Do you need to take the swine flu vaccine? Some medical centers require taking the vaccine. Scare tactics are a powerful tool to intimidate people into taking the vaccine. The CDC has been concealing their data regarding the need for the vaccine. CBS did its own study on the incidence of swine flu and their numbers were much lower than those of the CDC. One person in 5000 will die from the swine flu and most of these people are immunosuppressed.
