AstraZeneca vaccine is less effective against South African Covid-19 variant

The Oxford/AstraZeneca vaccine offers only limited protection against mild disease caused by the South African variant of coronavirus, according to research.

However, the company said early data from the study, due to be published tomorrow, has shown the vaccine can protect against severe disease caused by the mutation.

“We do believe our vaccine could protect against severe disease, as neutralising antibody activity is equivalent to that of other Covid-19 vaccines that have demonstrated activity against more severe disease, particularly when the dosing interval is optimised to eight to 12 weeks,” a spokesman said.

It comes after research released on Friday indicated that the Oxford/AstraZeneca vaccine is effective at fighting the new UK Covid-19 variant.
