AstraZeneca is to start clinical trials to test a combination of its experimental COVID-19 vaccine with Russia's Sputnik V shot to see if this can boost the efficacy of the British drugmaker's vaccine, Russia's sovereign wealth fund said on Friday.

AstraZeneca said it was considering how it could assess combinations of different vaccines, and would soon begin exploring with Russia's Gamaleya Institute, which developed Sputnik V, whether two vaccines based on a common-cold virus could be successfully combined.
