[Status of COVID-19 vaccination among staff at the Tengandogo University Hospital Center, Ouagadougou, Burkina Faso, June to December 2021].

Introduction: According to the WHO, 278 million confirmed cases of COVID-19 had been recorded worldwide by the end of 2021, resulting in approximately 5.4 million deaths. In Burkina Faso, 17,632 cases and 318 deaths were recorded. Vaccination is one of the strategies implemented to control the pandemic. This study aimed to evaluate the status of the COVID-19 vaccination program among staff at a referral hospital in Burkina Faso.

Methods: From June 2 to December 31, 2021, we conducted a descriptive study at Tengandogo University Hospital (CHU-T). The study involved all staff members. Information was obtained through face-to-face and telephone interviews and self-administered questionnaires. Quantitative variables were described using the mean and standard deviation, while qualitative variables were described using proportions. All vaccinated individuals responded to the questionnaire. Unvaccinated individuals were volunteers.

Results: A total of 31% (174 out of 559) of healthcare workers were vaccinated, with a mean age of 41 ± 8 years. Men accounted for 55% (94/174) of the vaccinated workers. The main worker profiles were 62 doctors (35.6%), 62 nurses (35.6%), and nine ward boys and girls (5.2%). The main reason for accepting the vaccine was protection against the disease, reported by 132 workers (76%). There were 134 unvaccinated subjects who agreed to participate in the study. Their average age was 32.8 ± 7.3 years. The proportion of women was 60%. Uncertainty about vaccine effectiveness was the main reason for not getting vaccinated, cited by 106 workers (79%). Minor adverse events were reported by 136 of the vaccinated workers (78%). No serious adverse events were reported. Four vaccinated workers developed symptomatic SARS-CoV-2 infection during the study period.

Conclusion: The proportion of vaccinated subjects was low. Interventions to improve healthcare workers' adherence to vaccination should be developed.
