AstraZeneca Plc’s Covid vaccine is about as effective against the new strain of the virus that emerged in the U.K. as against the initial version, according to a study by the shot’s co-developer, the University of Oxford.
Protection against symptomatic infection was comparable for the new variant as well as the earlier strain, according to the study, which analyzed swabs taken from volunteers from October through mid-January. The findings are disclosed in a preprint version of the study that wasn’t peer-reviewed.
