Save the Children claim a million lives could be saved

The charity Save the Children has launched a report on Monday, No Child Born to Die, which highlights the potential funding shortfall for global immunisation.
The report says there is a critical shortage of 3.5 million health workers in poor countries, without whom millions of children will face illness and early death.
Save the Children says it will be campaigning for rich nations to increase support for global immunisation, and for the pharmaceutical industry to lower the price of vaccines.
The Gavi Alliance, a global health partnership of public and private sectors for immunisation, is already running a scheme attempting to get the new pneumonia vaccine to children in the developing world.
Nineteen countries, many of them in Africa, will get the new jab first.
Speaking to the BBC's Fergus Walsh at a clinic in Nairobi, Save the Children's Catherine Fitzgibbon says far too many children are dying every day from preventable diseases.
