New bid to halt polio in Angola
"The good news is that we know this outbreak could be stopped very rapidly"
- Oliver Rosenbauer, Global Polio Eradication Initiative
A mass polio immunisation campaign is starting in Angola in a bid to vaccinate all children under five.
The campaign is part of a series of programmes aimed at stopping a polio outbreak that has paralysed 24 children this year alone.
Over 7m vaccine doses are set to be delivered.
The World Health Organisation (WHO) says previous attempts to stop the virus circulating failed because too few children were vaccinated.
This outbreak in Angola started in 2007 and the WHO now considers it the greatest risk to Africa's polio eradication efforts.
