Participating in a vaccine trial for COVID-19 in Senegal : trust and information /Ridde, Valéry Ba, M. F. Gaye, I. Diallo, A. I. /Bonnet, Emmanuel Faye, A. Vaccine trial COVID-19 Senegal acceptability participation This research aims to understand the level and determinants of people's willingness to participate in a vaccine trial for COVID-19 in Senegal. We conducted a telephone survey among a marginal quota sample of 607 people over 18 years of age. Only 44.3% of the participants wanted to participate in a vaccine trial for COVID-19, with females intending to participate more than males (AOR = 1.82, 95% CI [1.22-2.72]). Participants who intended to be vaccinated against COVID-19 (AOR = 6.48, 95% CI [4.12-10.4]) and who thought that being infected with the coronavirus would have a significant impact on their health (AOR = 2.34, 95% CI [1.57, 3.51]) were more likely to agree to take part in the COVID-19 vaccine trial. Confidence in the vaccine, health personnel, and the government in the fight against the pandemic are key factors in participants' willingness to participate in a vaccine trial in Senegal. 2021 text https://www.documentation.ird.fr/hor/fdi:010082596 fdi:010082596 Ridde Valéry, Ba M.
