Thousands of people aged 65 and over in Bradford are once again being reminded to ward off flu by having a free flu jab this winter.

Around 48,000 people in Bradford have received letters reminding them to get their flu jabs this year.

The letter asks them to book an appointment with their GP to get the jabs.

The flu jab is free to everyone aged 65 and over and for people with certain long-term conditions.

Last year more than 70 per cent of over-65s came forward for the jab and this year health bosses hope to improve upon this figure. Bradford's flu immunisation co-ordinator, Dr Suzanna Mathew, said: "Relatively few people have suffered from a bad dose of flu in the last few years because people are being responsible about having the jab.

"But what many people don't realise is that the make-up of the flu virus changes every year, so it is important to get a new jab at the start of each winter. Each year's jab is manufactured specifically to combat the current strain of flu."

The jab is available not only to over-65s but also to parents of children aged over six months with asthma, diabetes or weakened immunity due to disease or treatment.

Nationally, TV ads featuring a nasty 'flu bug' cartoon are being broadcast. Chief Medical Officer Liam Donaldson said: "There is a big difference between a cold and flu - thousands of deaths are linked to flu every year.

"Flu tends to last for up to two weeks, giving you fevers, chills, extreme fatigue and aching muscles as well as the more cold-like symptoms of sore throats and runny noses.

"If you are 65 years or older, or you suffer from illnesses such as asthma, diabetes or serious heart or kidney disease you are particularly at risk from flu."

Further information about the flu jab can be found in leaflets available from GP surgeries, by contacting the doctor or practice nurse or by calling NHS Direct on 0845 4647.
