Doctors still have some concerns about a number of people affected by a flu outbreak at a nursing home in Donegal, which has claimed the lives of six elderly people.
Three men and three women, all aged over 85 died from the flu between March 22 and April 2 at Nazareth House outside Buncrana.
The Health Service Executive has said that all appropriate treatment and control measures are in place for the 11 people still showing symptoms of the outbreak.
It has emerged that four people from the six who died had received the flu vaccine.
But Dr Darina O'Flanagan, Director of the Health Protection Surveillance Centre, said the vaccine was not ideally matched to the strain of flu circulating this year.
