Should people be worried about the side effects of getting the flu vaccine?

"Common side effects from a flu shot could include soreness or swelling at the site of the injection, headaches, low-grade fever, nausea, muscle aches or fatigue. Those minor side effects are an indication your immune system is responding as  it should to the vaccination. You will experience much more severe fever, aches and other symptoms if you catch the flu without being vaccinated against it."
