Keighley-district people who have still to receive the seasonal flu jab are being urged to get vaccinated now to avoid festive fever.

Regional NHS bosses say the vaccine takes up to two weeks to become effective.

Rona Daniels, screening and immunisation lead for West Yorkshire, said: “We want to encourage people to get their flu jab as soon as possible to reduce the risk of falling ill over Christmas.

“The jab is offered free of charge to individuals who have a high risk of catching flu, such as those aged 65 or over, pregnant women and people with long-term health problems.

“Flu is an extremely contagious disease with quick onset of symptoms including a high temperature, sore throat, headache and muscle and joint pain.

“Despite popular belief, the vaccine cannot give you flu as it doesn't contain the active virus needed to do this.”

Among those supporting the call is Worth Valley councillor Glen Miller, the Tory group leader on Bradford Council.

Coun Miller, who has received his jab, said: “Flu isn’t just a cold – it can be very serious and can lead to complications that can be fatal for those in at-risk groups.

“I myself fall into one of these as my immune system suffered as a result of an injury which I sustained whilst serving in the army. Anyone who thinks that they may be in an at-risk group is encouraged to ask the question to be sure.”

The vaccination is available from GP surgeries and some pharmacies.
