From suspicions about Chinese-made vaccines in Zimbabwe and conspiracy theories in Ivory Coast about Covid-19 being âa planned event by foreign actorsâ to Somalia, where the Islamist militant Al-Shabaab group is warning people theyâre âguinea pigsâ for AstraZeneca, large sections of Africans are steering clear of vaccines. Only about 17.5% of the doses available in Ivory Coast and 19% in Zimbabwe have found their way into arms. Already lagging behind the rest of the world in its inoculations, the wave of vaccine skepticism -- made worse by a lack of trust in local governments and misinformation on social media -- threatens to put the continent even further behind.
