A new scientific study published in The Lancet reveals that influenza vaccines only prevent influenza in 1.5 out of every 100 adults who are injected with the flu vaccine.

So, when the media (or your doctor, or pharmacist, or CDC official) says these vaccines are "60% effective," what they really mean is that you would have to inject 100 adults to avoid the flu in just 1.5 of them. Or, to put it another way, flu vaccines do nothing in 98.5% of adults.
