But perhaps the cleverest aspect of the influenza marketing strategy surrounds the claim that ‘flu’ and ‘influenza’ are the same. The distinction seems subtle, and purely semantic. But general lack of awareness of the difference might be the primary reason few people realize that even the ideal influenza vaccine, matched perfectly to circulating strains of wild influenza and capable of stopping all influenza viruses, can only deal with a small part of the ‘flu’ problem because most ‘flu’ appears to have nothing to do with influenza. Every year, hundreds of thousands of respiratory specimens are tested across the US. Of those tested, on average 16% are found to be influenza positive.
…It’s no wonder so many people feel that ‘flu shots’ don’t work: for most flus, they can’t.
[According to CDC statistics], ‘influenza and pneumonia’ took 62,034 lives in 2001—61,777 of which were attributable to pneumonia and 257 to flu, and in only 18 cases was the flu virus positively identified.
