AHMEDABAD: Zydus Cadila Healthcare has started producing its potential Covid-19 vaccine for which it will seek emergency use authorisation in May or June, its managing director told Reuters, with an aim to make up to 240 million doses a year. Government officials have said they are eagerly waiting for Cadila to seek approval for ZyCoV-D soon, as a record rise in coronavirus infections have led to a public health disaster in the world's most populous country after China. "We have just started producing doses," Sharvil Patel said in a Microsoft Teams interview on Friday. "But it is not meaningfully large." He said the aim was to produce 10 million doses a month starting June, taking the in-house annual capacity to 120 million. The rest of the production, as required, will mainly come from third-party producers.
