Spreading the flu, it actually doubles your chances of getting the flu to get the flu vaccine.

Is a 100% undebated absolute fact that they have never guessed the right flu virus for the mutation of what the main flu is the next year. And it's always a whole bunch of flus, dozens and dozens of them. Does nothing to protect you from the next flu if it's not the exact flu.

Alex isn't really being honest there about the flu vaccine. It is true that oftentimes flu strains pop up in human populations that aren't the ones that are covered by that year's vaccine, but it's pretty ridiculous to say that scientists have never guessed the right strain.
