COVID-19 and vaccines in Africa: a descriptive and thematic analysis of Twitter content
2021
Introduction : As coronavirus disease 2019 (COVID-19) vaccines become available, it becomes important to understand public perceptions of the vaccines and implementation plans. The social media platform Twitter TM , which publicly shares information, serves as an important source of content related to COVID-19 vaccines. This study employed a qualitative descriptive design to examine content related to COVID-19 vaccines posted by Twitter users located in Africa. Methods : Data were collected from Twitter between the 11 th and the 16 th of December 2020 using the NCapture tool. We searched Twitter using the terms 'coronavirus', 'COVID-19 vaccine' and 'Africa' to identify the nature and content of tweets related to COVID-19 and vaccines shared by Twitter users from the African region. Descriptive statistics were used to describe the characteristics of Twitter accounts and thematic analysis helped determine, analyse, and clarify patterns of meaning (themes) emerging from the tweets. Results : The study found n=208 Twitter accounts, the majority (n=69; 33%) from South Africa and most (42%; n=87) from news agencies. The final dataset included n=212 tweets. The most used hashtag was #Covid19vaccine(s). Four themes were identified: i) capacity for vaccine production, ii) vaccine procurement, iii) vaccine logistics, and iv) perceived safety and efficacy of vaccines. The capacity of countries in Africa to manufacture a COVID-19 vaccine was deemed minimal and most tweets questioned Africa’s ability to procure vaccines based on the costs. Tweets also centred around the distribution of vaccines, storage and roll-out and the need to leverage existing solar-powered technologies to enhance the cold supply chain in Africa's remote locations. Questions about the safety and efficacy of vaccines developed in under one year were also raised. Conclusions: Concerns about vaccine procurement and readiness for distribution were dominant topics. These public concerns can be important in informing policymakers in preparation for the roll-out of vaccines in these contexts.
