Vaccines summit in London seeking life-saving funds

Countries meeting in London are to be asked to give an extra £2.3bn ($3.7bn) by 2015 to fund vaccines against two of the biggest killers of children - pneumonia and diarrhoeal disease.

The Global Alliance on Vaccines and Immunisation (Gavi) says the money could help save four million lives in four years.

Its conference is being led by UK Prime Minister David Cameron and Microsoft tycoon Bill Gates.
