FLU vaccines may be far less effective at combating seasonal outbreaks than previously thought, researchers state in the British Medical Journal , BMJ adding that they may not be worth the cost and effort required to produce them.
According to a review by Tom Jefferson published in the BMJ 26/10/06, there is little clinical evidence that the vaccines reduce deaths significantly, hospital stays and time off work among those most at risk from seasonal flu, including the over-65s and those with chronic heart and lung conditions. This is not a great relevation to many of us, however to have this view published in the BMJ is extraordinary.
Public health officials worldwide recommends the use of influenza vaccines to prevent outbreaks. More than 15 million doses of vaccine have been ordered for use this winter in Britain.
Jefferson, states vaccines given to children under 2 have the same effect as if they were given a placebo. He is calling for an urgent re-evaluation of vaccination campaigns. I wont be holding my breath, because influenza viruses mutate and vary from year to year, it is difficult for scientists to study the precise effects of vaccines and that most existing studies are of poor quality.
