UK swine flu vaccinations under way

Sir Liam Donaldson, chief medical officer for England, said it was important for frontline health and social care workers to get themselves vaccinated against swine flu along with other groups classified as a "priority" or at risk.

He said: "This is the first pandemic for which we have had vaccine to protect people.

"I urge everyone in the priority groups to have the vaccine - it will help prevent people in clinical risk groups from getting swine flu and the complications that may arise from it. It's important for frontline health and social care workers to have the vaccine.

"It will help prevent them and their families getting the virus from patients, it will stop them passing the virus on to their patients, it will potentially protect them from mutated strains and it will reduce the disruption to NHS services caused by people being absent due to illness."

Sir Liam's call comes amid concern about the effects of a possible postal strike on the vaccination programme. GPs will begin receiving deliveries of the vaccine from Monday and will send appointment letters to patients classified as at risk.

Sir Liam said: "We are a little bit worried about the postal strike because GPs send their letters out, letters of appointment, so we are working very hard to try and get round that, ensuring that people get their appointments in time."

Asked how they would get appointment letters to people if a strike goes ahead, he said: "By bundling the mail up and ensuring that it is delivered because some mail will still be delivered for urgent situations, so we are going to try and sort out that little glitch - which isn't a particularly welcome thing to happen in the middle of having this vaccine."

The immunisation programme, offering more than 11 million people the vaccine, began with hospitals vaccinating frontline health care workers and their patients who fall into at risk categories against swine flu.
