A vaccine against swine flu will be fast-tracked for use in Britain in just five days, with 130 million doses on order.

Peter Holden, the British Medical Association’s lead negotiator on swine flu, who has been attending Department of Health meetings on the outbreak, said that GPs’ surgeries were prepared for one of the biggest winter vaccination campaigns in almost 50 years.) q) @! k6 H6 {# S3 G; ~ G/ K

! B- S* k$ P! a. a; YIt is likely that the elderly would be given a seasonal flu jab to guard against other strains — as happens every year — as well as the swine flu vaccination, Dr Holden said. The new vaccine is likely to be given in two doses but it could be left as a single jab if this is found to provide high rates of immunity.( y- a3 P# d& A" z; n6 E2 j" ]# c

"The high-risk groups will be done at GPs’ surgeries. People are still making decisions over this, but we want to get cracking before we get a second wave, which is traditionally far more virulent,” he said.

2 L p- e4 R* t5 pBritain has a stockpile of 500 million doses of Tamiflu (ostelamivir), the anti-viral drug used to treat flu symptoms. A vaccine however would provide a preventative measure against illness and would be used to ease pressure on the health service and the wider economy if several million people become ill, as expected at the height of a pandemic.

The EMEA said that fast-tracking would not be at the expense of patient safety, adding: “The vaccines are authorised with a detailed risk management plan. There is quite a body of evidence regarding safety on the trials of the mock-up, and the actual vaccine could be assessed in five days.”8 I+ ]- Q, D) r4 e t& Q
