According to official sources, the central government on Monday had asked SII and Bharat Biotech to lower the prices of their Covid-19 vaccines amid criticism from various states who accused the companies of profiteering during such a major crisis.
The issue of vaccine pricing was discussed at a meeting chaired by Cabinet Secretary Rajiv Gauba.
Many states have objected to the different prices for the vaccines.
Last week, SII had defended the pricing of the Covishield vaccine, saying the earlier price was based on advance funding and now it has to invest in scaling up and expanding capacity to produce more shots.
"The current situation is extremely dire, the virus is constantly mutating while the public remains at risk. Identifying the uncertainty, we have to ensure sustainability as we must be able to invest in scaling up and expanding our capacity to fight the pandemic and save lives," the company had earlier said.
The government last week waived basic customs duty on import of COVID vaccines, medical grade oxygen and related equipment for three months.
India has announced expansion of its Covid-19 vaccination drive by allowing its large 18-plus population to get inoculated from May 1.
