During the quarter ended June, the company reported a nearly three-fold rise in the income from operations at Rs 19.15 crore, against Rs 6.99 crore reported during the corresponding period of the previous fiscal.

Analysts say that the hopes of vaccines to thwart the spread of novel coronavirus may further lift the healthcare stocks led by the vaccine-manufacturing companies. /IANS
