Whooping cough outbreak: Pregnant women to be vaccinated
28 September 2012 Last updated at 14:05 BST
Hundreds of thousands of pregnant women across the UK are to be offered a whooping cough vaccine to protect babies from an escalating outbreak of the disease.
Very young babies are at the greatest risk of serious complications. Ten have died in the UK this year.
The injection, available from Monday, should boost a mother's defences, which are then passed onto the baby.
Health officials say there are no safety concerns about the vaccine.
