Health clinics and flu vaccination sessions for elderly people in Ledbury are to be combined this autumn, following fears that particularly virulent strains of flu are likely to hit the UK this winter.

The warning comes from the Government's chief medical officer, Professor Liam Donaldson, who has called for at-risk groups to be vaccinated before the viruses take hold in late autumn.

The types of flu expected included the so-called New Caledonian and the Moscow strains, both said to be "debilitating".

In the past three weeks, St Katherine's Surgery has written to all patients who are 65 and over, inviting them to attend one of three special clinics.

Surgery manager David Lloyd said: "This year, St Katherine's Surgery is altering the way it is carrying out its flu vaccination programme.

"We have booked the Community Centre on Thursday October 11 and 18, and November 1, between 2pm and 4pm.

"Approximately 1,800 patients, 65 years of age and over, have been invited to attend. Vaccination will also be available for at risk groups of all ages, such as diabetic, severe asthmatics and people with heart complaints

"At the same time, Age Concern and Herefordshire Primary Care Trust will man a stall offering advice on safe and healthy living."

Mr Lloyd explained that topics covered would include the importance of staying warm, the benefits of exercise and how to reduce the risks of falls.

He said: "It is hoped that this event will provide patients with a good start to combat the ordeals that the coming winter will present."

Across the UK, the Government has set surgeries the target a vaccinating at least 65 per cent of those aged 65 and over, a rise of five per cent on last year's figure.
