Police in Samoa have filed a manslaughter charge against a nurse over the death of two babies last month after they received the MMR vaccine.
The nurse has already been charged with conspiracy to defeat the course of justice and negligence.
RNZ Pacific understands police filed the manslaughter charge last Friday against the nurse who is still in custody.
The nurse will appear in the district court tomorrow but it's likely the matter will be referred to the Supreme Court.
Association offers help to jailed nurse
The head of the Samoa Nurses' Association said she would visit the nurse who faces the charges.
The association's president, Sonialofi Papalii, said it was a really difficult time as the investigations were still ongoing and so much was still unknown.
"We have to seek legal support for her, and support the girl as well," Ms Papalii said.
"[We need] to reassure her psychologically of what has happened, to be patient with what's going on.
"Hopefully God will assist her in all her pain," she said.
Ms Papalii said many nurses had been upset by the situation and the association was trying to reassure them and encouraged them to keep up their work and maintain standards.
Researchers say an endangered killer whale that drew international attention off Washington state in the US as she carried her dead calf on her head for more than two weeks is finally back to feeding and frolicking with her pod.
The Center for Whale Research in Washington state says it watched the orca, known as J35, chase a school of salmon in Haro Strait west of San Juan Island yesterday.
The whales have been struggling because of a lack of salmon, and J35's calf died soon after birth on July 24. The mother carried the baby on her head for at least 17 days, in an image of grief that struck an emotional chord worldwide.
She finally abandoned the carcass as it decomposed.
Center for Whale Research founder Ken Balcomb says he is immensely relieved to see J35 returning to typical behaviour.
