Union Minister Nitin Gadkari on Tuesday suggested that more pharma companies should be allowed to make the Covid-19 vaccine in the country during the pandemic to scale up production. <br /> <br />Addressing Vice Chancellors of Universities in India virtually, Gadkari said he will also request Prime Minister Narendra Modi to bring a law for allowing more pharma companies to manufacture life-saving drugs by paying 10 per cent royalty to the patent holder of the drug. <br /> <br />"If the demand of vaccine is more than its supply then it creates a problem. So, instead of one company, 10 more companies should be allowed to make vaccines by paying 10 per cent royalty to the original patent holder of the vaccine," he said.
