A fire Thursday broke out at a facility of the world's biggest vaccine maker in India, killing five people.
Chief Executive Officer of the Serum Institute of India said the incident would not affect vaccine production.
The blaze occurred in the western city of Pune.
The cause is still under investigation.
Four people were rescued from the six-floor building.
Those who died are believed to have been construction workers as the building was still being built.
The Serum Institute of India is in partnership with Oxford University and AstraZeneca to produce the Covishield vaccine.
In December, the company said it was producing 50 to 60 million doses of Covishield per month, with production to be scaled up to 100 million doses this month.
