Some of India's private hospitals have cancelled orders for Russia's Sputnik V vaccine as they struggle to sell Covid-19 shots amid surging supplies of free doses of other vaccines offered by the government.

Some industry officials said low demand and the extremely cold storage temperatures required have spurred at least three big hospitals to cancel orders for Sputnik V, sold only on the private market in the world's biggest producer of vaccines.

"With storage and everything, we have cancelled our order for 2,500 doses," said Jitendra Oswal, a senior medical official at Bharati Vidyapeeth Medical College and Hospital in the western city of Pune.

"Demand is also not great. There is a class of people, barely one per cent, that wanted to go for Sputnik. For the rest, anything would do."
