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.
