The poster has visual impact. However, in the USA, Black mistrust of vaccinations relates to memories such as the Tuskegee syphilis experiment, and I doubt that the socio-economic coercion tactics associated with Covid are going to overcome that mistrust. Other racial/religious groups have other concerns eg Halal, fear of sterility. It is may be significant that the mistrust level amongst healthcare workers is not very much lower than in the general population. So, it may be more productive to encourage prevention through health promotion eg diet and vitamin supplements, especially vitamin D. A duckduckgo search on 'black asian covid vaccine low uptake' and on 'covid africa mortality vitamin d' will bring up many links on this subject.
Thank you very much for the insight on this subject. I know that the black community has well-founded issues with vaccinations, and I did take this into consideration, hoping to not be blind to that and tone deaf to real concerns in the design and content of the poster. I hope this will possibly help to give people the information they need to make the best decisions for themselves and their families, and to feel supported and more confident in the options being presented to them. I really do appreciate your input on this matter, and thank you for taking the time to share this information with me. The more informed I am, the better work I can produce to help spread useful and helpful messages with my design.
