Drug companies announce price cuts for poor countries

A number of drug companies have announced substantial price cuts for life saving vaccines paid by people in developing countries.

One company, GlaxoSmithKline, is offering discounts of up to 95%.

The list of vaccines include ones that protect against a diarrhoea related disease that kills more than half a million children every year.

Andrew Witty is the chief executive of GlaxoSmithKline and he explained why the company has decided to do this.
