India administered more than 180 million doses in August as it continues to ramp up its vaccination drive to stave off a third wave of Covid.
The government aims to vaccinate all eligible Indians by the end of 2021.
It has so far given more than 700 million doses of three approved jabs, reports BBC.
India is using three vaccines - the Oxford-AstraZeneca jab, known locally as Covishield; Covaxin by Indian firm Bharat Biotech; and Russian-made Sputnik V.
More than half of India's eligible population - some 473 million people - have received at least one dose of a Covid vaccine, official data says.
But only about 17% of eligible adults have been fully vaccinated since the beginning of the drive in January.
