AstraZeneca Plc's COVID-19 vaccine is effective against delta and kappa variants, which were first identified in India, the company said on Tuesday, citing a study.
The Oxford University study examined the ability of monoclonal antibodies in the blood of recovered people and vaccination to neutralize delta and kappa variants, the statement said.

Last week, an analysis by Public Health England (PHE) showed that vaccines made by Pfizer Inc. and AstraZeneca offer more than 90% higher protection against hospitalization than the delta version.
The results of the latest Oxford study build on a recent analysis by PHE, the company said.
The chief scientist of the World Health Organization said on Friday that the delta variant is becoming the dominant version of the disease globally.
