COVAX has so far received 17.7 million AstraZeneca doses from SII, of the 60.5 million doses India has shipped in total, and many countries are relying on the programme to immunise their citizens.
There have been no vaccine exports from India since Thursday, the foreign ministry's website showed, as the country expands its own immunisation effort.
“Everything else has taken a backseat, for the time being at least,” said a source. “No exports, nothing till the time the India situation stabilises. The government won’t take such a big chance at the moment when so many need to be vaccinated in India.”
