More than half of young children in Kent were not vaccinated when flu season hit, according to Public Health England.

The latest figures show that just 45% of four to 10 year olds had received the flu vaccine at the end of November.

In Medway the figure was even lower at just 43%.

That's slightly lower than the rate across England, where 47% of primary school children were up to date on their annual dose.

Of 116,974 primary school children in Kent, 64,282 had not been given the vaccine, which is delivered in school as a nasal spray.

Public Health England advises headteachers to make sure their pupils are protected before the winter months.

Of the youngest children eligible, in Reception, 51% had been given the spray - more than the 40% among the oldest, in Year 5.

"But even with a modest uptake you see a reduction of flu in the general community..." Dr Richard Pebody

The flu vaccine programme runs from the beginning of September to the end of January, with Public Health England reporting uptake rates throughout the winter.

By the end of the previous winter, 55% of four to 10-year-olds in Kent were covered, suggesting uptake could increase through December and January.

But with flu season starting in December it's still important to make sure children are vaccinated as early as possible, according to the NHS.

Dr Richard Pebody, head of flu at Public Health England, said: "Flu can be nasty for little children. Some develop a very high fever or complications of flu, such as bronchitis or pneumonia, and may need hospital treatment.

"Children also tend to be super-spreaders of flu, so if they get it, they are likely to infect more vulnerable older family members.

"The best form of protection against flu is to get the vaccine if you are eligible, and to practise good respiratory and hand hygiene."

Dr David Elliman, immunisation expert at the Royal College of Paediatrics and Child Health, said that uptake of the flu vaccine is always lower than other routine jabs.

He added: "But even with a modest uptake you see a reduction of flu in the general community. Any uptake is better than nothing."

Last winter was the worst flu season in a decade in England, causing 3,175 hospital admissions and 320 deaths.

In October, doctors in Kent were worried that thousands of elderly people could be at risk because because of a shortage of vaccinations.
