Ouagadougou: Medical student Astride Yanogo successfully defended her doctoral thesis in medicine on Friday at Joseph Ki-Zerbo University.

According to Burkina Information Agency, Astride Yanogo is now a Doctor of Medicine. She defended her doctoral thesis on Friday at the Training and Research Unit in Health Sciences (UFR/SDS) of Joseph Ki-Zerbo University. The theme of her research focused on the determinants of adherence of women seen in prenatal care to the vaccination of girls against human papillomavirus (HPV) in the Boulmiougou health district.

This study aimed to analyze the determinants of adherence among women receiving prenatal care regarding the vaccination of young girls against human papillomavirus, using the Health Belief Model (HBM) as a framework. The research was a cross-sectional study with descriptive and analytical objectives, conducted from January to April 2026 with 424 pregnant women in the Boulmiougou health district.

Data for the study were collected through a structured questionnaire and analyzed using STATA software. A multivariate analysis based on the Health Belief Model identified the key determinants influencing adherence to HPV vaccination. The study revealed a high rate of adherence to HPV vaccination at 96.3%.

Despite the strong support for the vaccination, there was a discrepancy in effective vaccination coverage, with only 53% of girls aged 9 to 14 having actually received the vaccine. The main barriers identified included a lack of information about the vaccine, unfamiliarity with vaccination schedules and locations, and fears related to potential side effects. Healthcare workers emerged as the primary source of information for the study participants.

Following her presentation, the jury deemed Yanogo's document admissible and awarded her the highest distinction with congratulations. She then took the Hippocratic Oath. The chairman of the jury, Professor Hyacinthe Zamane, formally declared Astride Yanogo a doctor of medicine. Her research work was supervised by Dr. Sibraogo Kemtore, who served as her thesis director.
