The symptoms people experience as "the flu" are actually withdrawal symptoms from the mind control agents spread via chemtrails. That's why the govt promotes the "flu vaccine" which is in fact just a long acting mind control drug. The shot is required because the dispersal patterns of chemtrail drugs is greatly limited during fall/winter months.
This isn't just the case with the flu. It's the secret purpose behind ALL vaccines. Have you ever actually seen any viruses? Of course not. Sure, you've seen pictures that are reported to be viruses, but those are just artist's fabrications. The "Virus Project" was started long ago by governments around the world as a way of controlling those considered subversive. Later it was expanded to include all peasants.
