Factors associated with COVID-19 vaccine hesitancy in Senegal: a mixed study

IntroductionThe most effective way to control the COVID-19 pandemic in the long term is through vaccination. Two of the important components that can hinder it are vaccine hesitancy and vaccine refusal. This study, conducted before the arrival of the vaccines in Senegal, aims to assess and identify factors associated with hesitancy to the COVID-19 vaccine. MethodsThis study was an explanatory, sequential, mixed-methods design. We collected quantitative data from December 24, 2020, to January 16, 2021, and qualitative data from February 19 to March 30, 2021. We conducted a marginal quota sampling nationwide. We used a structured questionnaire to collect data for the quantitative phase and an interview guide with a telephone interview for the qualitative phase. We performed descriptive, bivariate, and multivariate analyses with R software version 4.0.5 for the quantitative phase; and performed manual content analyses for the qualitative phase. ResultsWe surveyed 607 people for the quantitative phase, and interviewed 30 people for the qualitative phase. Individuals who hesitated or refused to be vaccinated represented 12.9% and 32.8%, respectively. Vaccine hesitancy was related to gender, living in large cities, having a poor attitude towards the vaccine, thinking that the vaccine would not help protect them from the virus, being influenced by people important to them, and lacking information from health professionals. Vaccine refusal was related to living in large cities, having a poor attitude towards the vaccine, thinking that the vaccine would not help protect them from the virus, thinking that the vaccine could endanger their health, trusting opinions of people who were important to them, and lacking information from health professionals. ConclusionThe results of the study show that the factors associated with hesitancy and refusal to be vaccinated against COVID-19 are diverse and complex. Reducing them will help to ensure better vaccination coverage if the current challenges of vaccine accessibility are addressed. Therefore, governments and health authorities should intensify their efforts to promote vaccine confidence and reduce misinformation.

Participating in vaccine research for COVID-19 in Senegal: trust and information

This research aims to understand the level and determinants of peoples 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. Participants who intended to be vaccinated against COVID-19 (OR = 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 (OR = 2.34, 95% CI [1.57, 3.51]) were more likely to agree to take part in the COVID-19 vaccine research. Confidence in the vaccine, health personnel, and government in the fight against the pandemic are key factors in intending to participate in vaccine research in Senegal.

Acceptability of contact management and care of simple cases of COVID-19 at home: a mixed-method study in Senegal

IntroductionIn mid-2020, due to the health system challenges from increased COVID-19 cases, the Ministry of Health and Social Action in Senegal opted for contact management and care of simple cases at home. The studys objective was to determine the acceptability of contact management, home care of simple cases of COVID-19, and its associated factors. MethodThis was a sequential mixed-method study. We collected data from June 11, 2020, to July 10, 2020, for the quantitative survey (N=813) and from August 24 to September 16, 2020, for the qualitative survey (N=30). We carried out a sampling strategy using marginal quotas at the national level. We collected data using a structured questionnaire in a telephone interview for the quantitative survey and using an interview guide formulated from the quantitative surveys initial results for the qualitative data. We assessed acceptability using binomial logistic regression combined with content analysis. ResultsThe care of simple cases of COVID-19 at home was well accepted (78.5%). This result was justified for some (saturation of the health system) but not for others (risk of contamination). The use of home contact management was less accepted (51.4%), with risk limitation as the main reason given. The acceptability of home-based care for simple cases was positively associated with knowledge of the modes of transmission of the virus (ORaj: 1.55 [95%CI: 1.04,2.28]), regular research into COVID-19 (ORaj: 2.12 [95%CI: 1.45,3.12]), belief in the existence of treatment (ORaj: 1.82 [95%CI: 1.19,2.83]), and confidence in institutional information (ORaj: 2.10 [95%CI: 1.43,3.10]). The acceptability of home-based contact management was positively associated with knowledge of the modes of transmission of the virus (ORaj: 1.77 [95%CI: 1.27,2.48]), regular research for information on COVID-19 (ORaj: 2.39 [95%CI: 1.76,3.26]), and confidence in the government in the fight against the epidemic (ORaj: 1.51 [95%CI: 1.10,2.08]). ConclusionRegular information on the disease, knowledge of its mode of transmission and trust in institutions are factors in accepting COVID-19 management at the community level. Authorities should take these factors into account for better communication to improve the acceptability of home-based care.
