Flu Vaccine Recommendations for UK, Germany, France, Spain, Italy
Unlike the US, where the CDC recommends that nearly everyone over 6 months of age get the annual seasonal influenza shot, many other countries only recommend the shot (or, "the jab" as it is known in the UK) for person's aged 60 or older. In fact, most reserve the recommendation for people over 65 (with no underlying medical condition).
The US stands in sharp contrast, where the recommendation is that "everyone 6 months and older should get a flu vaccine each year starting with the 2010-2011 influenza season."
By contrast, the Europeans suggest that only those with underlying medical conditions (and not as many as in the US) and those over 65 get the shot.
It is not clear what the leading driver is for this disparity. It could be a number of factors, including; influence of the large pharmaceutical companies, legal structures (in the US vaccine makers shielded from civil liability), structural and political reasons, or, perhaps just hysteria.
