Brazzaville, 27 May 2021 – Africa needs at least 20 million doses of the Oxford-AstraZeneca vaccine in the next six weeks to get second doses to all who received a first dose within the 8 12-week interval between doses recommended by the World Health Organization (WHO).
A single dose of the Oxford-AstraZeneca vaccine gives around 70% protection for at least 12 weeks. Data on the protection from one dose after 12 weeks is limited, however COVID-19 antibodies have been found in the body up to 6 months after one dose. The full course provided with a 12-week interval gives 81% protection for an extended period.
