ABSTRACT
Introduction: At the end of 2020, several vaccines against covid-19 have been validated by the World Health Organization in order to stop this pandemic. However, a growing number of people, including health care workers (HCWs), express reluctance to be vaccinated against covid-19. Aim(s): To determine the causes of reluctance towards the covid-19 vaccine expressed by health care personnel. Method(s): This was a descriptive and cross-sectional study that interested the HCWs of the Charles Nicolle Hospital of Tunisia reluctant to the anti-covid-19 vaccination during the period from October 25, 2021, to January 31, 2021. The causes of renunciation were studied through a pre-established questionnaire. Result(s): Our population consisted of 112 HCWs. The average age was 41.1 +/-10.2 years old. Females were predominant (66.1%). The average professional seniority was 12.4 +/- 11.3 years. Our population consisted mainly of blue-collar workers (29.1% of cases) followed by senior technicians (26.4% of cases) and nurses (24.5% of cases). The HCWs belonged to the medical services in 45% of the cases. Previous infection with SARS -Cov2 virus was noted in 55.4% of the HCWs. The reasons for renunciation were: the potential adverse effects that the vaccine could cause in the long term (59.8%), the speed of clinical trials is a source of concern (30.4%), and at the use of new vaccine technologies, particularly mRNA vaccines remains a factor of distrust (26.8%). Conclusion(s): It is imperative to strengthen the confidence of the HCWs towards the different vaccines against covid19 while insisting on the benefit-risk balance which always remains in favor of vaccination.
