Vaccine supply crunch adds to risk of COVID-19 resurgence Format 6 May 2021 Brazzaville, 6 May 2021 - With Africa-bound COVID-19 vaccine doses from the Serum Institute of India delayed for the foreseeable future, slow vaccine rollouts and new variants making inroads, the risk of a new wave of infections in Africa remains high. Delays and shortages of vaccine supplies are driving African countries to slip further behind the rest of the world in the COVID-19 vaccine roll out and the continent now accounts for only 1% of the vaccines administered worldwide, down from 2% a few weeks ago. COVID-19 vaccine rollouts have been exemplary in some African countries, yet around half, or 19 million, of the 37 million COVID-19 vaccine doses received in Africa have been administered so far, according to reports from African countries.
