Past has shown that it wasn’t. See swine flu vaccinations.

  No vaccine is 100% safe. That doesn't exist. The real question is the risk/benefit profile. Does the benefit of the vaccine outweigh the risks. That was a "no" for the swine flu vaccine since the outbreak fizzled out quickly. If tens of thousands were dying every month from the swine flu, then the vaccine may have still be worth it even with the GBS side effect.
