A medical specialist in New Zealand is worried about the impact the death of two infants in Samoa will have on vaccination programmes.
The babies died last Friday after receiving the MMR vaccination for measles, mumps and rubella at Savaii's Safotu hospital.
Middlemore Hospital intensive care specialist David Galler, has worked in Samoa and told Morning Report it's important people don't rush to judgement.
"I think our hearts go out to all those families, but also to the community in Samoa who will have great fear now about the risks of vaccination and that will also stir the fires of the anti-vaccination campaigns in other places, and I'm in particular, our own country, New Zealand," he said.
Dr Galler said the investigation into the infants' deaths will be thorough, because the ramifications are serious.
