Primary school pupils aged five and upwards in Sheffield are being lined up to be immunised against flu in their classrooms.
A programme to protect thousands of children from the virus is due to begin across the city and will for the first time this year will be offered to some infant school pupils.
Sheffield City Council leaders are urging parents to make sure their children are protected.
Between October and December, youngsters in Year One and Two will receive the vaccine in the form of a nasal spray delivered in their classrooms to protect them from the virus. This is in addition to two, three and four-year-olds being vaccinated by GPs.
The vaccination programme is being delivered by the Sheffield Children’s Hospital Trust’s school nursing service.
Councillor Jackie Drayton, Cabinet Member for Children, Young People and Families at Sheffield City Council, said: “Flu can be a very unpleasant illness for children. Annual immunisation not only provides important protection to individual children, but will also reduce spread to their families and the wider community, protecting those who are at increased risk of becoming seriously ill from flu.”
