The Supreme Court on Monday sought the Centre’s response on a PIL accusing multinational pharma giant Glaxo Smithkline of having conducted unauthorised trials of its cancer vaccine on tribal girls.

A bench headed by Justice KS Radhakrishnan, while seeking reply from the health ministry, also directed the Christian Medical College, Vellore, to examine the medical records of the seven girls who have allegedly died during such trials, and submit a report to it.
