TWO in five people eligible for free flu vaccines in Southampton did not take them up last winter, figures show.

Now England’s top doctors are urging people to protect themselves and their families from flu amid warnings that the number of new cases could peak over the next few weeks.

NHS England data shows that 70,174 people were eligible for free flu vaccines in Southampton last winter – but only 60% had one.

The low rate meant 27,722 vulnerable people were left unprotected in the area through the key winter months.

Dr Ben Marshall, a consultant respiratory physician at University Hospital Southampton, said: "The low take-up last year was disappointing and concerning, but I am hopeful we will see an improvement this year given awareness of the potential for a difficult flu season.

"There is still time for people to get vaccinated, including children. Although we were seeing and detecting flu cases in November, numbers won't rise until next month."

Flu can be unpleasant for anyone but if sufferers are otherwise healthy it usually clears up without treatment within a week.

However, for certain groups of people including the elderly, the very young, pregnant women and people with other health conditions, it can be serious and even fatal.

The NHS offers free flu vaccines to all these groups due to their increased vulnerability.

The figures show that toddlers were much less likely to have had the jab than their older neighbours in Southampton, with parents taking only 44 per cent of two year olds and 46 per cent of children aged three for the vaccinations.

The uptake rate among Southampton's senior residents was better – but at 74 per cent, around 8,300 over 65s still went without.

Just 49 per cent of pregnant women received the vaccine, and 50 per cent of under 65s with health conditions which put them at heightened risk.

As flu levels ramp up this year, Public Health England has introduced its Catch It, Bin It, Kill It campaign, to help prevent the spread of the highly infectious disease during Christmas, Hanukkah and New Year celebrations.

It says hundreds of thousands could see their holiday plans turned to misery if flu levels rise as expected in late December and early January.

Professor Stephen Powis, the NHS's national medical director, said: “Whether it’s missing out on your Christmas dinner, the Boxing Day match or a New Year’s party, nobody wants to be laid low by flu while the festivities are in full swing.

“It’s good to see that more people over the age of 65 have already got their jab. For older people and those with underlying health conditions, getting flu is particularly bad news because it can lead to really serious conditions like pneumonia and bronchitis, which can mean a lengthy stay in hospital.

“And we know that children are ‘super spreaders’ of flu, particularly around the holiday season when they’re more likely to see elderly relatives.

“So our message is simple: the flu season is here, get your jab now. It might be the difference between a Christmas to remember, and one to forget.”
