The value of flu shots

My elderly but very active mother has always been sceptical of the benefit of flu vaccination, and every winter takes pleasure in pointing out which of her family and acquaintances have succumbed to the "flu" despite having had the shot that year. (I continually point out that there is a difference between a heavy cold and the flu, but never get far with this argument.)

However, it seems that some doctors also question the value of the flu vaccination programs, and even the evidence for their value in the elderly is a bit all over the place:

Only among people who suffer bronchitis could he find good evidence that flu vaccination was worthwhile. In infants up to two, vaccination was no better than placebo and in older children there was little evidence of benefit.

Nor could he find enough evidence of benefit among people with chronic chest problems, asthma and cystic fibrosis.

In healthy adults the best evidence was that, on average, flu vaccination of a population would prevent 0.1 per cent of a working day lost.

Combined studies of the elderly showed a variation from no effect to a 60 per cent difference when "all cause mortality" was measured.

"These findings are both counter-intuitive and implausible as other causes of death are far more prevalent in older people," he writes.

Score one for my mother?
