The CDC says that last year, the effectiveness of the flu shot was less than 40%, and the year before that, it was only 14% effective. That's astonishingly low.
Just think if your polio or tetanus vaccination were only 14% reliable. You'd think something is wrong. Vaccines are not supposed to have such low rates of effectiveness.
The problem is that the flu mutates every year and becomes something slightly different. The companies that make the vaccine base their vaccine on last year's flu, which is already gone. They try to tinker with last year's flu to guess what this year's flu will be like, but they are often wrong, hence the low effectiveness rate.
But I wonder if the effectiveness rate might be even lower – say, zero percent. That's because when measuring "effectiveness" of the vaccine, they are measuring only who is vaccinated and doesn't catch the flu. Many people have natural immunity and would not get the flu regardless of whether they are vaccinated.
