Abstract
In French Guiana, a French overseas territory in South America facing a fourth wave of COVID-19, vaccination coverage is very low, both in the population and among health care workers (HCWs). Vaccine hesitancy concerned 35.7% of the latter in early 2021. The objective of this complementary study is to understand barriers and levers and to adapt messages to increase vaccination coverage among HCWs. We conducted a regional cross-sectional survey of HCWs with a questionnaire containing open-ended questions exploring factors associated with vaccine hesitancy and the needs to adapt the vaccination campaign in French Guiana. The discourses were analyzed using a qualitative approach based on grounded theory, with open coding of data by themes and construction of abstract categories. The analysis of the 357 responses collected from January to March 2021 reveals several trends. The ethical aspect of the HCWs’ role emphasizes the importance of getting vaccinated themselves (to protect patients, to set an example...) and of vaccinating as many people as possible, including the most geographically or socially distant, such as undocumented migrants. However, some HCWs remain suspicious of the vaccine with concerns over the efficacy and side effects, of health institutions, and of the pharmaceutical industry. The role of fake news circulating on social networks has been widely discussed. Efforts to explain and convince HCWs must be continued in French Guiana using the identified levers to improve the acceptability of vaccination.
