You've all been reading the misleading headlines in the DM and Telegraph today I assume? They have scraped the bottom of the unhelpful front page headline barrel in my book.
Flu jabs not like measles jabs (that give close to 100% lifelong protection , they are always a lottery. The powers that be (WHO etc) identify the most common strains circulating in the southern hemisphere winter and gamble that these will be the most likely ones to be circulating in the northern hemisphere. They then start producing the vaccine for the winter jabs. Some winters they have gambled correctly and the jab saves many many lives. This year there is a strain of virus circulating that has not been stopped by the jab. There will still be some of the predicted strains around, and those who have been inoculated will not get these.
I think this year's bigger surge in winter deaths illustrates what would happen normally, if there were no flu jabs.
Makes sense to take a longer view - if you have a flu jab ever year for 10 years, your chance of having true influenza during that time is considerably reduced. On the other hand you can not have the jab and increase your risk having a nasty disease that could make you ill for weeks or put you in hospital, or even finish you off a few years early. What a tough choice.
