A shortage of oxygen at Vanuatu's main hospital, the Port Vila Central Hospital, stopped all surgery on Tuesday.
The hospital reports that ten operations had to be put off, but normal services have now resumed.
Meanwhile the midwife of Melsisi Health Centre on Pentecost island, Edwidge Tabi, says since May this year, they have not vaccinated new born babies due to the lack of oxygen to ensure their vaccine store room is kept cool.
She says the situation is serious because the children are not being protected against disease.
