Ahmedabad-based Zydus Cadila's three-dose Covid-19 vaccine ZyCoV-D is expected to get an emergency-use nod from the expert committee this week, sources said.

Union Health Minister Mansukh Mandaviya last week during the question hour in the Rajya Sabha had said, "The government expects that in October-November, four more Indian pharmaceutical companies will start production of indigenous vaccines that will help to meet the domestic demand, Biological E and Novartis vaccines will also be available in the market in the coming days, while Zydus Cadila will soon get an emergency use nod from Expert Committee."
