JOHANNESBURG (AP) — South Africa’s decision to suspend the use of the Johnson & Johnson vaccine due to preliminary reports of rare blood clots has left the country without any shots as it struggles to combat an aggressive coronavirus variant. South Africa’s more than 1.5 million confirmed coronavirus cases represent more than 30% of all the confirmed cases in Africa. It has only inoculated 290,00 health care workers so far, all with the Johnson & Johnson vaccine. South Africa’s plans to begin large-scale vaccinations next month are dependent upon deliveries of the Johnson & Johnson and the Pfizer-BioNTech vaccines. Some health experts criticized South Africa’s move to pause the Johnson & Johnson’s product at such a critical juncture.
