A second nurse has been charged over the death of two babies shortly after vaccination in Samoa.
Police on Wednesday arrested the woman and charged her with manslaughter and conspiring to defeat justice.
She's understood to have been released from custody awaiting a court appearance.
Another nurse appeared in court earlier this week facing the same charges, along with negligence, and was granted bail
Both are due to appear in Samoa's Supreme Court towards the end of this month.
The two one-year-olds died quickly after being immunised for measles, mumps and rubella at Safotu District Hospital, in Savai'i, in early July.
Senior health officials have said there is no issue with the vaccine and have been working with the World Health Organisation since the babies' deaths to rebuild public confidence.
