India to fund capacity boost at Serum Institute as vaccines run short

India is set to accept the Serum Institute of India's (SII) request for a 30 billion rupee ($400 million) grant to boost its capacity to make the AstraZeneca Covid-19 vaccine, a government source with knowledge of the matter told Reuters.

SII, the world's biggest vaccine maker, sought the funds to increase its monthly capacity to more than 100 million doses by the end of May, from up to 70 million currently.

The country has administered more than 112 million doses of the shot so far, the highest in the world, despite concerns about some people overseas developing blood clots after receiving the vaccine.

The Indian government is in fact struggling to meet demand for the drug from many states as infections spread rapidly.

"We are clear that we will give whatever support is necessary to develop and boost the availability of vaccines in the country," the source said on Sunday, declining to be identified as he was not authorised to speak publicly on the matter.

A finance ministry spokesman declined to comment. SII, which will soon also start making the Novavax Covid-19 vaccine, did not respond to a request for comment.

India has so far injected 123 million vaccine doses, including nearly 11 million of a domestically developed shot known as Covaxin.

The government is also trying to boost output of Covaxin and has also changed rules to fast-track imports of vaccines developed by Pfizer, Moderna  and Johnson and Johnson.
