Knowledge, attitudes, and adherence of the Cape Verdean population to the COVID-19 vaccine

Background The spread of the COVID-19 pandemic at the end of 2019, with its well-known consequences in terms of morbidity and mortality, has triggered an intense mobilization of the scientific community in the search for knowledge about the SARS-Cov2 virus and the development of a vaccine. Objective This study aims to investigate the knowledge, perceptions, attitudes, and intentions of the resident Cape Verdean population regarding the COVID-19 vaccine. Methods This was a descriptive, cross-sectional, and analytical study involving 1704 resident Cape Verdeans, whose ages ranged from 16 to 60 years old and the majority of participants were male (52.6%). The data was collected using the Google form platform between March 9 and 15, 2021. Results The data indicated that the majority of participants (95.8%) knew of at least one approved vaccine against COVID-19, and this knowledge (74.9%) was obtained from television, radio, and newspapers. The Oxford-AstraZeneca vaccine was the best known (54.1%) among the study subjects and the majority of respondents (69.7%) had enough information to consciously decide whether or not to get vaccinated against COVID-19. The majority (68.0%) of participants were in favor of the COVID-19 vaccine being administered to all interested people. About 59% of participants considered the COVID-19 vaccine to be safe and 49.6% of participants intended to get vaccinated when the time came. The greatest vaccine hesitancy was related to fear of side effects (21.4%), followed by the fact that it was developed too quickly (12.8%). Health professionals were seen as the priority group (81.5%) to be vaccinated. Conclusions The results show that the Cape Verdean population had a good level of knowledge about the COVID-19 vaccine. Despite initial hesitation, the vast majority of participants were willing to get vaccinated. These data suggest that awareness-raising, education, and information campaigns about the COVID-19 vaccine should be strengthened to reduce hesitation and increase confidence and adherence to the COVID-19 vaccine among Cape Verdean residents.
