AstraZeneca to release modified vaccine against South African

AstraZeneca could release a modified version of its coronavirus vaccine which can tackle the South African variant by the end of 2021, The Guardian reports.

Sarah Walters, AstraZeneca’s Austria country manager, told the Kurier newspaper that the firm had “started modifications to the vaccine for the South African variant and we expect it will be ready by the end of the year, should it be needed”.

According to Reuters, Walters also said that studies which have so far suggested that the vaccine was less effective against the South African variant were “too small to draw final conclusions”.
