That is indeed the question – particularly in relation to the flu jab which is on offer at this time of year. It’s over three years now since doubt was first cast on the effectiveness of the flu jab, particularly in protecting elderly people. Now it seems that a new study published in the US shows that the 2007-08 flu vaccine was only 44% effective, which made it the worst flu season the worst since 2003-04.

In fairness, flu vaccines are formulated based on health officials’ educated guesses about which strains of the virus are most likely to be circulating in a given year. Three of these strains are picked for inclusion in the vaccine and when they guess correctly, the vaccine is usually between 70 and 90% effective.

Sounds like a bit of a lottery to me, and again going the natural route I prefer to boost my system with a seasonal acupuncture tune up and regular doses of Echinacea and vitamin C – it seems to work for me.
