AstraZeneca said on Saturday that its coronavirus vaccine offered only limited protection against mild cases of the South African variant of the virus. The company based its conclusion on early data from a trial and study released by South Africa's University of Witwatersrand and Oxford University.
"In this small phase I/II trial, early data has shown limited efficacy against mild disease primarily due to the B.1.351 South African variant," said an AstraZeneca spokesman.
"However, we have not been able to properly ascertain its effect against severe disease and hospitalization, given that subjects were predominantly young healthy adults. Oxford University and AstraZeneca have started adapting the vaccine against this variant and will advance rapidly through clinical development so that it is ready for Autumn delivery should it be needed," the company added.
