Measles, mumps, rubella vaccine safe - NZ health officials

The use of a vaccine is under investigation in Samoa after the death of two infants. The children died on the same day at the same hospital after receiving vaccinations for measles, mumps and rubella. But New Zealand authorities say the MMR vaccine is safe and there are no concerns for New Zealand children. Dr Helen Petousis-Harris is research director of the Immunisation Advisory Centre. She talks to Gyles Beckford.
