A warning that the new swine flu jab is linked to a deadly nerve disease has been sent by the Government to senior neurologists in a confidential letter.
The letter from the Health Protection Agency, the official body that oversees public health, has been leaked to The Mail on Sunday, leading to demands to know why the information has not been given to the public before the vaccination of millions of people, including children, begins.
It tells the neurologists that they must be alert for an increase in a brain disorder called Guillain-Barre Syndrome (GBS), which could be triggered by the vaccine.
GBS attacks the lining of the nerves, causing paralysis and inability to breathe, and can be fatal.
The letter, sent to about 600 neurologists on July 29, is the first sign that there is concern at the highest levels that the vaccine itself could cause serious complications.
It refers to the use of a similar swine flu vaccine in the United States in 1976 when:
- More people died from the vaccination than from swine flu.
- 500 cases of GBS were detected.
- The vaccine may have increased the risk of contracting GBS by eight times.
- The vaccine was withdrawn after just ten weeks when the link with GBS became clear.
- The US Government was forced to pay out millions of dollars to those affected.
Concerns have already been raised that the new vaccine has not been sufficiently tested and that the effects, especially on children, are unknown.
It is being developed by pharmaceutical companies and will be given to about 13million people during the first wave of immunisation, expected to start in October.
Top priority will be given to everyone aged six months to 65 with an underlying health problem, pregnant women and health professionals.
The British Neurological Surveillance Unit (BNSU), part of the British Association of Neurologists, has been asked to monitor closely any cases of GBS as the vaccine is rolled out.
