), on being fully immunized defined as having received Bacillus Calmette-Guérin (BCG), three doses of diphtheria-tetanus-pertussis and oral polio vaccine, and measles vaccine by 12 months of age. The associations were studied using binomial regression to derive prevalence ratios (PRs) in univariate and multivariate regression models.
Results: The full vaccination coverage increased significantly over time (72% in 2012, 79% in 2013, and 81% in 2014, p = 0.003), and the coverage was significantly lower in urban than in rural areas (PR 0.84; 0.80-0.89). Vaccination coverage was neither influenced by sex nor influenced by place of birth or by maternal factors.
Conclusion: The study documented a further improvement in full vaccination coverage in Burkina Faso in recent years and better vaccination coverage in rural than in urban areas. The organization of healthcare systems with systematic outreach activities in the rural areas may explain the difference between rural and urban areas.

Background/aim: Vaccine refusal or delay remains a significant public health concern, leading to lower vaccination rates and increasing the risk of preventable diseases.
Patients And Methods: The study included 404 mothers and 413 children, assessing vaccination coverage and conducting telephone interviews with mothers who declined vaccines to understand their reasons.
Results: Children of mothers who supported vaccination were more likely to be fully immunized compared to those with hesitant mothers.

This study evaluates the association between immunization program (IP) activities aimed at increasing HPV vaccination among adolescents and their impact on initiation rates. Our data sources are: (i) 2016 AIM Annual Survey and (ii) 2019 National Immunization Survey-Teen. We estimated the prevalence of HPV vaccine initiation using a multilevel Poisson model, combining state-level IP data and individual characteristics of adolescents.

To prevent widespread epidemics such as influenza or measles, it is crucial to reach a broad acceptance of vaccinations while addressing vaccine hesitancy and refusal. To gain a deeper understanding of Japan's sharp increase in COVID-19 vaccination coverage, we performed an analysis on the posts of Twitter users to investigate the formation of users' stances toward COVID-19 vaccines and information-sharing actions through the formation. We constructed a dataset of all Japanese posts mentioning vaccines for five months since the beginning of the vaccination campaign in Japan and carried out a stance detection task for all the users who wrote the posts by training an original deep neural network.

Background: Cervical cancer is the second most common cancer in women in South Africa. Infection with high-risk types of human papillomavirus (HPV) is the cause of cervical cancer, which can be prevented by HPV vaccination. However, there is wide variation in HPV vaccination coverage among the urban districts of South Africa; with the lowest coverage being 40% in eThekwini, KwaZulu-Natal.
