Perceptions, attitudes, practices, and factors associated with COVID-19 vaccination among travelers in the Democratic Republic of the Congo.

BACKGROUND

Vaccination against COVID-19 has been the primary public health measure implemented to limit the spread of the disease. However, there is still considerable scope for improvement in vaccine coverage, particularly in sub-Saharan African countries. The factors influencing the acceptance or reluctance of the COVID-19 vaccine have been widely studied, but there is a gap in the literature with regard to dynamic populations, particularly travelers, who are one of the priority target groups for vaccination. This study assessed the perceptions, attitudes and practices regarding the COVID-19 vaccine, and explored factors associated with vaccination status among travelers.

METHODS

A cross-sectional survey was conducted at several points of entry (PoEs) selected for six survey sites (N'djili airport, Ngobila beach, Lufu, Boma, Moanda, and Kananga), located in three provinces of the Democratic Republic of the Congo (Kinshasa, Kongo Central and Kasaï Central), from February 20 to March 05, 2023. The data were summarized and logistic regression models were performed to assess factors associated with vaccination status.

RESULTS

A total of 2742 travelers were included in this survey. Of these, 54% had received at least one dose of COVID-19 vaccine. Multivariable logistic regression analyses revealed that that several factors were significantly associated with vaccination status. These included age (under 60 years), marital status (single), occupation (other than healthcare worker), mode of travel (other than airplane), and poor perceptions of the vaccine. The most frequently cited reasons for vaccination among respondents who had received the vaccine were the prevention of COVID-19 infection and the ease of travel. In contrast, unvaccinated participants expressed greater concern about the safety and effectiveness of the vaccine, as well as vaccine-related side effects. Furthermore, travel disruption and inappropriate vaccination sites have been identified as significant obstacles to the acceptance of vaccination at the PoEs.

CONCLUSIONS

It is essential that awareness initiatives address concerns and misconceptions about vaccine safety and effectiveness. The influence of social media platforms may be harnessed for the dissemination of accurate information from the most trusted information sources, including healthcare professionals, to the target population. In addition, accompanying measures should be considered to facilitate vaccination compliance at different PoEs.
